Re: White pimple like bump on roof of mouth
you almost certainly have an abcessed tooth. it has been probably been going on a long time (that is, the tooth pulp/nreve died a long time ago). sometimes there won't be pain for days, months, maybe even years. then wham! the infection in the pulp gets out of control and the pus tried to tunnel out of the tooth. the path of least resistance is often through the bone and the result is the little white dot(s) you disturbed. your dentist will test to see which tooth it is, then you can decide it you want it repaired (root canal) or extracted. i'm surprised you're not i more pain than you are given the level of swelling, but that is the unpredictable nature of chronic dental infections. you may wind up with 10 days of antibiotic too, just to be on the safe side, if the tooth can't be easily drained and you decide you want to keep it. hope this helps.
