Intrinsic vs. Extrinsic Stains

Riverwalk Dental provides patients with tooth whitening treatments, but which kind of treatment is appropriate depends on the nature of the stain. If a stain is on the outside of the tooth or just slightly below the surface, it is called an extrinsic stain. But a stain could also be caused by damage to the pulp of the tooth, in which case it is called an intrinsic stain, and treating it could be more complicated.

Any kind of stain can be masked with a veneer or bonding. Since extrinsic stains are acquired from exposure to tar or dark liquids, dentists usually simply bleach them, but that won’t work on an intrinsic stain. Furthermore, damaged dental pulp might indicate a continuing infection which would threaten the patient’s health and comfort. Other possible causes include an excessive amount of fluoride exposure and the use of certain antibiotics, but we’ll need to use our imaging systems to determine whether a root canal or replacement of the crown is necessary. If there is no ongoing threat to the patient’s health, concealing the stain may be all that is required.
