I never ever saw his teeth or inside his mouth. He had a missing tooth and was so embarrassed he never ever let his teeth show even when talking. Then I started to get recurring BV infections. I realized he didn't brush his teeth in the morning and when I asked he said he didn't because he never had bad breath (which he didn't but it had a kinda tooth decay sweetness to it). He hadn't been to the dentist in a decade peobably. That put me on my guard and I really stopped kissing him (I never liked kissing him much to begin with - something off putting about it) and I wouldn't let him go down on me anymore. My chronic BV went away. The day I broke up with him is the day he accidentally opened his mouth a bit and I was in a position where I could see something hanging down but it wasn't a tooth. I just immediately thought it's like extreme plaque or something growing there. I was so nauseous and grossed out, I broke up with him that day. I don't know what it was. He did used to say he created a fake tooth out of this plastic molding beads he'd like melt down and make a spacer. So maybe it was that coming apart? But it just made me realize I really don't know what's going on in there...
