How Does it Work?

Let’s dive a bit deeper into how the Medex Red Dent X-700 works. This device uses two types of light: red and infrared. These lights are special because they can go deep into your body tissues.

When you turn on the device and put it in your mouth, it sends out light waves. The red light has a wavelength of about 660 nanometers, while the infrared light is around 850 nanometers. These specific wavelengths were chosen because research shows they work best for healing.

Here’s what happens when the light hits your gums:

  • Cell Energy Boost: The light is absorbed by parts of your cells called mitochondria. These are like tiny power plants in your cells. The light makes them produce more energy, which helps your cells work better and heal faster.
  • Better Blood Flow: The light helps your small blood vessels open up more. This means more blood can flow to your gums. Blood carries oxygen and nutrients that help with healing.
  • Less Swelling: The light can reduce inflammation. It does this by changing how certain proteins in your body work. Less inflammation means less pain and faster healing.
  • Fights Bad Bacteria: Some studies suggest that this kind of light can kill harmful bacteria in your mouth. This could help with problems like gum disease and bad breath.
  • Collagen Production: The light may help your body make more collagen. Collagen is important for healthy gums and can help them attach better to your teeth.

Research on red light therapy for oral health is still ongoing, but early results look promising. A study published in the journal “Lasers in Medical Science” in 2019 found that red light therapy could help reduce pain and swelling after dental surgery.

How to Use?

  • Turn on the device
  • Put the silicone part in your mouth
  • Keep it there for 5 minutes
  • Use once a day, any time that works for you
  • Keep using it regularly for the best results

Expert Opinion

A research study by Springer dated 2021 Oct 13 analyzed clinical evidence regarding the DH-alleviating efficacy of LLLT. The immediate, interim, and persistent efficacy results show that LLLT generally alleviated DH in the included studies. Energy density appears to be a critical factor for the successful treatment of DH with LLLT, as higher immediate and interim efficacy was achieved under low-energy–density conditions.
