How I Prevent Meth Mouth

Oral health is very important, especially if you regularly smoke. While tobacco is the most commonly smoked substance, other substances, with varying degrees of harm, can also be smoked. One such substance is crystal meth, which is notoriously associated with a condition known as “meth mouth”, which is characterized by tooth decay and advanced periodontal disease. While this is a severe and possible outcome of meth use, taking proper measures can reduce your chances of developing it.

Contrary to what many think, you can't only get meth mouth if you smoke it. You can develop it no matter what route you choose to administer the drug. This comes as a result of the dry mouth, vasoconstriction, and tooth grinding meth causes. Add in infrequent oral hygiene, poor dietary choices and meth's caustic nature and you have a recipe for disaster. It doesn't help that there is a huge stimgma attached to meth users, especially those who have dental issues. This stigma can make people hesitant to get dental treatment, which in turn worsens their condition.

As a methamphetamine user, I've managed to maintain pretty good oral hygiene. I have no cavities but I do have a mild case of gingivitis. Quite good for a habitual user. This is a result of flossing regularly, rigorously using biotene and alcohol-free antiseptic mouthwash, and frequently brushing with Prevident or toothpaste with stannous flouride.

So, what's the ultimate way to avoid "meth mouth"? take care of your fucking teeth. Brush and floss regularly. Ask you dentist for prevident. If you don't have it, use toothpaste with stannous flouride. I used Crest Pro-Health prior to getting Prevident. I use an alcohol-free antiseptic mouthwash and I floss somewhat regularly. The best order is: floss, mouthwash, brush. Do this at least twice a day and your chances of getting periodontitis go way down.

Lifestyle changes can also help improve your oral hygeine. Eat whole foods with minerals like calcium, drink plenty of water to deal with dry mouth, and reduce sugar intake. For example, if you love soda, go for a zero sugar or diet alternative. When smoking, put the end of stem behind your teeth so that the caustic smoke doesn't get on your teeth. The best practice is to brush your teeth or use mouthwash after every smoke sesh. But you aren't gonna be carrying around toothbrush when going to smoke with other people, so make sure to brush regularly.

I don't make the best lifestyle choices, especially when binging, but I do brush my teeth on a regular basis. As a result, my teeth look indistinguishable from that of a non-user. And if you also take this advice, you too can prevent the development of "meth mouth"
