While I am certainly willing to believe that illicit meth is...bad for you/toxic and the smoke is as well, I'm not finding much to support the idea of it being the primary cause of (or major contributor to) "meth mouth" in a quick search. In contrast, every source I find cites the things the prior poster mentioned as the causes. For example: https://www.drugabuse.gov/publications/research-reports/methamphetamine/what-are-long-term-effects-methamphetamine-misuse https://www.drugabuse.gov/publications/research-reports/meth... > The dental problems may be caused by a combination of poor nutrition and dental hygiene as well as dry mouth and teeth grinding caused by the drug. I would think they would be mentioning that the toxic smoke is a cause or contributor if there was evidence to support it.
