I went to an emergency dentist and have been given antibiotics. I've been taking them for 4 days and the pain is still so bad I can't eat or sleep. I thought the antibiotics would be helping by now. I'll contact my dentist tomorrow when they open and hopefully they'll be able to see me ASAP. I've also googled that tooth infections and spread to the brain so freaking out about that a bit. Anyone had this happen? Will the antibiotics work? I can't cope with the pain much longer.
