The most common causes of tooth decay are the effects of:
- tobacco smoke and the intake of various chromogenic compounds (coffee, tea, wine, etc.)
- certain medications
- tooth trauma
- endodontic (root canal) therapies
- the presence of certain dental materials (amalgam, metal pins)
- specific local and systemic health conditions.
Tooth whitening is a non-aggressive aesthetic dental treatment which is performed with the aim of correcting the color of the teeth and giving patients a bright white smile. The most commonly used substances for tooth whitening are hydrogen peroxide and carbamide peroxide, and the two methods imply in-office treatment and at-home whitening approach.
In-office tooth whitening treatment method involves application of highly concentrated agents which is performed under a constant, direct control of the dentist in a dental office. This treatment method assures very good and quick results. At-home tooth whitening treatment method involves making of transparent strips (based on dental impression) in which an individual independently applies tooth whitening agents. The strips are worn for at least four hours or while sleeping, while the results are visible 7 to 10 days after the treatment. This procedure is often performed after the initial dental surgery treatment method.
