Tooth whitening is a cosmetic dentistry procedure that lightens teeth and helps to remove stains and discoloration.
It is the most popular treatment by both men and women alike and the treatments available range from one-hour one-time dental visits to take-home do-it-yourself kits.
Tooth whitening is popular because it can significantly improve the appearance of your teeth at much less cost and inconvenience than other techniques.
Types of Tooth Stains
There are two types of staining as related to teeth: Extrinsic Staining and Intrinsic Staining
Exrinsic Staining –
Extrinsic stains are caused by external factors such as coffee, red wine, tea, other dark-colored foods and drinks, tobacco and routine wear and tear.
Essentially they are a natural part of life but they are unsightly and can be removed.
Superficial extrinsic stains can be removed with good hygiene techniques such as regular brushing and dental check-ups with cleanings.
More stubborn stains can be removed with more involved efforts like teeth bleaching or whitening.
Intrinsic Staining –
Intrinsic stains occur much deeper in the tooth than extrinsic stains, forming in the interior of teeth. They can result from trauma, aging,
exposure to minerals (like tetracycline),
during tooth formation and/or excessive ingestion of fluoride.
