What Are Teeth Whitening Lights?
Teeth whitening lights are special devices that make teeth whitener work better. They come in two main types:
- LED lights – These are safe, cool, and OK for home use
- UV lights – These work fast but can be too hot
The light helps the whitening gel work faster on your teeth. It makes the gel break down stains from coffee, wine, and smoking.

Whitening lights help the hydrogen peroxide in whitening gel work better. Here’s how:

- The gel breaks up stains
- Your teeth look whiter
LED teeth whitening kits work best on surface stains. They don’t work as well on deep stains from:
- Genetics
- Some medicines
- Very dark stains
For best results, use gel with 10%-35% hydrogen peroxide. This helps get dental-grade results at home.

Are whitening toothbrushes with lights effective?
They help a little with surface stain removal but aren’t as strong as real whitening kits.
Can I use whitening lights if I have braces?
It’s best to wait until after braces come off. Using whitening with braces can make teeth look uneven.
