I haven’t read the specific studies. I practice in an area with a more-affluent, educated, and elderly patient base. I haven’t seen any cases of meth mouth. The closest that I’ve seen was an exact replica of “meth mouth” in a young adult on Ritalin. The only two causative agents that I could guess at were: 1) dry mouth from the Ritalin, and 2)constant night-time snacking because she would sometimes go days without sleeping.
Interesting. Thanks!
