Been on amoxicillin for 84 hrs. had an antibiotic shot after 48 since no change. still no change. what to do? it's for abscess tooth.

Infection: It can take up to 48 hours for an antibiotic to take effect so it appears that this antibiotic is not effective on this particular infection. Call the dentist that perscribed the antibiotic and it may need to be changed. If there is swelling that makes it hard to swallow or breath go the er.

Antibiotics: Antibiotics don't cure infected teeth, only reduce spread of infection into surrounding tissues. To cure the infection you must have root canal/crown or extraction/implant/crown. As antibiotic not working you need dental treatment sooner rather than later.

See dentist: it could be the antibiotics given are not correct for the bacteria involved. And sometimes you must get treatment before the swelling subsides,no matter what antibiotic your given. See your dentist ASAP!

See a dentist: A tooth abscess won't go away without treatment and the infection may spread to your jaw, cheeks, sinus and to other areas of your head and neck. A dental abscess is a collection of pus that forms in your teeth or gums as a result of a bacterial infection. Dentist will treat a tooth abscess by treating the cause and getting rid of the infection. See your dentist ASAP.

Dentist please: I may be mistaken, but your question suggest that you did not get your antibiotics from the dentist, either at the ER or a clinic ? You should actually see a dentist to treat the abscess, antibiotics alone can not eliminate the reason of the abscess witch is the tooth, so, please seek treatment from a dentist ASAP. If not treated the abscess may spread to other teeth and may loose them. Take care.
