yes alot of people have extra teeth ... i had 8 extra teeth and they had to be removed b4 i got my braces on as well.... its called supernumerary teeth....its actually very common....
yea oral surgery will be them prolly putting you to sleep for an hour and cutting the impacted tooth out.... dont worry you will be sleeping and wont feel anything... just make sure you take care of it after to prevent infection.....
you get teeth until the age 21... you might have started getting your wisdon or 3rd molars cause they start coming in from 17--21
I just found out at age 54 that I too, have an extra tooth on the bottom front. I have some bite issues, but dentist told me "it seems to be working for you", so not all extra teeth have to be pulled.
Hang in there. You are young and it will be OK
I don't think this is normal, but I've heard stories of extra teeth so I guess it happens occasionally. And yes, they will have to cut your gum to remove the extra teeth. Good Luck.
