Meth Mouth
Methamphetamine (meth) and crystal meth are popular and highly addictive drugs associated with severe oral health damage. The oral health problems faced by meth users can be the drug’s most noticeable and devastating side effects. These patterns of meth-associated dental decay acquired the name “meth mouth.”
Meth abuse is a national health issue. The American Dental Association refers to the oral consequences of meth abuse, meth mouth, or “crank decay.” From 2004 to 2008, the Substance Abuse and Mental Health Services Administration (SAMHSA) reported on methamphetamine-related emergency department visits. The highlighted negative consequence was serious dental problems, extreme weight loss, and hallucinations.
What Is Meth Mouth?
An effect of meth use is an oral condition called meth mouth, characterized by tooth decay and gum disease. It also may include inflamed gums, receding gums, cracked teeth, and severe cavities. The most common sign of meth mouth is tooth decay.
What Causes Meth Mouth?
Contrary to popular belief, people smoking meth don’t have a higher risk of meth mouth than those who inject or snort the drug. Meth mouth is caused by a mix of bad dental hygiene, poor nutrition, and the effects of meth on a user’s mouth, including dry mouth and teeth grinding.
How Long Does It Take to Get Meth Mouth?
According to the National Institute of Drug Abuse (NIDA), a study found that four years of meth abuse was the time period for an increased risk of meth mouth to develop.
Signs of Meth Mouth
Signs of meth mouth include the following:
- Gingivitis and periodontitis, different forms of gum disease
- Extreme cavities
- Missing, cracked, or fractured teeth
- Black or stained, rotting teeth
- Xerostomia, or dry mouth
- Lesions or burns on the inside cheeks of the mouth or back of the throat
Stages of Meth Mouth
The first stage of meth mouth includes:
- Bad breath
- Red and swollen gums
- Signs of cavities
The second stage involves the following:
- Gums start to recede
- Cavities on teeth worsen
- Oral lesions may begin to appear
The third and final stage of meth mouth includes:
- Missing teeth
- Decayed teeth to the gum line
- Prominent dental lesions
Why Does Meth Ruin Teeth?
Meth causes decreased saliva production, leading to dry mouth and an increased potential for tooth decay. Long-term meth users with poor dental hygiene, especially those who smoke cigarettes and drink alcohol, allow plaque and bacteria to build up, aggravating the effects of dry mouth.
Also continuing to worsen methamphetamine users’ oral hygiene, people addicted to meth typically consume large amounts of sugary drinks to quench their thirst and satisfy a craving for sweets. Additionally, meth use is also associated with lockjaw and teeth grinding and clenching, causing severe wear.
The Methamphetamine Treatment Project (MTP)
To gather research and examine the oral health consequences of repeated meth use in a large clinical study, the Methamphetamine Treatment Project or MTP enrolled participants in the National Health and Nutrition Examination Survey (NHANES).
The main finding was that dental disease was the most common medical co-occurring condition among meth users. On average, methamphetamine users had more missing teeth than anyone in the United States general population. And overall, 96% of the participants had experienced dental cavities or decay, and 58% had untreated tooth decay.
