I'm 37 and the only time I ever had a cavity, it was a small one when I was 29. I experienced intense pain and then numbness in my face as the plane I was on was landing. My mouth felt normal like 20 minutes after landing. I suspected a cavity, did some googling, went to a dentist and got it filled. That was the first time I had been to a dentist in over 5 years. I figured I should use my dental insurance and start going in for cleanings regularly. So I did that for a bit, then covid happened. I haven't been to a dentist since 2019 and my teeth seem fine. I usually brush twice a day, but sometimes I fall asleep on the couch and miss brushing. Sometimes I'll go a month without flossing, but usually floss every other day. I have some dental picks I use regularly. Orbit gum is chewed pretty often. But yeah I think it's gotta be genetic or something.
