Janet I so know how you feel. I hate the dentist!! I have never had good strong teeth. I go in 4 times a year for a cleaning!!! I wish my dentist would just give up the battle, and give me dentures. He won't.
I am so very proud of you for making that first appointment to get it started.
Good luck to you and don't worry! I have had that deep scaling/cleaning done a few times now. A comfy chair and gas!! I wish my dentist was so caring...
