How do i get my boyfriend to take care of his teeth?

Your choice: I don't think you can force him to take care of himself. If you don't mind dealing with a guy with rotten teeth and bad breath, its your choice. If it does bother you, then express your concerns... Make it his choice to keep or loose you as his girlfriend. All the best to both of you.

Keep your teeth: Or lose it! this is a touchy situation but a communication of love and concern can catch an attention. Well, not the way i said it though :). Some articles about communication recommended to start by saying, " i feel...", "it worries me", ..Instead of starting with "you", that can implicate judgement and can be accusatory for this matter...There's no enough space to dissect this matter...
