Hi im a 15yo and have noticed a medium sized bump above my right Canine tooth with a white top, the top is flat unlike a pimple, and not as severe as a festula. It doesnt hurt unless I poke at it. It wont pop and nothing is draining out of it (that i know of. no funny tastes from that area or smells). I was reading another case where someone had somthing similar, but a bit more extreme, and needed surgery. Ive tried gargling salt water at first, which didnt irritate it even after I had been poking at it, but now its not working and Im getting concerned.

Please help. I realy hope its nothing and will pass but Im not 100% sure.
