When the nerves of teeth die due to trauma or infection, the tooth can gradually become darker over time. This dark color comes from within the tooth and isn’t something that can easily be reversed. Typical teeth whitening treatments do not reach any further than the superficial stains on teeth or very shallow internal tooth stains. Deep stain within a tooth requires an internal whitening procedure to help make the tooth shade match those of the teeth around it.
Teeth that have been traumatized often show symptoms years down the road, when the tooth suddenly begins darkening for no apparent reason. Teeth can also be discolored due to medication that was taken during your mother’s pregnancy or that you took as a small child. Your dentist can treat some of these stains by opening up the nerve chamber of your tooth and whitening it from the inside out.
Internal whitening isn’t always a simple straightforward answer for severe tooth discoloration, but it can be a less expensive treatment to help improve the aesthetics of a tooth, which has lost its vitality. When other treatments aren’t needed, internal whitening can be a more simple therapy for improving the appearance of a single tooth that seems out of place. If internal whitening is not an adequate choice for the patient’s needs, the tooth may be better treated aesthetically with a porcelain veneer or crown.
Only your dentist can let you know if internal tooth whitening is an appropriate option. Each individual is different, as are his or her teeth. Internal whitening is a much more affordable option compared to routine cosmetic treatments that cover the surface of the tooth.
