Teeth Whitening: How it Works?

Bleaching is a tooth whitening process where hydrogen peroxide or carbamide peroxide bleaches are used to break stains into smaller pieces. This process disperses color concentration and results in whiter teeth. However, bleaching may not work on teeth discolored by injuries or medications.

What is it?

Bleaching of the teeth is a common technique performed either in a dentist’s office or at home to whiten teeth using peroxide bleaching agents. Depending on where the procedure is performed, and the peroxide concentration of the agent, teeth whiteness and the speed of the procedure can vary.

What should I do to prepare?

If teeth are sensitive, it is recommended to use a desensitizing toothpaste several weeks before bleaching.

What are the risks and potential complications?

There are a few risks and complications associated with teeth bleaching. If a stronger solution with a higher peroxide concentration is placed on the teeth for too long, the tooth may become dehydrated which heightens tooth sensitivity.
