I have been taking antibiotics for 48 hrs. for an abcess tooth. and my face is still very swollen. how long till it goes down.

It depends: The swelling is going to depend on the infection and on your medical condition, you should ask your doctor this question because he knows your diagnosis and the kind of antibiotics you're on. Good luck and hope you feel better very soon.

Depends: Antibiotics take time to work and it is important to take the full course prescribed for you. An abscess is a pocket of infected material, in the dental context, usually related to a dying tooth and presents at the apex of the root. Pus, the main fluid in an abscess reduces the effectiveness of the antibiotic locally, so it takes a bit of time to work.

See oral surgeon now: Don't wait for it "to go down"". This infection can spread to vital areas of your face and neck. A surgical procedure, incise and drain, as well as a change in antibiotic therapy may be necessary. Also to eliminate the source of the infection the tooth may require extraction or root canal therapy once the swelling is reduced.

RCT might be needed : You might need rndodontic treatment of the tooth. Antibiotics might not be the answer. Sweeping might stay until treatment is done.

See your dentist: They need to treat the cause of the swelling. Antibiotics may slightly reduce the symptoms but the cause needs to be determined and properly addressed. They need to decide if you need root canal treatment, periodontal gum line treatment or tooth extraction.

48 hrs: Your swelling can take several day to go away completely. If it is not getting any smaller you may need another antibiotic or treatment.

3 day peak: Antibiotics usually take 3 days to "kick in" if by third day you are not improving or getting substantially worse call your dentist, see and oral surgeon or go t to er asap.
