I need a root canal and my dentist prescribed amoxicillin for me recently. After that ran out, I accidentally bumped my jaw and aggravated the infection and overnight it swelled my entire right cheek/jaw. She now has prescribed clindamycin 300mg for me. I've read that this is all that will be necessary to eliminate the swell but I'm wondering where all of that fluid will go? I'm sure it doesn't just "vanish". There's no visible abscess inside my mouth at all, nor outside. Will it eventually need incision? I'm just wondering if she's trying to get more money out of me or actually suggesting the necessary steps before root canal...
