Went to the OS for a consult today. Upper wisdom teeth are in and bottom wisdom teeth are impacted. Went for consult because #18 molar has an abscess with bone loss and regular dentist thought that there was infection around the wisdom tooth also. After OS did another set of xrays, he said no infection or cyst around wisdom tooth so it does not need to come out (thank goodness). His advice was to pull #18 molar, clean out infection, and do bone graft using cow bone ? or synthetic material. Am I understanding right, he pulls the tooth, cleans out the area and packs in this synthetic material and sews it together so there is no worry about dry socket? Also, what is the synthetic bone material made of and is it safe to have in your gums? He also suggested that since he saw a small cavity between an upper tooth and the wisdom tooth that I should probably pull both upper wisdom teeth also. Why would I do that if they've grown in straight and have no infection around them? That doesn't make sense to me. Also I don't want to be put out for the molar extraction and bone graft...is that a bad decision? Thanks for all your help and your knowledge.
