One time, I had kinda an uncomfortable feeling on one side of my mouth, told the dentist so, and they did bitewings etc...everything looked "normal" they said. It had been 6-7 years w/o a checkup (groan...I know....) so I was surprised when I didn't have any cavities. Six months later, go back, get cleaned, everything "ok", six months later...when xrays are ok...three teeth all in a row, cavities! Like, the teeth infected each other. I was pissed. I thought the dentist did it on purpose to make more money. I know, that's kinda conspiracy theory-ish isn't it? To this day, I don't trust dentists. Because how do you prove anything different than what they said? I love my current dentist, I loved my previous dentist, but still...I'm like...I go from zero cavities to 5 or six?
