Ok - you guys are freaking me out here...

I just saw my biologic dentist this morning as I have a molar that has been hurting all weekend. I thought part of my filling came off and just needs to be redone - not. The dang tooth cracked right in half and now I have to have it extracted on Wednesday. I have had a headache since Sunday night.

Any advise or suggestions to prepare and afterwards? I am scared about getting a cavitation from this.

Also, when they took the x-ray to confirm the crack, they said that the tooth roots are right next to my sinus cavities and it can pose a problem - ie: be on antibiotics afterwards.

Thanks, Teri
