I’ve had a cracked tooth for over 2 years now and it’s gotten abscesses multiple times, I always go to the emergency room and get antibiotics and then just leave it. I’ve tried getting it pulled once and I freaked out half way through the dentist pulling my tooth because of the pressure and cracking sounds so I ended up leaving. It’s recently started to bother me a lot and antibiotics are not helping much, my whole head is hurting nonstop, so I scheduled a dentist appointment to get it pulled again but I am terrified! I can’t stop shaking and it’s all I can think about. 
I was prescribed a 10mg Valium for the dentist appointment but I’m afraid it wont be enough and this tooth is going to eventually kill me.
