Two years ago one of my fillings came loose. I went to the dentist to have it checked out and he said there was a cavity behind it and I would need a root canal and a crown. I have been reeeeeally busy for the last two years but I can't put it off any longer. I am going in to the Dentist today. I have an extremely high threshold for pain but the minute I get into that chair I turn into a weak little girl. I am going to ask for some good pain pills when he is done!!!
