Tooth bleaching

Tooth bleaching is a cosmetic procedure for whitening the teeth. In principle, it is low-risk and gentle and can therefore be repeated at regular intervals.

The cause of teeth losing their original whiteness over the years is due to both internal and external factors. As we age, by-products of the metabolic process are deposited in the dental matter, causing our teeth to become darker. Discoloration can also be caused by food, particularly tea, coffee and red wine, which, when consumed regularly, lead to visible changes in the color of the teeth.

Teeth can be brightened using hydrogen peroxide or the more commonly used carbamide peroxide, both of which dissolve the discoloration of the tooth matter so it can be flushed out. In-office bleaching uses more highly concentrated chemicals in the whitening process. Thermoanalytic bleaching relies on light and heat to accelerate the whitening process.

The effects of bleaching usually last about a year if the instructions are carefully followed. For the effect of bleaching to last as long as possible, regular cleaning by a dental professional should be carried out. Additionally, good oral hygiene and thorough dental care will extend the life of the treatment. To further support the effects of in-office bleaching, a special whitening toothpaste can also be used. Repeating the bleaching is not a problem.

One of the most common side effects of bleaching is temporary hypersensitivity of the teeth to heat and cold. If bleach comes in contact with the gums or the oral mucosa, slight irritation may occur but will disappear after a few days. The bleaching treatment is not recommended to clients who are allergic to components of the bleaching agent or to clients with pronounced tooth damage (e.g., tooth decay) or gum disease (e.g., paradontosis). Heavy smokers, wearers of braces, and pregnant women are also not candidates for bleaching.
