I am 20 years old. Back when i was about 14 i had xrays of my mouth done and i have an extra pair of bicuspids growing. Today i looked at my gums and the bottom gums, behind the regular bicuspids, has a big bump behind each one (not sure if that's regular or not) but i looked at the bump that has been bothering me the most and there is a white tip on it. Do you think its the extra bicuspids trying to grow out??? Thanks for the help!
