If you spend a good amount of time on social media, we’re sure that you’ve seen the new ads out now that promote the “revolutionary” teeth whitening light trays. Many celebrities and influencers have been recommending this product on social media about the magic of the blue light within the past year. But with further research, professionals claim that these light trays may not be the most effective way to whiten your teeth.

Who’s Bright Idea was this?

There are two main product types for at-home light trays, LED (light-emitting diode) and UV (ultraviolet light). The idea of using light to whiten teeth derived from the professional laser procedure. This typically uses a high percentage of hydrogen peroxide gel and a reliable form of laser lighting that must be performed by a dental professional. The take-home trays are supposed to imitate the laser procedure to give the illusion of getting professional treatment.

LED vs. UV light trays

The LED light trays are the least effective of the two and are not as successful at whitening teeth. Former producers of the LED trays, Smile Brilliant claim, “The blue LED lights offered to people for at-home use do nothing to whiten or speed up the price of whitening. This is simply a blue light that does not generate the same UV frequency used in in-office laser whitening.” (
The second option, UV light trays, is more effective, but also more damaging. Smile Brilliant switched to selling UV light trays with a gel solution. The gel’s main ingredient is hydrogen peroxide and claims the UV light causes a stronger reaction of the chemical, similar to the profession laser treatment. But according to the American Dental Association (ADA), there is little research to prove that a UV light can make whitening gel faster and more effective. Not to mention the amount of damage UV radiation can cause.
Most people are aware of how dangerous UV rays are for their skin, but not so much for their teeth. Studies have found that UV light trays can cause significant burns around the mouth, gums, and throat tissue. Some users have even reported the radiation to cause symptoms of their pre-existing health conditions to worsen.
