Risks and Complications

Teeth whitening is a very safe procedure with many benefits however, like any dental treatment, there are some risks. To ensure you avoid any risks and complications, always have your treatment done under the supervision of a cosmetic dentist rather as over-the-counter products.

Sensitivity is one of the most common side effects of whitening, however this only temporary.

The level of sensitivity can depend on the type of whitening you have. Most people will experience some kind of sensitivity either during and/or after the initial treatment with laser whitening systems. Some people who have laser whitening experience sharp shooting pains in their teeth for up to 48 hours afterwards. Your dentist may offer you a special gel or mouse to apply to your teeth to help reduce some of the pain and sensitivity.

If you are using a professionally supplied home kit you are likely to experience some level of sensitivity to hot and cold foods and even air. If you experience extreme sensitivity it usually means that you are placing too much gel in your trays and wearing them for too long. A lower concentration of whitening gel is available in addition to a desensitising gel, which can be placed in your bleaching trays in the same way as your bleaching gel. The good news is that this sensitivity is totally reversible and will cease when you stop whitening.

To avoid sensitivity you should stay clear of very hot or cold foods for 48 hours after treatment and to maintain the result stay clear of cigarettes and staining foods and drinks. Gums can also become sensitive after teeth whitening, especially if you are already prone to sensitive gums. This will usually occur if the whitening gel comes into contact with the gums and causes irritation.
