i have a lot of pain, swelling on my lower back molar. a month ago i had the same thing and it went away with brushing/flossing but it formed a flap near the back molar. i called the dentist on saturday and he wrote me a script for amoxicillan and is going to get me in on monday or tuesday. said i most likely have a wisdom tooth infection. i am 27 and havent had them removed because they never affected me. anyone else have anything like this?
