It's been needing to come out for 2yrs, but as normal, I have ignored it. Supposedly the nerve is gone so I was just going to let it be for awhile. However, the tooth seems to have its own thoughts on this and now wants attention. Unfortunately it's bad attention. For the past several months it has given me warnings once or twice a week. Lately, however, it's now down to several times a day and sometimes quite unbearable. So I'm finally giving in and going in tomorrow.
