Questionably safe or effective
Questionably safe or effective. The multi spectrum mouth device for oral care is questionably safe. I tried it for two weeks and it increased the sensitivity of my teeth and nerves in my teeth. I cannot explain this. It also caused my teeth afterwards to feel as if they were not meeting together properly. I am senior aged so cannot comment on any therapeutic benefits. I would say use at your own risk. There is insufficient data to prove this device or these light spectrums are truly beneficial and it may be the buyer is the guinea pig. I do enjoy infrared therapy on exterior muscles etc and have used that for years as needed. They were relatively easy to return the item but don't settle for the discounts, insist on full refund.
