Hello, so I went to the emergency dentist on Saturday morning because a tooth I have a crown on was hurting so much I hadn’t been able to sleep the night before. The dentist told gave me Amoxicillin for the infection and Ibuprofen, apparently my gums were getting deeper due to bruxism so it had become bad and I need to get a mouth guard soon. Well, the pain was excruciating even though I don’t have a root there (I got a root canal there years ago) until yesterday afternoon since nothing calmed it, not ibuprofen, not paracetamol, not anything. I tried a benzocaine spray for the affected area yesterday at around 3 p.m. and the pain subsided quite a lot and I could actually get up from bed. The thing is, since 7 p.m. yesterday the affected areas started selling and during the night it did some more, the area now feels tight when I move it and the touch is soft but painful. I’m worried because I’ve been taking amoxicillin for the infection but the swelling began only yesterday night. Maybe it could be an allergic reaction or something is not working. I am thinking of going to the regular ER since the emergency dentist is too far away and I don’t have anyone to take me today. Should I go or is this normal? I’m worried.
