Antibiotics. The antibiotic may calm down the abscess for a short time, but it takes 48 hours for antibiotics to work. Depending upon the size of the access, antibiotics may not be effective until after the access is drained, tooth removed, or pulp tissue removed. Don't rely on antibiotics to "buy you time" a tooth abscess is serious. Missing a day of work now, may keep you from missing a week or two later.
None. If you have an abscess do not wait please see your nearest dentist asap. If turns to spread of abscess can be more serious.
