It'd be quite funny to live in a future where cavities don't exist, but breathalysers are useless. (without rinsing your mouth out first, I guess) Hopefully it doesn't dry out gums and cause gum disease.

The article extensively talks about the amount produced. While it has not been tested against breathalyzers, it is producing so little alcohol that it seems unlikely to be a problem. The claim in the article is that, across 24 hours, you might consume a few miligrams of alcohol, as compared to "if you swallowed 1/10th of your mouthwash, that would be ~200 milligrams of alcohol". So across the entire day, you are producing a couple orders of magnitude less alcohol than is in 1/10th of a mouthwash treatment (or 1/5th I guess if you use it twice a day).
