Some time ago, Robby was in a snit about having a cavity.
I went to the dentist today, for pain in one tooth being temperature sensitive, and boy was he pissed at me! I have not been to the dentist in 20 years. I had NO cavities. And I've had the low T. thing going on since 1999 or 98...I forget which.
The problem was a hairline crack, which can be crowned. That's what I get for biting into an oyster shell, I guess. Cracked it.
SO, I have to put in my vote that cavities - in my case - are not a problem of low T. levels.
