Seems a bit much imo - the cavity specifically won’t harm you and your mouth - but his overall lack of hygiene would be a bit of an issue for me.
Gross, I'd be the same.
I understand! Kissing someone with an infected mouth is gross. Or is his tooth not even smelling or infected
Fun fact, though cavities themselves are not contagious, the bacteria that causes cavities can be passed along through saliva, making you at higher risk of developing cavities once the bacteria is transferred. A big reason why you shouldn’t kiss your kids on the mouth or share silverware when you have an untreated cavity. I’d say it’s your choice on what you’re comfortable with, though!
Getting the cavity filled doesn't change anything. Cavities aren't contagious..
Idt there’s a right or wrong that’s a personal choice a preference. Some ppl that kinda thing it doesn’t bother others it bothers them big time. My mom is big on teeth & them needing to b clean, straight u know properly taken care of. I’d wanna think any normal person would b big on personal hygiene & wanting their partner to take proper care of themselves. I feel like ur fiancé knew these kinda pet peeves about u when u first met & for him to just ignore them now is disrespectful & sign of complacency. How some will let themselves go after they feel comfortable & secure in a relationship. You’re not wrong
