A dental abscess
is a collection of pus in or around a tooth. A dental abscess is caused by bacteria. The bacteria usually enter the tooth when the enamel (outer part of the tooth) is damaged by tooth decay. Bacteria may also enter the tooth through a break or chip in the tooth, or a cut in the gum. Food particles that are stuck between the teeth for a long time may also lead to an abscess.
Signs and symptoms of a dental abscess:
- Toothache, a loose tooth, or a tooth that is very sensitive to pressure or temperature
- Bad breath, unpleasant taste, and drooling
- Pain, redness, and swelling of the gums, or swelling of your face and neck
- Pain when you open or close your mouth
- Trouble opening your mouth
Seek care immediately if:
- You have severe pain.
- You have trouble breathing because of pain or swelling.
Contact your healthcare provider if:
- Your symptoms get worse, even after treatment.
- Your mouth is bleeding.
- You cannot eat or drink because of pain or swelling.
- Your abscess returns.
- You have an injury that causes a crack in your tooth.
- You have questions or concerns about your condition or care.
You may need any of the following:
- Medicines may be given to treat a bacterial infection and decrease pain.
- Incision and drainage is a cut in the abscess to allow the pus to drain. A sample of fluid may be collected from your abscess. The fluid is sent to a lab and tested for bacteria. Ask your healthcare provider for more information.
- A root canal is a procedure to remove the bacteria and prevent more infection. It is usually done after an incision and drainage. A filling or crown will be placed over the tooth after you have healed from your root canal.
- Tooth removal may be needed if the infection affects deeper tissues. This is usually done after an incision and drainage.
- Rinse your mouth every 2 hours with salt water. This will help keep the area clean.
- Gently brush your teeth twice a day with a soft tooth brush. This will help keep the area clean.
- Eat soft foods as directed. Soft foods may cause less pain. Examples include applesauce, yogurt, and cooked pasta. Ask your healthcare provider how long to follow this instruction.
- Apply a warm compress to your tooth or gum. Use a cotton ball or gauze soaked in warm water. Remove the compress in 10 minutes or when it becomes cool. Repeat 3 times a day.
Prevent another abscess:
- Brush your teeth at least 2 times a day with fluoride toothpaste.
- Use dental floss to clean between your teeth at least once a day.
- Rinse your mouth with water or mouthwash after meals and snacks.
- Chew sugarless gum after meals and snacks.
- Limit foods that are sticky and high in sugar such as raisons. Also limit drinks high in sugar, such as soda.
- See your dentist every 6 months for dental cleanings and oral exams.
