Hydrogen Peroxide Teeth Whitening Gel Application

In general, only a small drop of the teeth whitening gel should be placed on the inner front part of the tray per tooth. It is often only recommended to bleach the visible front teeth. Next, insert the trays and press firmly against your teeth. Quickly wipe off any excess gel from your gums to avoid irritation and be careful not to swallow any of the solution. Leave the trays on for no longer than the recommended time, which can differ based on the type of whitening and manufacturer. Once the time is up, remove the trays and thoroughly rinse your mouth. Clean your whitening trays and store in a cool dry place.

Potential Side Effects and How to Mitigate Them

Like any procedure, there are potential side effects. Common side effects include tooth sensitivity to cold, hot, or sweet foods and beverages, and gum irritation, which tend to go away when teeth whitening is discontinued.

Luckily, your risk of experiencing these symptoms can be reduced. One of the best ways to lower your risk of experiencing side effects from teeth whitening is to see a dental professional before teeth whitening. Your dentist will ensure that you are a candidate for teeth whitening and can offer the best guidance for safely whitening your teeth. In addition, regularly using a toothpaste that contains fluoride treatment and is geared to provide relief for sensitive teeth can help mitigate tooth sensitivity from teeth whitening.

If you experience discolored gums or gum soreness after a whitening procedure, it is important to follow up with your dentist. Protective gels or covers can be used over the gums to prevent bleaching material from contacting the gums. Be sure to only apply the recommended amount of whitening solution to your teeth to avoid damage to your teeth and gums.
