Methamphetamine, like many other illicit drugs can harm your teeth fairly rapidly.  Back in September, I wrote an article entitled Seven Ways Crystal Methamphetamine Ruins Your Teeth. That article gave seven main ways that crystal meth damages your teeth.

Drug DealThis article, on the other hand, will show you in pictures exactly what methamphetamine can do to your teeth.

FYI, if you have a weak stomach, you may not want to look at the pictures as some may find the teeth a bit gross.

Meth Mouth: The Effects of Methamphetamine On Your Teeth

The picture below is of a patient that came to a dental school who was suspected of using methamphetamine.  All of the brown and dark brown on his teeth are cavities.  The methamphetamine has helped the bacteria in the mouth eat away at the teeth.

The photo below is a close-up view of the left side of the picture above.  You can clearly see that a lot of the tooth structure has been destroyed due to a simple methamphetamine addiction.

Not Just Your Teeth — Methamphetamine Affects Your Whole Body

In dental school, we are learning more about the mouth-body connection.  This article wouldn’t be complete without showing that methamphetamine not only affects the teeth, but it affects the body in many ways.

The diagram below lists about three dozen ways that methamphetamine adversely affects your body, including high blood pressure, heart attack, and kidney damage.

Methamphetamine Effects on Body


Methamphetamine can damage your teeth and create a condition commonly known as Meth Mouth.  Methamphetamine also can damage your whole body in a variety of ways.

Meth Ruins Teeth

Before I came to dental school, I worked at a dental clinic that served those with little or no financial resources.  I remember vividly a young woman in her twenties who had to have all of her teeth extracted.  All of her teeth had extensive decay.  She had used methamphetamine for years before coming to see us.  We were able to make her dentures.  While the dentures worked great, they simply aren’t the same as natural teeth.

Commonly known as crystal meth, meth, crank, speed, glass, or over 100 other different names, methamphetamine can literally ruin your mouth in a very short time.

Seven Ways Methamphetamine Ruins Your Teeth

Blue Crystal Methamphetamine1 – It dries out your mouth. -Methamphetamine directly inhibits saliva flow from the salivary glands.  The saliva offers a lot of protection to the teeth, something I recently wrote about in an article called How Saliva Protects Your Teeth.   In short, when the saliva stops flowing, the teeth are left without many defenses.

2 – Crystal meth gives the user a prolonged “high,” which often causes them to pass out. Meth users have a tendency to pass out frequently.  When they pass out, they are breathing through their mouth, which dries out the mouth.  And without saliva circulating in the mouth, the teeth are at risk.

3 – Meth is acidic by nature. This has been debated.  Some people say that meth isn’t acidic.  Some say it is. Pure methamphetamine is NOT acidic, but most street meth contains acidic byproducts.  For example, the most common method of manufacturing meth in the United States is the Red, White, and Blue Method.  This method of methamphetamine synthesis produces hydroiodic acid.  Other acids can be made as byproducts depending on how the methamphetamine is synthesized.

If only those that manufacture meth knew about the devastating effects of acid on the teeth — they’d probably be sure to only sell you pure methamphetamine!

4 – Meth users clench their teeth a lot. Many meth users are anxious and paranoid, mostly due to the effects of the drug on their body.  When they clench their teeth, they are grinding away valuable tooth structure that has already been weakened due to the other effects of meth mentioned in this article.

5 – Meth gives the user a craving for sugary, carbonated drinks. Since the methamphetamine buydiazepamsite.com dries out their mouth, meth users often try to alleviate this side effect by reaching for soda or energy drinks.  This only adds insult to injury for their teeth, as pointed out in the article Nine Drinks That Can Dissolve Your Teeth.

6 – Meth destroys the enamel. It does this by causing cavities to form and by releasing toxic chemicals that damage the teeth.  In the book Treatment Planning in Dentistry by Stefanac and Nesbit it says:

“Meth mouth” typically begins with the yellowing of the user’s teeth and rapidly deteriorating enamel “flaking” off from the underlying tooth structure. Repeated use of the drug eventually leaves the user’s teeth looking grayish-brown or black stained, decayed to the gum line, and often nonrestorable. The rapid destruction of tooth enamel is thought to be a result of the heated vapors released by toxic chemicals produced while smoking methamphetamine.

7 – Meth Addicts are concerned about how to get their next high, not about their oral health. If you’re addicted to meth, then you probably spend a great deal of time, energy, and money supporting this habit.  Those with addictions of this nature are unlikely to be seeking routine dental care or even brushing and flossing regularly.


Methamphetamine causes significant harm to the teeth no matter how it is taken.  If methamphetamine is smoked, it is much more harmful for the teeth than when injected.  The book Primary Preventive Dentistry by Norman Harris says this about how methamphetamine is used:

It is thought that smokers [of methamphetamine] have worse dental effects, because the chemicals are brought in direct contact with the oral cavity, causing sores and infections. Injectors of methamphetamine do not experience the same severe tooth decay; however, they do experience more severe clenching and grinding. The increased bruxism is attributed to the more powerful effects of the injected drug.

If you or someone you know is addicted to methamphetamine, try to get help as soon as possible.  Methamphetamine doesn’t just affect the teeth, it affects the whole body.

Here’s a good article from Minnesota Public Radio about Ryan Hintz, a recovering meth addict, about how he is overcoming the addiction.
