7 Best Red Light Therapy Devices for Gum Disease in 2026 – Reduce Inflammation, Support Healthier Gums at Home

Gum disease affects nearly half of all adults over 30 in the United States – and for millions of people, the standard treatment cycle of scaling, root planing, prescription rinses, and periodic surgery feels endless. Gingivitis and periodontitis are fundamentally driven by bacterial overgrowth, chronic inflammation, and compromised tissue repair – and these are precisely the biological targets where red light therapy has demonstrated meaningful, peer-reviewed clinical results.

Photobiomodulation (PBM) – the delivery of specific wavelengths of red and near-infrared light to biological tissue – has been used in professional dental settings for decades. What has changed dramatically in recent years is the availability of clinically calibrated intraoral LED devices designed for daily home use. These devices deliver therapeutic wavelengths directly to gum tissue, periodontal pockets, and the oral mucosa – reducing pro-inflammatory cytokines, killing periodontal pathogens through antibacterial photodynamic action, stimulating collagen synthesis in damaged gum tissue, and accelerating the repair of receding gumlines.

This guide reviews 7 of the best red light therapy devices for gum disease available in 2026, across intraoral LED mouthpieces, advanced aPDT systems, and a leading sonic toothbrush for mechanical gum care – each assessed for wavelength accuracy, clinical support, format, and real-world outcomes.

After reviewing every device on this list for wavelength credentials, gum disease-specific clinical relevance, dual red+blue action, safety record, and ease of daily use, the Novaa Oral Care Pro by NovaaLab is our top pick for 2026. Its 16 medical-grade LEDs combining red (660nm) for tissue repair and inflammation reduction with blue (450nm) for antibacterial action, paired with FDA clearance, a 60-day risk-free trial, and a warranty extendable to 3 years, make it the most complete and credentialled at-home LED oral care device for gum disease management.

Does Red Light Therapy Actually Help Gum Disease? The Science Explained

Gum disease – encompassing both gingivitis (surface-level gum inflammation) and periodontitis (deeper bacterial infection of the periodontal pockets and supporting bone) – is fundamentally an inflammatory and microbial condition. Red and near-infrared light therapy address both of these root drivers through documented biological mechanisms.

Research published in AIMS Biophysics (Hamblin, 2017) confirmed that photobiomodulation reduces pro-inflammatory cytokines – including TNF-α, IL-1β, and IL-6 – through modulation of mitochondrial signalling and NF-κB pathway activity. These are the same inflammatory mediators elevated in active gingivitis and periodontitis, meaning PBM targets gum disease’s underlying inflammatory cascade rather than masking symptoms. The result is measurable reductions in gingival bleeding, pocket depth, and erythema with consistent treatment.

Blue light at 405–450nm operates through a fundamentally different but complementary mechanism – antibacterial photodynamic action. Research published in Photobiomodulation, Photomedicine, and Laser Surgery confirmed that 405–450nm blue light generates reactive oxygen species that destroy the cell membranes of periodontal pathogens including Porphyromonas gingivalis, Fusobacterium nucleatum, and Treponema denticola – the three bacteria most directly associated with aggressive periodontitis – without generating antibiotic resistance and without harming beneficial oral flora at therapeutic doses.

Near-infrared wavelengths (810–850nm) penetrate deeper than red light – reaching into the periodontal ligament, alveolar bone crest, and tooth-supporting structures – where they stimulate collagen synthesis in the periodontal membrane and support the regenerative processes involved in reattachment of gum tissue to the tooth root surface.

A landmark 6-month randomised controlled trial published in the Journal of Periodontology (2026) – the HOPE-CP study, 200 periodontal maintenance patients – found that patients using home-applied dual-light photodynamic therapy alongside standard mechanical cleaning were twice as likely to reach healthy gum status compared to mechanical cleaning alone. This represents the strongest direct clinical evidence yet for home LED phototherapy as an adjunct to conventional periodontal care.

Research published in the European Journal of Physical and Rehabilitation Medicine (De Oliveira et al., 2022) further confirmed photobiomodulation’s established pain control and anti-inflammatory efficacy across musculoskeletal and soft tissue conditions – the same inflammatory pathways active in periodontal disease – reinforcing the mechanistic basis for oral LED therapy.

Which Wavelengths Work Best for Gum Disease?

Understanding the wavelength profile of any oral LED device is essential – not every light colour helps periodontal disease, and device claims vary significantly in their clinical grounding.

Red (630–660nm): The primary anti-inflammatory and tissue-repair wavelength for gum disease. Stimulates collagen synthesis in damaged periodontal tissue, promotes microcirculation in inflamed gum tissue, reduces gingival redness and swelling, and activates cellular repair mechanisms in receding gumlines. Research confirms 660nm specifically activates cytochrome c oxidase in gingival cells, enhancing mitochondrial ATP production and accelerating tissue regeneration.

Blue (405–450nm): The primary antibacterial wavelength for oral use. At 405–450nm, blue light triggers endogenous porphyrins in periodontal bacteria – particularly P. gingivalis – producing reactive oxygen species that destroy bacterial cell walls. This is the same mechanism used in professional photodynamic therapy in dental clinics, now available in home devices. Critical for papulopustular gum presentations and active bacterial infection.

Near-Infrared (810–850nm): Penetrates through gum tissue into the periodontal ligament and supporting alveolar bone crest. At 810nm specifically, NIR light is absorbed by ICG photosensitiser in aPDT systems (Lumoral), providing both photobiomodulation and deep antibacterial action in periodontal pockets. At 850nm without photosensitiser, it supports collagen remodelling and periodontal tissue regeneration at depth.

Dual-action devices (red + blue simultaneously): The most clinically effective format for gum disease – combining surface antibacterial action (blue) with deep anti-inflammatory and regenerative action (red/NIR). Devices offering both wavelengths in a single session (Novaa Oral Care Pro, dpl® Oral Care, Starlite Smile Wireless) address the full pathological spectrum of gum disease in one treatment.

The Novaa Oral Care Pro is NovaaLab’s flagship oral health device and the most complete LED intraoral mouthpiece for gum disease on this list. Its dual-wavelength approach directly addresses both core pathological drivers of periodontal disease in a single 10-minute session: the red (660nm) mode activates cell regeneration, reduces gingival inflammation, promotes collagen synthesis in damaged periodontal tissue, and relieves pain associated with active gum disease; the blue (450nm) mode kills harmful bacteria in the oral cavity – including the periodontal pathogens responsible for gingivitis progression and bad breath – while simultaneously whitening teeth.

The 16 medical-grade LEDs are manufactured by NovaaLab’s dedicated medical supplier and are calibrated to deliver verified wavelengths rather than the approximate or untested output seen in many budget intraoral devices. FDA clearance provides meaningful clinical assurance that the device has been reviewed for safety and performance at an institutional level. The device is recommended by over 100 dentists and physicians, and NovaaLab’s 150,000+ customer base includes documented case after case of verified hygienist-confirmed gum improvements – notably several users reporting their periodontists commenting on measurable gum health improvement after 4–8 weeks of consistent use. The 60-day risk-free trial and extendable 3-year warranty are among the strongest buyer protections in this category.

The Nunawave Oral Care Pro occupies a distinct position on this list – its mouthguard format is the only device here that serves a dual function as both a photobiomodulation therapy device and a night-guard style protector, making it particularly relevant for gum disease patients who also experience bruxism (teeth grinding), which compounds periodontal stress and gum recession. The combination of red (660nm) and near-infrared (850nm) wavelengths delivers therapeutic light at two complementary depths – 660nm addressing surface gingival inflammation and tissue repair, 850nm penetrating deeper into the periodontal ligament for structural collagen remodelling and deeper tissue support.

The USB-compatible design – connecting directly to iPhone, Android, USB, or USB-C without requiring a dedicated charger or power base – is one of the most practical formats on this list for daily compliance. Users simply plug into whatever device they have at hand, place the mouthguard, and treat for 20 minutes. The BPA-free silicone construction is soft enough for overnight-style comfort, and dentist endorsements for the device specifically mention its suitability for post-procedure oral recovery – a use case where the anti-inflammatory and collagen-stimulating properties of red and NIR light are particularly well-evidenced.

Pros & Cons

Pros

• Red (660nm) + NIR (850nm) – deeper penetration than blue-only or red-only devices
• Mouthguard format – dual protection for bruxism patients with concurrent gum disease
• 32 total LEDs (16 red + 16 blue) – full bilateral coverage of upper and lower arches
• No dedicated charger required – USB-compatible with any existing device
• Dentist-endorsed – recommended for post-procedure recovery

Cons

• No blue light mode – lacks direct antibacterial wavelength for active bacterial infection
• Less clinical documentation than Novaa Oral Care Pro or dpl® Oral Care

The NovaaLab Gum Care Sonic Toothbrush does not contain LED light therapy. It is a premium sonic toothbrush specifically engineered for gum disease patients – positioned here as the ideal mechanical cleaning companion to use alongside an intraoral LED device such as the Novaa Oral Care Pro, rather than as a standalone phototherapy device. The combination of daily sonic brushing and LED mouthpiece therapy mirrors the protocol used in clinical trials showing the strongest periodontal outcomes – consistent mechanical plaque disruption combined with photobiomodulation-driven bacterial reduction and tissue repair.

At 48,000 vibrations per minute, the GumCare Sonic Toothbrush generates microbubble action that reaches interdental spaces and the subgingival margin – areas where manual brushing consistently underperforms and where periodontal bacteria accumulate. The pressure sensor is particularly significant for gum disease patients: overly aggressive brushing is a direct driver of gum recession and enamel erosion, and the automatic intensity reduction when excessive force is detected actively protects vulnerable gum tissue during the daily brushing routine. The ultra-soft bristles minimise gingival trauma while maintaining effective plaque removal. NovaaLab dentists specifically recommend this device to patients using the Oral Care Pro as their complementary mechanical hygiene tool.

Pros & Cons

Pros

• Pressure sensor – protects receding gums from over-brushing damage during daily use
• 48,000 VPM – generates microbubble action reaching subgingival spaces
• Ultra-soft bristles – purpose-designed for sensitive and disease-affected gum tissue
• 60-day trial + up to 3-year warranty – same buyer protection as Novaa Oral Care Pro
• Ideal daily companion to intraoral LED therapy for complete gum disease protocol

Cons

• No LED light therapy – mechanical cleaning only, not a photobiomodulation device
• Needs to be used alongside an LED device for full gum disease management
• ~$99.90 – adding to an LED mouthpiece represents combined investment

More to Know

Light Type: None (sonic mechanical only) | Wavelengths: N/A | LED Count: N/A | Session Duration: 2 minutes (2x daily) | Warranty: Up to 3 years | Device Format: Sonic electric toothbrush – gum-care specialist

User Monica D.C. explains:

The Novoral Sonic Toothbrush does a great job of keeping the teeth and gums clean and healthy. The initial impression is that it is far superior to the ones available over the counter – the jump in the level of cleanliness and comfort for the gums from the electric to this sonic brush is noticeable and remarkable.

4. dpl® Oral Care – LED Technologies

Best For: FDA-Cleared Triple-Wavelength Intraoral Tray – Red + Infrared + Blue, Clinical Heritage, HSA/FSA Eligible

Features: 30 LEDs, triple wavelength – red, infrared (NIR), and blue, intraoral mouth tray format with largest treatment area in its category, FDA-cleared, HSA/FSA eligible, dentist-recommended, 10–16 minute sessions, USB rechargeable, 50+ years of professional light therapy heritage from LED Technologies

Price: $99.00

Amazon

The dpl® Oral Care is the most clinically established intraoral LED tray on this list – LED Technologies has been a professional light therapy manufacturer for over 50 years, supplying clinical-grade devices to medical and dental practices before introducing this home version. Its combination of red, infrared (NIR), and blue light in a single device is the most comprehensive triple-wavelength oral formulation on this list, addressing gum inflammation (red), deep periodontal penetration (NIR/infrared), and bacterial infection (blue) simultaneously in every 10-minute session.

The 30 LEDs arranged across the tray provide what LED Technologies describes as the largest intraoral treatment area of any device in its class – a meaningful differentiator for patients with generalised periodontitis affecting multiple quadrants rather than isolated pocketing. FDA clearance – specifically cleared for improvement of gum health, reduction of gingival bleeding and inflammation, gingivitis, denture-related stomatitis, and halitosis – is the most specific and comprehensive regulatory approval on this list. The device is also one of only two on this list (alongside the Novaa Oral Care Pro) that is explicitly HSA/FSA eligible, making professional-grade oral light therapy accessible without full out-of-pocket cost. The two-year clinical heritage of verified user outcomes – including documented cases of periodontists recommending continued use after patients’ gums stabilised – gives the dpl® Oral Care the strongest real-world evidence base of any device outside Lumoral.

Pros & Cons

Pros

• 30 LEDs – highest LED count of the non-aPDT devices on this list
• Triple wavelength (red + infrared + blue) – most comprehensive single-session coverage
• FDA-cleared with the most specific periodontal indications of any home device
• HSA/FSA eligible – meaningful cost accessibility
• 50+ years of professional light therapy heritage – strongest clinical lineag

Cons

• Specific wavelength nm values not independently published on product pages
• Session time of 16 minutes at maximum – longer than competing devices
• Tray size may feel slightly small for users with larger dental arches

More to Know

Light Type: Red + Infrared (NIR) + Blue | Wavelengths: Red, infrared, blue (specific nm not published) | LED Count: 30 | Session Duration: 10–16 minutes | Warranty: Check ledtechnologies.com | Device Format: Intraoral LED mouth tray

User Patricia W. explains:

Two years ago, two separate dental surgeons advised me to get periodontal surgery. I started using the dpl Oral Care daily alongside oil pulling and electric brushing. About six months after starting this practice, my hygienist noticed my gums had stabilised. Today, after two years of daily use, my gums have not grown back – but they have stopped receding. My dentist said to keep doing whatever I was doing.

5. Starlite Smile Gum Light (Classic)

Best For: Best Budget Plug-In Intraoral LED Device – 32 LEDs, No Charging Ever Required, USB/Phone Compatible

Features: 32 LEDs – 16 red (635nm) + 16 blue (455nm), plug-in design compatible with iPhone, Android, USB, and USB-C (no battery or charging ever required), 2 modes – blue only, or red+blue combined, BPA-free flexible silicone tray, 20-minute sessions, 90-day replacement window, universal tray size, lightweight and ultra-portable

Price: $89.99

Amazon

The Starlite Smile Classic is the most accessible and lowest-friction entry point to intraoral LED therapy on this list. Its plug-in-to-your-phone design eliminates battery anxiety entirely – the device never needs to be charged, never runs flat mid-session, and works instantly with any compatible device the user already carries. For someone new to oral red light therapy who wants to evaluate the category before committing to a higher-investment device, the Classic provides the two clinically relevant wavelengths (635nm red and 455nm blue) at a price point that removes the financial barrier to trying intraoral LED treatment.

The 32 LEDs – 16 per wavelength – provide bilateral coverage of both upper and lower arches simultaneously, and the two-mode design (blue, or red+blue combined) covers the two most important oral health applications: bacterial reduction (blue) and combined anti-inflammatory + antibacterial treatment (red+blue). At 635nm, the red wavelength sits within the most studied therapeutic window for gum tissue repair. At 455nm, the blue wavelength falls in the effective antibacterial range for periodontal pathogens. While the Classic lacks the wireless convenience of the Pro Wireless version and the FDA clearance of the Novaa Oral Care Pro and dpl® Oral Care, it delivers legitimate dual-wavelength intraoral therapy at a cost that makes daily compliance easy to commit to.

Pros & Cons

Pros

• Never needs charging – plug-in-to-phone design eliminates battery management entirely
• 32 LEDs (16 red 635nm + 16 blue 455nm) – highest LED count in the budget intraoral category
• Most affordable dual-wavelength intraoral device on this list
• Ultra-portable – lightest and smallest device on this list
• Universal compatibility – iPhone, Android, USB, USB-C

Cons

• No red-only mode – can only use blue alone or red+blue combined

User Sarah T. explains:

I was skeptical this could actually work but after 3 weeks of consistent use my gums stopped bleeding when I floss – which has never been the case before. It’s the simplest thing to use – just plug into my phone and pop it in while watching TV. I can’t believe how easy it’s been to stick to.

6. Lumoral

Best For: Most Clinically Advanced Home Periodontal Device – Dual-Light aPDT, 2026 RCT Evidence, Deep Pocket Treatment

Features: 48 high-power LEDs, dual-light antibacterial photodynamic therapy (aPDT) – 405nm blue light + 810nm near-infrared simultaneously, requires Lumorinse ICG photosensitiser tablet (dissolved in 30ml water, rinsed for 1 minute before each session), 10-minute treatment cycle, mouthpiece-style applicator covering full maxillary and mandibular arches, used in clinical dental practice, 2026 RCT (HOPE-CP, 200 patients, Journal of Periodontology) – twice as many patients reached healthy gum status vs control, removes 99.998% of harmful bacteria from tooth surfaces and gumline

Price: $265

Amazon

Lumoral is categorically different from every other device on this list – and it’s important to understand why. It is not simply a red or blue LED mouthpiece. Lumoral is the world’s first home-use antibacterial photodynamic therapy (aPDT) device – a technology that has been used in professional dental clinic settings for decades but was, until Lumoral, inaccessible for daily home use. The mechanism involves two steps: first, rinsing with Lumorinse – a solution containing ICG (indocyanine green), an FDA-approved photosensitiser – which binds selectively to dental plaque and periodontal pathogens. Second, the 48-LED mouthpiece simultaneously activates the ICG with 405nm blue light (antibacterial photodynamic action) and delivers 810nm NIR light (deep periodontal photobiomodulation) to the entire oral cavity at once.

The clinical evidence supporting Lumoral is the strongest on this list by a significant margin. The 2026 HOPE-CP randomised controlled trial – 200 periodontal maintenance patients followed for 6 months – found twice as many patients reached healthy gum status in the Lumoral group versus mechanical cleaning alone. A separate published case report documented Stage IV periodontitis (the most severe classification) being brought under clinical control within 5 months of daily Lumoral use alongside scaling. Lumoral also removes 99.998% of harmful bacteria from tooth surfaces and the gumline per session – a bacterial reduction rate that no other home device on this list approaches.

The consumable cost of Lumorinse tablets (an ongoing expense) and the requirement for a preparatory rinse step before each session make Lumoral a more demanding daily protocol than plug-in-and-treat competitors. But for patients with moderate-to-severe periodontitis, active bacterial infection, or a history of failed conventional treatment, Lumoral represents a genuine clinical step-change in home periodontal care.

Pros & Cons

Pros

• 2026 RCT evidence (Journal of Periodontology) – strongest clinical evidence base on this list
• 48 LEDs – highest LED count on this list
• Dual aPDT (405nm + 810nm) – the only device combining photosensitiser-activated antibacterial + deep NIR
• 99.998% bacterial reduction per session – no other home device approaches this
• Used in professional dental practice globally – clinical-grade technology for home use

Cons

• Requires Lumorinse ICG rinse before every session – ongoing consumable cost
• More complex protocol than plug-in LED devices – not the simplest daily routine
• Higher price point with recurring consumable cost
• Not suited for patients with iodine allergy (ICG contains iodine)

More to Know

Light Type: Dual-light aPDT – blue + near-infrared | Wavelengths: 405nm (blue aPDT), 810nm (NIR photobiomodulation) | LED Count: 48 high-power LEDs | Session Duration: 10 minutes (after 1-minute Lumorinse rinse) | Warranty: Check lumoral.com | Device Format: Intraoral LED mouthpiece with photosensitiser rinse system

User Dr. S. Pakarinen, Periodontist explains:

I am absolutely stunned – it is amazing to see the results in the patient’s mouth. The patient’s gums are like new, and gum bleeding has dropped from 25% to 2% at the 3-month follow-up. All deep gingival pockets over 4mm have disappeared.

Buying Guide – Choosing the Right Red Light Therapy Device for Your Gum Disease

Match the device to your gum disease severity: Gingivitis (bleeding, puffy gums, no bone loss) responds well to red + blue LED mouthpieces used consistently – the Novaa Oral Care Pro, Starlite Smile devices, or dpl® Oral Care are ideal starting points. Established periodontitis (deep pockets, bone loss, receding gumline) requires deeper NIR penetration and stronger antibacterial action – the dpl® Oral Care (triple wavelength), Lumoral (aPDT), or Nunawave Oral Care Pro (660nm + 850nm) offer clinically more appropriate wavelength depth for advanced disease.

LED intraoral mouthpiece vs sonic toothbrush – understanding what each does: LED intraoral devices deliver photobiomodulation and/or photodynamic antibacterial action – they reduce inflammation, kill periodontal bacteria, and stimulate tissue repair through light energy. Sonic toothbrushes remove plaque mechanically through vibration. For gum disease management, the most effective protocol combines both – an LED mouthpiece for therapeutic action and a quality sonic toothbrush for daily mechanical plaque control. The NovaaLab Gum Care Sonic Toothbrush + Novaa Oral Care Pro combination mirrors the protocol used in clinical research showing the strongest periodontal outcomes.

Lumoral – who should consider it: Lumoral is the right choice for patients with moderate-to-severe periodontitis, active bacterial infection that has not responded well to conventional treatment, or those who want the most clinically validated home periodontal protocol available. Its ongoing consumable cost and preparatory rinse protocol make it more demanding than plug-in LED competitors – but its 2026 RCT evidence and aPDT mechanism represent a genuinely different clinical category from standard LED devices.

FDA clearance matters for gum disease: For an intraoral device going inside the mouth daily, FDA clearance is the most meaningful safety and performance credential available. Of the LED devices on this list, the Novaa Oral Care Pro and dpl® Oral Care are both FDA-cleared. If regulatory assurance is a priority, start there.

Budget guide:

• Budget (plug-in): Starlite Smile Classic – most affordable dual-wavelength entry point
• Mid-range (wireless): Starlite Smile Pro Wireless – adds wireless convenience + sterilising case
• Mid-range (NIR depth): Nunawave Oral Care Pro – deeper NIR penetration for advanced gum disease
• Clinical-grade: Novaa Oral Care Pro – FDA-cleared, dentist-recommended, best overall
• Clinical-grade triple: dpl® Oral Care – triple wavelength, most comprehensive single session
• Advanced aPDT: Lumoral – most clinically validated, for moderate-to-severe periodontitis
• Sonic complement: NovaaLab Gum Care Sonic Toothbrush – pairs with any LED device above

How to Use Red Light Therapy for Gum Disease – Safe Protocol

Before each session: Brush and floss thoroughly first. LED light therapy is not a substitute for mechanical plaque removal – it is an adjunct to it. Removing surface plaque before your LED session allows the therapeutic wavelengths to reach gum tissue directly rather than being partially absorbed by plaque biofilm. For Lumoral users: rinse with Lumorinse for 1 minute after brushing and before activating the mouthpiece.

Session placement: Ensure the mouthpiece or tray sits comfortably covering both upper and lower gum lines simultaneously. Do not bite down forcefully – gentle jaw closure is sufficient for consistent LED contact with the gingival margin. Most devices include universal-fit trays that accommodate most dental arch sizes.

Session frequency: For active gingivitis or periodontitis – daily sessions for the first 2–4 weeks, then 3–5x weekly for maintenance. Clinical protocols used in peer-reviewed trials use daily treatment during acute phases and 3x weekly during supportive care. Consistency is more important than session length – a 10-minute session every day outperforms a 20-minute session twice a week.

Timeline for results: Reduction in gingival bleeding typically emerges within 1–3 weeks of consistent daily use. Measurable improvement in pocket depth and tissue reattachment requires 4–8 weeks of consistent treatment. Structural gum repair and long-term periodontal maintenance benefits develop over 3–6 months of continued use. Red light therapy does not reverse bone loss – it supports soft tissue health and inflammation control.

Important: Red light therapy for gum disease is a complementary adjunct to professional periodontal care – not a replacement for scaling, root planing, or dentist-supervised treatment. Always disclose use of home LED devices to your dentist or periodontist, particularly before or after any dental procedure.

Conclusion

For anyone managing gum disease at home in 2026 – whether you’re dealing with early gingivitis, established periodontitis, receding gums, or a history of failed conventional treatment – the Novaa Oral Care Pro by NovaaLab delivers the clearest starting point: FDA-cleared, dual red and blue action, dentist-recommended, and backed by a 60-day risk-free trial that removes the financial risk of committing. For users with moderate-to-severe periodontitis who want the most clinically validated protocol available, Lumoral stands alone – its 2026 RCT evidence and aPDT mechanism represent a genuinely different clinical category that no standard LED mouthpiece matches. And for those who want professional-level triple-wavelength coverage in an FDA-cleared tray format with 50+ years of clinical heritage behind it, the dpl® Oral Care is the most credentialled comprehensive option on this list. Whatever device you choose, the evidence is consistent – red and blue light therapy used daily alongside good mechanical hygiene produces meaningful, measurable improvements in gum health over 4–12 weeks of consistent treatment.
