Teeth are important. To me, they are a deal breaker.
I have all my teeth. I take care of my teeth. If you don't have your own teeth due to accident or other issue, you need to go to a dentist & have them hook you up. They do it every day.
I have met alot of guys lately who have regular full time jobs, and are missing teeth. WHY are they not going to a dentist?? They have medical coverage at the job.
I am sorry, but i am not gonna make out with you if you don't have any regard for your oral hygiene. It makes me wonder what else you are very lax about if you can't handle something that prominant.
