Dental Issues

I have been told many times over the years that I have a nice smile but now as I approach the beginning of another decade of my life I can see how time has taken it's toll...this morning I have a dental appointment...for an extraction! I'm not happy.. for some reason the bone surrounding the root of one of my molars ( thank gad it's only one)got reabsorbed and now the poor tooth is hanging by a thread..another space...anybody know a good cosmetic dentist?
