What are the symptoms of a tooth abscess? Will it go away on its own, or do I have to go to the dentist?

Answer

A tooth abscess is a collection of pus that forms due to a bacterial infection in the roots of teeth or in the gum tissue surrounding teeth. The main symptom of a tooth abscess is a severe, persistent, throbbing toothache. Initially, the tooth may be sensitive to heat and pressure with chewing or biting. Later, you may develop a fever, swelling in your face or cheek, and tender, swollen lymph nodes under your jaw or in your neck. If the abscess ruptures, you will have a sudden rush of foul-smelling and foul-tasting fluid in your mouth.

A tooth abscess will not go away without treatment. If the abscess ruptures, the pain may decrease significantly, but dental treatment is still needed. If the abscess doesn't drain, the infection can spread to other areas of the head and neck and even become life-threatening.

Treatment of a tooth abscess is directed at eliminating the infection, preserving the tooth and preventing complications. Treatment may include:

• Draining the abscess
• Antibiotics
• Warm saltwater rinses
• Over-the-counter pain relievers
• Root canal therapy
• Extraction of the affected tooth
