God, bless my dentist!

God, bless my dentist for her patience... She really was trying to do her best. We spent 2 hours trying to fix my tooth.  I had root caries on it, and its quite difficult to fix it. So she made a hole and had to fill it in. But after every time she tried to fill a tooth, the filling just fell out. I didn't know how stressful it was to hold your mouth open for 2 hours.. After 4 attempts the tooth was fixed and I went home..And... The filling fell out again..It's painful and I am so tired. That feeling when you have to call your dentist again......
