Hi BJ,
Anytime there is swelling in the jaw, it is imperative to see a dentist asap. It could be an abcessed tooth or an infected gland. Massive or rapid swelling in the lower jaw near the molars can be what is called Ludwig's angina. This is a bacterial infection of the floor of the mouth that occurs from an infected tooth or a mouth injury. It is very serious and can actually block the airway. It is not something that will go away on it's own and needs medical/dental attention asap.

Even people with perfect teeth get oral infections. Teeth that have fillings in them are more prone to infection due to microscopic cracks in the fillings of which bacteria get into and multiply.

I'm 30 years in dentistry and see alot of swollen faces ........ do not wait to seek medical/dental attention. Call your dentist and leave an urgent message on his machine or go the the ER at your local hospital and see their dentist on staff.

I hope your problem is not too serious and easily remedied. Please let us know how you are doing.
