How Does LED Teeth Whitening Work? A Complete Guide
If you’re searching for a safe, effective way to brighten your smile, LED teeth whitening has become one of the most popular cosmetic dental treatments in Toronto. But how does it actually work—and is it worth it?
At The Lab Skin Science, LED teeth whitening is a non-invasive, professional treatment designed to deliver visible results in a single session, without the sensitivity often associated with traditional whitening methods.
What Is LED Teeth Whitening?
LED teeth whitening is a professional whitening treatment that uses a hydrogen peroxide or carbamide peroxide gel, activated by a specialized LED light, to lift stains from the enamel and dentin layers of the teeth.
Unlike over-the-counter whitening strips or trays, LED whitening is performed under professional supervision to ensure both safety and effectiveness.
How Does LED Teeth Whitening Work?
LED teeth whitening works through a simple but powerful process:
1. Whitening Gel Application
A professional-grade whitening gel is carefully applied to the teeth. This gel contains active whitening ingredients that target deep and surface stains.
2. LED Light Activation
An LED (light-emitting diode) lamp is positioned over the teeth. The LED light accelerates the whitening reaction, helping the gel break down stains caused by coffee, tea, wine, smoking, and aging.
3. Oxygen Release
When activated, the whitening gel releases oxygen molecules that penetrate the enamel and lift discoloration—without damaging the tooth structure.
4. Immediate Results
Most clients see their teeth lighten by several shades in one appointment, with results continuing to improve for up to 48 hours.
Is LED Teeth Whitening Safe?
Yes—when performed by trained professionals. At The Lab Skin Science, treatments are carefully customized to your enamel condition and sensitivity level.
Benefits include:
Non-invasive and painless
Minimal to no sensitivity
Safe for enamel when properly applied
Suitable for most adults
This makes LED teeth whitening an excellent option for first-time whitening clients.
What Stains Can LED Teeth Whitening Remove?
LED whitening is effective at reducing:
Coffee and tea stains
Red wine discoloration
Tobacco stains
Yellowing from aging
Food and beverage pigmentation
While LED whitening does not change the color of crowns or veneers, it significantly improves the natural shade of your teeth.
How Long Do LED Teeth Whitening Results Last?
Results typically last 3 to 6 months, depending on lifestyle habits and oral care.
To maintain your brighter smile:
Avoid staining foods for 24–48 hours
Practice good oral hygiene
Schedule touch-up treatments as recommended
The Lab Skin Science also offers maintenance options to help prolong your results.
