Hello. Im a 20 year old girl. I recently got dental braces and had to extract 5 of my teeth. (From center teeth on both sides its teeth number 4, top and bottom and a wisdom tooth number 28) I already took out 3, but the fourth tooth my dentist said she would refer me to a specialist to remove the wisdom tooth, the other 4th tooth and a CYST.I know a little bit on what a cyst is (liquid or air or fluid filled sac).I want to know how would they treat the cyst if it is above my 3 teeth. The cyst appeared on my exray when i had to extract my teeth. Is a serious problem? Is it a type of cancer? what are the possible reasons for this cyst?Some years ago i fell of my bicycle and injured myself just under my nose (almost where the cyst is). I had a scar under my nose, but since i didnt notice it, it has almost completly disappeared. Could that injury be the cause of the cyst?Please help. I m afraid of finding out that it is a serious problem a little too late.Thank You.Tiyane
