What is blue light technology for teeth? 

Blue light teeth whitening involves using a specialized blue light source with a teeth-whitening gel or agent. The blue light emits a specific wavelength that activates the whitening formulas, like teeth whitening gel, accelerating the reaction responsible for removing stains and discoloration from your teeth.

What is the purpose of blue light for teeth whitening?

The blue light wavelength is chosen for teeth whitening because it can penetrate the tooth enamel and reach the underlying dentin, where most tooth yellowing occurs. By activating the whitening agent, the blue light intensifies the effectiveness of the treatment, resulting in faster and more evident whitening.

The whitening agent used with blue light technology is usually a hydrogen peroxide-based gel, as it acts as a bleaching agent that breaks down stains and pigments on the surface of your teeth. When exposed to blue light, the hydrogen peroxide molecules become more reactive, allowing them to penetrate the tooth structure more effectively and accelerate the whitening process.

Is blue light teeth whitening permanent?

Blue light teeth whitening is not a permanent solution after one use, so you'll need to use it regularly in your oral care regime to keep up the results.

Does blue light actually work on teeth?

Blue light therapy can show results when used with a teeth-whitening gel or agent after just one use. While the blue light itself does not directly whiten teeth, it acts as a catalyst to accelerate the reactions involved in the whitening process.

To retain the effects of blue light teeth whitening and see the results, it's best used daily as part of your oral health regime. If you don't use it regularly, you won't see the results!

The effectiveness of blue light teeth whitening may vary depending on factors such as the severity of tooth discoloration, the specific whitening product used, and individual variations in tooth enamel. 

Is blue light harmful to teeth?

Blue light used in teeth whitening procedures is not harmful to teeth when used according to recommended guidelines. Our blue light devices are specifically designed for teeth whitening and emit a safe energy level. 

To ensure the safety of any blue light therapy, including blue light teeth whitening, it is always advisable to consult with a dentist who can evaluate your personal oral health and provide personalized recommendations.

What are the benefits of blue light? 

1. Accelerated Whitening 

Blue light acts as a catalyst, speeding up reactions of the whitening formula for faster and more noticeable results than traditional whitening methods. 

2. Quick and easy

Blue light teeth whitening treatments at home are generally quicker and easier than other whitening procedures. Just one use of blue light treatment can significantly improve the whiteness of teeth, reducing the need for multiple, time-consuming treatments at the dentist.

3. Reduced sensitivity 

One common side effect of teeth whitening is tooth sensitivity. However, using blue light during the whitening process has been shown to minimize sensitivity, making the treatment more comfortable, especially for those with already sensitive teeth.

4. Whitening on the go

Some devices, such as our Glow on the Go, include a blue LED light to make it simple to kill bacteria and whiten your teeth while you work, study, or travel.
