I don't think it's widely accepted how much oral health has to do with the rest of your body, and I totally have the teeth of a dude who has been in bands for twenty years!
My B.I.L. is a dentist and he was the one that suggested treating my tooth, whether it was just an ear infection that cleared up because of the Amoxicillin I had to take before I could have my root canal, or if indeed it was connected, I haven't had the problem arise since then.
BTW I'm not a dentist or a doctor, and I don't know S#!t.
