What to if i am having all 32 of my teeth extracted, i need to know what to expect?

Depends on condition: Are they all loose and periodontally involved? Any impacted teeth? Any infections? Your best bet is to ask the surgeon removing your teeth... Without being able to examine you, it is hard to give you proper advice. All the best...

Proper Preparation: That's an extensive amount of teeth to be taken out at one visit. All your questions should be answered so that you understand what is going to be done, why, and what to expect by your treating dentist (both oral surgeon and general dentist\prosthodontist). They are the ones who know you, your medical and dental history and your specific circumstances best.
