Teeth Whitener Gels are a popular dental product that can help to remove surface stains and brighten up your smile. These gels are typically applied to the teeth using a special tray or applicator and left on for a specified amount of time. They work by using a peroxide-based formula to break down stains and whiten teeth. Many people find that whitening gels are an effective and affordable way to improve the appearance of their teeth, without the need for expensive dental treatments. However, it's important to follow the instructions carefully and seek advice from a dental professional if you have any concerns.

Frequently Asked Questions (FAQs)

1. What teeth whitening gel do dentists use UK?

One hydrogen peroxide-based product many dentists prefer is Opalescence Boost. The main ingredient in Opalescence Boost is a gel that contains roughly 38% hydrogen peroxide.

2. Can you put teeth whitening gel directly on teeth?

Don't over think it. Keep in mind your only concerned about the front surface of your teeth which means there is no need to waste whitening gel on the back side. With that in mind use the gel sparingly and only apply it to the portion of the whitening tray that comes in contact with the front surface of your teeth.

3. What is the gel in teeth whitening?

The active ingredient in whitening gels is hydrogen peroxide, which removes stains and is then safely absorbed by the body. Most over the counter whitening products use low concentrations of hydrogen peroxide, while cosmetic dentists use higher concentrations to get faster, more effective results.
