So I had the last upper molar in the upper right quadrant removed in February and suddenly it seemed like I had a real BIG bone shard coming out...BUT today looking up at it I realized its the one remaining wisdom tooth I had which had previously been up in my sinus area but is now coming in! It's deformed a bit, awful sharp looking and I don't know at this point if I will get lucky and be able to let it replace the now missing molar. I was shocked to see this tooth coming in like this. It is sharp looking from what is exposing now, but I am wondering if it is possible that it might be usable. Do I have to have xrays to tell? What do you think?
