Thanks for the info. I think I will call our research nurse (for the clinical trial of chemo-prevention he is in) and talk to her. Then I might call the dental oncologist we had at MD Anderson. Kelly really liked him and they should still have his xrays and all to look at the tooth I am talking about. Since it was a baby tooth it had very small roots going down anyway, but they said from one xray to the next, the roots it did have are almost completely gone and there is a black spot under it. What they were talking about doing sounds like what you said. Putting something down into the bone and waiting for about 2 months till it healing and then attaching a fake tooth.
Thank you again for your help. You are a life light that I feel is always burning bright when I think I am getting lost on this journey of ours. I really appreciate all the hard work you do with this forum and everything else.
