What Is Meth Mouth? Causes, Statistics, and Effects

Methamphetamine, or meth, is a highly addictive stimulant that has many potential long-term effects, including stroke and permanent brain damage. It also has a devastating effect on dental health, leading to the term “meth mouth.”
Meth mouth is the result of acidic tooth decay and drug-induced physical changes that occur with meth use, leading to tooth decay, gum disease, and damaged or lost teeth.

Meth mouth is one of the most recognizable physical changes with long-term meth use. It includes severe gum disease and tooth decay, often causing the teeth to crack, break, or fall out.[1] The teeth of people who use meth chronically are often stained, rotting, crumbling, blackened, or falling apart.
The effects of meth mouth are caused by physiological damage, such as dry mouth and malnutrition, and drug-induced psychological effects, such as long periods of poor oral hygiene.

The signs of meth mouth can include:

  • Dry mouth
  • Cracked teeth
  • Loose teeth
  • Missing teeth
  • Lockjaw
  • Carious lesions (micro-cavities)
  • Gum disease
  • Teeth grinding (bruxism)
  • Black teeth
  • Bad breath[2]

Causes of Meth Mouth

Meth mouth is common with people who use meth, but it can have multiple causes.[3] People who are addicted to meth tend to neglect their hygiene, forgetting to brush their teeth for long periods. They also have poor nutrition habits and may go long periods without eating or combine sugary foods like sodas and candy with meth.
Smoking meth also contributes to cavities and tooth damage. Left untreated, this can cause abscesses, severe decay, and nerve damage. The stimulation from meth can cause teeth grinding or clenching that damages the enamel and weakens the teeth, making them easier to break or decay.

Some chemicals found in meth, such as drain cleaner, antifreeze, and battery acid, can corrode the teeth. Another factor is xerostomia, or intense dry mouth, which saps the saliva that’s crucial to wash away bacteria. Without eating a proper diet, the body’s ability to heal is impaired, which further affects dental health.

Statistics on Meth Mouth

According to a study in The Journal of the American Dental Association that examined the mouths of 571 people who use meth:

  • 96% had cavities
  • 58% had untreated tooth decay
  • 31% had six or more missing teeth[4]

The study also found that the more meth a person used, the worse their tooth decay was. People over the age of 30, women, and cigarette smokers were more likely to have tooth decay and gum disease.

Other Effects of Meth

Aside from meth mouth, using meth can have short- and long-term adverse effects.
The short-term effects of meth include:

  • Shortness of breath
  • Nausea
  • Vomiting
  • Diarrhea
  • Hyperactivity
  • Insomnia
  • Decreased appetite
  • Tremors
  • Trouble breathing[5]

The long-term effects of meth may include:

  • Irregular heartbeat
  • Stroke
  • High blood pressure
  • Violent or aggressive behavior
  • Confusion
  • Anxiety
  • Paranoia
  • Hallucinations
  • Delusions[6]

What Are the Treatment Options for Meth Mouth?

The treatment for meth mouth depends on how severe the damage is. Meth mouth is irreversible, so the treatment is focused on repairing the damage and mitigating the effects.[7]
Depending on the level of damage and decay, people may need tooth extractions to remove unsavable teeth. Dental implants, bridges, or dentures may be necessary to reconstruct the mouth for a better appearance and function.

Less severe cases may need cavities filled or root canals to address decay, as well as treatment for mild, moderate, or severe gum disease. Gingivitis, the first stage of gum disease, can be reversed with proper oral hygiene. More severe gum disease causes permanent damage, such as gum recession, periodontal pockets around the teeth, and tooth and jawbone loss, so the focus is on mitigating the effects.[8]

Treating the Addiction

Treating the oral health effects of meth mouth is only part of the challenge. The addiction needs to be addressed to ensure that meth mouth doesn’t worsen and that the person has good oral hygiene moving forward.
Though stimulant withdrawal from drugs like meth isn’t usually life-threatening, it can be extremely unpleasant. The symptoms can vary but generally include:

  • Fatigue
  • Anxiety
  • Lack of energy
  • Weight gain
  • Irritability
  • Dehydration
  • Chills
  • Insomnia
  • Dysphoria
  • The inability to think clearly
  • Anhedonia (loss of the ability to feel pleasure)
  • Social withdrawal
  • Drug cravings[9]

Many of the withdrawal symptoms subside over days or weeks, but cravings can last for long periods and increase the risk of relapse.

Medical Detox for Meth

Medical Detox for Meth

Meth withdrawal management is key to clearing the drug from the body while managing the unpleasant symptoms of withdrawal. This involves a controlled, supervised setting with a medical team to monitor withdrawal symptoms, provide medications as needed, and prevent complications.

Once detox is complete, it’s highly recommended to enter an addiction treatment program in an inpatient or outpatient setting. Each treatment plan is individualized but may include a combination of individual therapy, group therapy, behavioral therapies, and holistic therapies. The goal of these treatment sessions is to address the underlying causes of addiction and develop better coping strategies and stress management techniques to support long-term abstinence.
