Teeth Whitening

Teeth whitening is a cosmetic procedure designed to lighten the color of teeth and improve the overall appearance of the smile. This process is performed by removing surface stains and discolorations and, in some cases, may change the natural shade of tooth enamel.

Teeth Whitening Methods:

In-office whitening: performed by a dental professional, involves the application of a light- or laser-activated whitening gel. This method usually provides fast and effective results in a single visit to the dentist.

At-home whitening: A gentler whitening gel, usually based on carbamide peroxide or hydrogen peroxide, is used and applied in a custom-made dental splint. The patient wears the splint at home for specific periods of time.

Peroxide in Teeth Whiteners:

Carbamide peroxide and hydrogen peroxide are the main bleaching agents used in tooth whitening products. They work by releasing oxygen, which penetrates the tooth enamel and breaks down the pigment molecules that cause stains.

Indications for Teeth Whitening:

Superficial stains: Caused by factors such as consumption of coffee, tea, red wine, tobacco or other substances that stain teeth.

Age-related discoloration: Over time, teeth may become yellower or grayer due to enamel wear and changes in the underlying dentin.

Yellowish or gray teeth: Often caused by genetic factors or medications.

Important Considerations:

Before undergoing a teeth whitening procedure, it is advisable to have a dental evaluation to ensure that the patient is a good candidate and has no undiagnosed dental problems. The results of teeth whitening are not permanent and may vary from person to person. The duration of the effect usually depends on factors such as eating habits and oral hygiene.

Post Whitening Care:

After whitening, it is important to maintain good oral hygiene, avoid foods and beverages that may stain, and schedule regular dental checkups.
