Case 1: Discolored front tooth

Before: the upper front teeth, with one front tooth stained a purplish maroon from an old injury
Before
After: the same front teeth after the root canal and internal whitening, the formerly stained tooth now close in shade to the tooth beside it
After

A root canal and an internal “walking bleach” lightened a front tooth that an old injury had stained purple for over two decades.

Case notes by Dr. John Mamoun

This patient had fallen on her front tooth and had been walking around for over two decades with this purplish discoloration of the tooth. The discoloration was caused by internal bleeding when the tooth was injured; the bleeding penetrated into the body of the tooth, staining it a maroon color.

Treatment

Since the nerve of the tooth had died (which often happens with these kinds of trauma cases), I performed a root canal to clean out the nerve of the tooth, disinfect the tooth, and fill the canal of the tooth with a gutta percha filling to prevent further infection.

In addition, to correct the discoloration, I performed a “walking bleach” procedure, whereby a solution of high-concentration peroxide is placed inside the tooth and left there for up to a week. The peroxide oxidized the purple organic matter within the tooth, causing the tooth to dramatically lighten. For decades the patient had been walking around with this discolored front tooth. It took only 48 hours for modern therapeutic science to correct the problem!
