My boyfriend has a teeth fetish?

My boyfriend has a "teeth" fetish. Or maybe it's a cavity fetish. He always wants to look inside my mouth at fillings I've had done, or any dental work, he likes to feel my teeth with his tongue while we're kissing, and he's even asked if he could see copies of my dental x-rays. I care about him and this is the only persistent problem between us so I would really like to find a way to work around this, but it makes me uncomfortable! He is constantly asking me questions about my dental history and wanting to look inside my mouth, and he has made it clear that it's a sexual thing and he's turned on by it. I'm really not sure how to handle this because I've never dealt with anything like this before. Any help?? I'd like educated responses only, please. I understand this is a strange question and am aware that its out of the ordinary, so there's no need for anyone to use the response system to blast their personal feelings/preferences on this topic. Its weird, I get it.

So it's weird. So what? We all have our own little ways of getting turned on. Yes, perhaps your boyfriends is a little further out of the mainstream than most, but if you love him. . . should not matter. Are you guys having sex? I find myself curious how a teeth fetish plays into it. Maybe I'm weird too! The point is, you have a choice to make: can you deal with it, even if it isn't something you're entirely cool with, or can you not? Only you know your threshhold. Think about it, and good luck. :)
