Tooth discoloration can be caused by a variety of internal and external factors. Common everyday products such as tea, coffee, red wine and cola can cause brownish stains on teeth depending on the frequency of exposure and the amount you’re exposed to. Prevalent tobacco use can also lead to tooth discoloration. Typically external staining can be reduced by home bleaching or in-office tooth whitening.
Discoloration can also be caused by internal issues, including tooth trauma, decay and cavities. In the case of trauma, a single tooth or several affected teeth may end up noticeably darkened over a period of time (months or several years) because of blocked or damaged blood vessels. This type of staining can be reversed in some cases by internal bleaching (after a root canal is completed to remove the dead blood vessels).
Staining can also occur from taking tetracycline (an antibiotic) during the development of your teeth or if your mother took tetracycline during her pregnancy. This type of staining cannot be reversed by bleaching, but there are several options available to whiten your smile.
