Side Effects of Teeth Whitening Treatments

The potential side effects of teeth whitening include teeth sensitivity, gum irritation, and ineffective results. However, most patients do not experience any notable side effects from professional teeth whitening, as the dentist can monitor the process and perform treatment in a way that minimizes risk.

Possible side effects of teeth whitening

Dentists take every precaution possible to minimize the risk of teeth sensitivity and gum irritation during treatment. However, side effects can occur in some instances, especially for those that use an over-the-counter whitening kit that is not prescribed by a dentist.

Teeth sensitivity

Teeth sensitivity is one of the most commonly reported side effects of teeth whitening. This can occur if the patient has weakened enamel or if the whitening is not properly administered. In-office whitening is the best way to minimize the risk of sensitivity during and after treatment as the dental professional can apply the bleaching agent in the safest way possible. Dentists often recommend certain treatments before whitening, if necessary, to reduce the risk of sensitivity. For example, dentists may recommend a patient with dental cavities receive dental fillings before the whitening procedure.

Gum irritation

In-office whitening involves isolating the teeth from the gums using a dental dam. This significantly reduces the risk of gum irritation. However, gum irritation can occur if the gums are not properly isolated or if the take-home or store-bought kit is not properly applied. Most patients do not experience any issues with gum irritation, particularly when it is performed in the office and administered by a dental professional.

Ineffective results

It is important to have realistic expectations as to what to expect from treatment. Teeth whitening can remove most minor stains, but it is not effective in treating more severe stains, known as “intrinsic stains.” The dentist can show you on a shade guide the type of results you can expect and go over your alternative options if the ideal results cannot be achieved through teeth whitening.

There are often no side effects

As mentioned, most patients do not experience any side effects from teeth whitening treatments, particularly when it is performed in-office. Before treatment begins, talk to the dentist about ways to reduce the risk of side effects during or after treatment.

The importance of professional treatment

Most people who experience complications from teeth whitening do so by trying store-bought whitening kits. While for some patients they may be useful, they are not nearly as safe or as effective as professional treatment. Instead, it is best to visit a professional for teeth whitening, and the results can last much longer with less of a risk of side effects.
