How Meth Affects Your Teeth

Why Does Meth Rot Teeth?

According to the American Dental Association (ADA), meth mouth refers to severe caries associated with use of methamphetamine. Meth mouth is also called “crank decay” and can resemble early childhood caries.1

Not only is the drug bad for oral health, but its use also leads to users neglecting their hygiene, which exacerbates dental problems. 

Methamphetamine causes extensive tooth decay by damaging the tooth enamel. The drug decreases saliva production, which leads to dry mouth and an increased risk of cavities. Its use also causes other oral health problems, such as gum disease and mouth sores.

Nutritional Effects of Meth 

Meth can increase cravings for foods that are bad for dental health, including sugary treats. 

In general, meth users tend to make poor dietary choices. This increases their risk of developing cavities and other dental hygiene problems. Such diets lack proper nutrition, including vitamin C, calcium, and iron, to support good dental health. 

Lack of nutrition also slows healing. Mouth sores and lesions, which are common in meth users, usually take longer to heal.

Meth also increases the likelihood to grind or clench teeth. This is due to nervousness and anxiety that often accompany meth use. These practices wear down already sensitive teeth.

What are the Early Signs of Meth Mouth?

Tooth decay is one of the first signs of meth mouth. 

Most meth users develop stained teeth and mild to moderate dental health problems shortly after they begin using.

Other early signs of meth mouth include: 

  • Cavities
  • Bad breath
  • Missing teeth
  • Bruxism (teeth grinding)
  • Gum disease

General signs of meth use include:

  • Weight loss
  • Skin sores
  • Changes in mood and behavior
  • Insomnia
  • Isolation

Treatment for Meth Addiction

Recovery from methamphetamine addiction is difficult. There are many different types of addiction treatments available. The best approach varies by person. 

Tapering meth use is one of the most effective options. Medical detox is also beneficial. Both inpatient and outpatient meth abuse treatment programs are available. 

Inpatient treatment centers offer a variety of services such as: 

  • Individual counseling
  • Group therapy
  • Family support
  • Medical detoxification
  • Access to 12-step programs

These services help someone recover physically, mentally, and emotionally from addiction. 

Aftercare is also an important part of treatment. Relapse prevention programs help people stay sober after initial treatment. 

Some people also benefit from medication during meth withdrawal and recovery. There are no medications specific for meth treatment, but several pharmaceutical options are available for easing withdrawal symptoms. 

If you or someone you know is struggling with meth addiction, help is available. Contact a professional treatment center to learn about treatment for substance abuse.
