Feature: 1. Whitening principle: By using surface nanoparticles and photolysis, it activates the most H2O2 at low or room temperature, generating a large number of oxygen atoms to penetrate the teeth and decompose the color molecules to achieve the effect of teeth whitening. 2. COLD BULE LIGHT: 10 LEDs irradiate high strength blue cold light with an output power of 6000MW/CM. It is recommended to irradiate 2 ~ 3 times per session, 10‑15 minutes each time. 3. WIDELY USED: Teeth bleaching light effectively improves tooth discoloration caused by smoking, coffee, tea, red wine, etc. Or congenital, genetic and drug induced discoloration. 4. FLEXIBLE ROD: Teeth bleaching lamp with a flexible extension of the tube, you can choose different angles at will, stable and durable, lightweight and portable, easy to use. 5. SAFE RELIABLE: LED teeth bleaching light is a safe and reliable method of teeth whitening with low heat and even light that does not alter the dentin structure.
