Antibiotics: Antibiotics do not cure infected teeth, only limit the spread of infection. Pills alone won't do it. Sounds like you have abscessed (infected) tooth/teeth and infection is spreading. Now that you're off the antibiotic infection will come roaring back. You must see a dentist for definitive treatment. Don't self medicate. Get to dentist immediately.

Evaluation: This needs to be evaluated by someone who can treat you. Please call for an appointment/.

See dentist: An antibiotic may make you feel better in the short term but it will not cure the problem. See a dentist for an evaluation ns proper treatment of this lump.

Oral surgeon: I would recommend seeing an oral surgeon. Sometimes it is an outgrowth of the bone (tori) and is not a serious problem unless dentures are required. But hard to say. I would see an oral surgeon, get an x-ray and be evaluated.
