I counted again and think it's not a wisdom tooth. It's the 7th (last) tooth from the centre of my mouth. I think wisdom teeth are the 8th and i don't have any of those which is odd because i read online that they are supposed to come in by age 25 at the lastest.
Anyway, I don't know if that changes anything with it not being a wisdom tooth. Probably not, still scared to go back. My family think I should change dentists and get a second opinion.
Now I'm nervous because I have to go find another dentist and ask them if my dentist was right.
