How does the Whitening Blue LED light work?

Updated 1 year ago by Atul Shastry

Is it safe?

Yes, our whitening blue light LEDs are completely safe to use and help whiten your teeth faster.

How does teeth whitening work?

All teeth whitening products make use of either of these two methods to bring out brighter smiles:

  1. Chemical Action — Products that employ a chemical action of whitening make use of bleach to chemically remove stains on teeth. Typically bleach is used in whitening trays, gels, or strips.
  2. Physical Action — Products that employ abrasives (as found in toothpaste) to physically scrape the stains off of your teeth. These products are typically whitening toothpaste that aid in the physical removal of stains.

How do blue LED lights help with teeth whitening?

Whitening products that apply the chemical action (such as whitening gels or strips) have either hydrogen peroxide or carbamide peroxide as their key ingredient. Think of it as a bleaching solution for stained teeth.

The oxygen molecules in the peroxide solution stick onto your teeth and effectively lift yellow stains off the surface. Exposing that bleaching solution to blue LED lights increases the rate the oxygen molecules interact with your teeth, consequently speeding up the stain-lifting reaction and allowing for whiter teeth at a faster rate.

Does light treatment whitening actually work?

Teeth light whitening methods researched by both the Journal of American Dental Association as well an independent study from the American Chemical Society revealed that LED teeth whitening lights provide results for a whiter smile.
