I was sick and using cough drops for a few days, I noticed that i was keeping the cough drop behing my two front teeth mostly and it started to swell, now i have quit using cough drops but the swelling has spread around behing all four of my front teeth. It is really painful and I am starting to get worried, do I need to go to a dentist? I do not have insurance or ehough money for a hefty bill, so Going will be a last resort.
