I am faced with that same problem, so we have something in common! My decision so far is to have the tooth removed and I am doing that tomorrow. But, I also know that I will have to do something to fill in that gap. I am lucky in that it's in the back of my mouth, but I don't think it will be good to leave that space, so my dentist said it will take 6 weeks for my mouth to heal and I play Scarlett O'Hara ("Gone With The Wind") and "I'll think about that tomorrow."
