<s>[INST] I went to hospital 6 days ago for back tooth ache. Tooth had cap put on years ago and started to decay. I didn t know until the pain I felt sat. Penicillin doesn t seem to be working bc it s still throbbing in pain. Have an appt Monday. Dr closed today. Was going to ask for stronger antibiotic. Can I take Amox or methyl prednisone [/INST] Hi. Thanks for the query. Well it looks like there is a secondary decay due to poor fitting crown leading to Infection between the tooth and the crown. Antibiotics will reduce Infection bit is not helpful in immediate reduction of pain and for this you need to take painkillers. So better consult an Emergency room and get evaluated. They can surely give you higher antibiotics like Augmenting and along with it painkillers like Ibuprofen or Naproxen. If pain is severe Motorola or Tramadol can be advised. Hope this helps. Regards. </s>
