I recently realized my husband goes multiple weeks at a time without brushing his teeth

When I met my husband, one of the first physical things I noticed about him was that he does not have nice teeth. They are super crooked and at the time I met him, they were kind of yellow but not terrible. He’s good looking in other ways, but his teeth are truthfully among the worst I’ve seen. I feel bad even writing this. I take good care of my teeth and suffered through 8 years of orthodontia as a kid.

I didn’t live with my husband before we were married. When we first moved in together, I didn’t notice anything out of the ordinary about his oral hygiene habits. My husband says that his teeth are really yellow because he has weak enamel. I did notice that he would go longer than I’d be ok with skipping brushing but nothing super alarming.

Over time, I noticed that it seems like he’s given up on brushing his teeth. Last year he stayed at a family members house for a week and did not pack his toothbrush. I know that he didn’t get a new one while he was there because he didn’t bring a new one back and he only will use one specific kind of toothpaste, which I’m certain his family members don’t use (I’ve been in their bathroom where he stayed). That seemed pretty gross to me, but I tried not to think too hard about it. That was about 6 months ago.

About 2 weeks ago I noticed that he was out of his toothpaste. He made a comment about having to use mine and how much it upset his gums. I know for a fact he only used my toothpaste once. I’ve been facing it in a very particular position so that I can notice if he’s used it or not. I also feel his toothbrush sometimes to see if it’s wet and it never is. I’ve noticed at times that he has bad breath but we aren’t a super touchy feely couple. We’re at a bad place in our relationship due to other things so we aren’t really physical right now, we’re in the roommates phase. His teeth are super yellow now after several years of completely neglecting his oral hygiene. He hasn’t been to the dentist for a cleaning in more than 5 years. I feel like a terrible person for admitting this, but I’m physically repulsed by the thoughts of kissing him now. I still love him as a person, but I’ve lost a significant amount of my attraction to him. I know I mentioned that I noticed his crooked teeth, I never really cared but it wasn’t something that was attractive to me. It was just something that was part of him. But the complete neglect of hygiene is really putting me off. He’s extremely sensitive and I don’t know how to address this with him. It will likely hurt his feelings and not result in any change or action being taken. His hygiene is good in other ways. He showers, washes his clothes, gets haircuts, etc, it’s this one specific thing that he’s apparently given up on. I really would like to bring it up in a way that won’t hurt his feelings, but he’s so incredibly sensitive so I guess I’ll stick to venting
