hello and welcome to hcm forum,
i am glad you wrote in , according to the dental history provided by you it seems you have been taking antibiotics for quite a while now, and due to prolonged use of antibiotics resistance develops,therefore i would advise you to visit an oral surgeon,
swelling in the jaw may be due to an
abscess which is now widespread, causing difficulty in chewing, therefore it is very important for you to see a
dentist, antibiotics alone won't help, abscess needs to be drained out.
i advise you to start using an antibacterial(
betadine) mouth wash,twice/day ,until you see your dentist,
i hope answered your query,
i wish you good health,
take care.
