Meth Mouth - How Methamphetamine use affects your mouth.

Various reports link the tooth decay associated with meth to the acidic and corrosive effects of the chemicals found in the drug, such as anhydrous ammonia (found in fertilizers), red phosphorus (found on matchboxes) and lithium (found in batteries), which when smoked or snorted might erode the tooth's protective enamel coating; however, it's more likely that this degree of tooth decay is brought on by a combination of drug-induced mental and physical changes resulting in xerostemia (dry mouth), extended periods of poor oral hygiene, frequent consumption of high calorie, carbonated beverages and tooth grinding or clenching.

Some users describe their teeth as blackened, stained, rotting, crumbling or falling apart. The extent of tooth decay varies widely among meth users. Studies have found that users who snorted the drug had significantly worse tooth decay than those who smoked or injected it, although all types of users suffered from dental problems. Often, teeth cannot be saved and must be removed.

If you use methamphetamine or know someone who does, a visit to a medical doctor and a dentist is recommended as soon as possible.
