I have dental phobia haven't been dentist for years lower broken tooth tender and small swelling in face i think it's an abscess will antibiotics help?

Briefly: Antibiotics will help for a period of time, but do not cure the infection. It will return and the antibiotics may not work a second time. Because of your prescribed steroids you may not be able to fight off the infection well. See a dentist as soon as possible, let them know of your fears and speak to the staff so that they can help you. Your fear is not unusual and can be managed.

See a dentist ASAP: A tooth infection won't go away without treatment and the infection may spread to your jaw, cheeks, sinus and to other areas of your body. Dentist will treat a tooth abscess by treating the cause and getting rid of the infection. With the profound local anesthesia and IV sedation you will have no recall of the events of the treatment or experience any pain. Good luck.

Phone call: The best way to treat this problem is to call a dentist. There are no diy remedies for fixing broken down teeth. The sooner you call the sooner you will feel better. You have been suffering needlessly. Antibiotics may minimize the symptom but they will not solve your problem.
