My husband has trouble with his teeth all the time, including a few abscesses. He has gone to the ER before and they did a CT scan to make sure it didn't move into his sinuses. They also gave him scripts for an antibiotic and one for pain meds. I know none of us like to go to the ER but with the holiday weekend coming up it may be the best option. Ironically I just made a dental appointment for my husband for this Saturday (a dentist that is open on Saturdays!) Good luck!
