What Is Meth Mouth?
MethMouth is characterized as "rampant decay", resulting from self-destructive behaviors and physiologic conditions caused by meth. MethMouth is not a new disease, and so far there is no research to prove there is a new pathologic mechanism involving MethMouth. MethMouth is a perfect storm of dental disease, where several important conditions that cause dental disease occur at once, and the patient suffers rapid, devastating dental disease.
- Meth causes xerostomia, or "dry mouth", which accelerates tooth decay. Saliva is necessary to dilute and buffer the pH of acid produced by bacteria in plaque. Those with dry mouth should use products available over the counter at pharmacies to replace saliva and reduce decay.
- Oral hygiene often stops during meth use, resulting in a buildup of gooey plaque on the teeth. This plaque is a sticky mass of bacteria and food residue that builds up quickly. Undisturbed by brushing and flossing, the bacteria form mature colonies that are very good at metabolizing carbohydrates. The bacterial waste product is acid that dissolves tooth structure, in turn creating a safe harbor for accumulation of bacteria in a cavity.
- Meth increases the desire to eat foods and beverages that provide energy. Sipping and nibbling junk food and pop creates an oral environment of constant saturation with carbohydrates and acid that cause aggressive tooth decay.
- Meth causes compulsive clenching and grinding of the teeth, known as "bruxing". Bruxing alone causes wear patterns on teeth that resemble facets on a precious stone, can crack and break teeth, aggravate gum disease, and cause TMJ problems. Bruxing on a tooth that has deep decay can eventually break the tooth off.
