Light Emitting Diode, or LED, is a type of light that can be used to accelerate the process of teeth whitening. A gel solution is placed into a mouth tray that fits over your teeth, and then the LED light shines on the teeth and activates whitening agents in the gel.
There are two different types of whitening agents used. Bleach-based solutions usually contain hydrogen peroxide or carbamide peroxide, which remove stains on and below your teeth’s surface. And non-bleach products work on surface stains only. The type of ingredients and their strengths vary among products.
You can opt to have LED whitening treatments applied in-office by your dental professional, or buy LED whitening devices from your dentist or over the counter. While in-office treatments are stronger, at-home LED whitening devices like Colgate® Optic White® ComfortFit LED Teeth Whitening Kit offer rapid. You only need to wear the comfortable, flexible LED device for 10 minutes a day, with results visible in as little as three days.
