Tooth decay is caused by a variety of things; in medical terms, cavities are called caries, which are caused by long-term destructive forces acting on tooth structures such as enamel and the tooth's inner dentin material.

Root canal therapy is a remarkable treatment with a very high rate of success, and involves removing the diseased tissue, halting the spread of infection and restoring the healthy portion of the tooth. In fact, root canal therapy is designed to save a problem tooth; before the procedure was developed and gained acceptance, the only alternative for treating a diseased tooth was extraction.

Some cases of acute periodontal (gum) disease that do not respond to more conventional treatment and self-care such as flossing may require a special kind of cleaning called scaling and root planning. This procedure begins with administration of a local anesthetic to reduce any discomfort. Then, a small instrument called a "scaler," or an ultrasonic cleaner, is used to clean beneath your gum line to remove plaque and tartar.
