Allergic to most antibiotics on azithromycin possible infected tooth soonest available appointment 2 week should things be ok no pain slightly swelled?

Don't wait 2 weeks: If you have an infection you should not wait 2 weeks to see a dentist. An antibiotic alone will not cure a dental infection. You need dental treatment.

Regardless, : normally it is quite difficult for any antibiotic to get to the abscess in an abscessed tooth.The only way to cure a dental abscess is with dental treatment. The treatments are: root canal treatment, tooth extraction and/or in some cases, drainage surgery. The antibiotic is an adjunctive treatment only. Hope it helps.
