Hello everyone! I am in need of some advice...I went way back in June 1st to get my wisdom tooth taken out on the lower left side of my mouth. The dentist numbed my mouth using a huge needleto numb the lower left side of my mouth, after about 10 min or so she came back to check on me and it didnt kick in all the way so she used the needle in my mouth again, I wondered why she would do it again, but I guess to speed it up. But now its been four months and the half of my tongue that she numbed is still numb!! I tried biting it but nothing brings back much feeling to it. It just feels like some sort of sensition. Is this normal? I dont know what I should do this is bothering me so much thanks for reading and any advice would be much appreciated!
