No need to be scared, I had my wisdom tooth removed 5 years ago , never had any problems but my wisdom tooth kept bugging me with dull pain, an xray showed it pushed on my last molar's root and therefore kinda pressuring it causing the pain, naturally it had to be corrected so the dentist had to do not just a plain extraction but correct the position of my wisdom tooth and completely take out my last molar ( which put a very good struggle ). The dental assistant had to hold my head back coz the dentist said my tooth had a very good grip to the base even in one root. I didnt feel a thing while they were doing all of this , and actually was quite amused thinking how strong my tooth is Well it is kinda funny looking at the face of the dentist strugglingto puul my tooth out with my head following and had to be held firmly back, took them about 5 sweaty minutes just to pull it out ( again totally painless) after which they had to take drink hehehehe Sometimes it doesnt pay to have strong teeth
