Well, I mean, you normally swallow pills rather than chew on them, right? Even then, not sure how they managed to crack the teeth of an animal with a much stronger bite force. The advice is solid though. My first year of work had me doing six days a week and full-time college. I completely forgot to take care of my teeth during this period and ended up with terrible cavities. Didn't even realize it until the start of the new year when my hours were temporarily cut and I had time to relax. I've not done anything to professionally fix them. Instead, I leave them as a reminder to take better care of my teeth going forward. More sensitive to cold food now but otherwise they will only ache IF I stop flossing them regularly.
