In need of examination, cleaning, periodontal, bone grafts and crowns to keep my teeth. One dentist told me back in 2009 that I might need a root canal- I might on one tooth, but I don't know what tooth that is. My lower front teeth are getting looser because of bone and gum loss. I had poor dental care in my childhood, so I am suffering some of the consequences now- I need at least 3 crowns, POSSIBLY 3 places for bone and periodontal grafting. I am trying to keep my teeth, and haven't had an exam since RAM came here in April 2010, and they could only do ONE thing. So I got my teeth cleaned, even though I didn't get x-rays, So I really don't know whether I need fillings (I was told I needed at least 3 back molar crowns years ago), root canals, or what. My primary concern is the periodontal work and crowns so I can keep my teeth- I have 2 cracked molars.
