Methamphetamine use linked to tooth decay: “The growing use of highly addictive methamphetamine throughout the country is creating a prominent scar on an increasing number of users – rotting, brittle teeth that seem to crumble from their mouths.

Methamphetamine can be made with a mix of substances, including over-the-counter cold medicine, fertilizer, battery acid and hydrogen peroxide.

Together, the chemicals reduce a user’s saliva, which neutralizes acids and physically clears food from the teeth, said Dr. Eric Curtis, an Arizona-based spokesman for the Academy of General Dentistry.

‘When the saliva isn’t flowing, the bacteria build up a lot faster,’ said Dr. Darrell Morton, an Atlanta dentist.

Meth users also may neglect their teeth, or moisten their dry mouths with high-sugar drinks, and anxiety caused by the drug prompts them to grind their teeth, which speeds decay.

The problem is particularly noticeable among inmates, whose oral problems have some prison systems struggling to provide dental care.” (San Diego Union-Tribune)
