I've had a stubborn infection in a root-filled tooth for the last month, had amoxicillin twice and metronidazole once. Finished a week of Amoxy on Friday and by Saturday night the pain was back. This time it seems different though, it feels like the pain is in my jaw bone/cheek bone and I feel like there's swelling in my face/jaw. It's not as painful as it has been previously, so had made an appt to go back to the dentist at the end of this week before the swelling started. Now I'm wondering if I need to see if I can get in earlier? I'm on the waiting list for an extraction so I don't think there's a huge amount he can do before then, and he said last time he'd be reluctant to keep prescribing antibiotics but it seems like that's all that's keeping it at bay.
