A dental abscess is a collection of pus in or around a tooth. A dental abscess is caused by bacteria. The bacteria can enter the tooth when the enamel (outer part of the tooth) is damaged by tooth decay. Bacteria can also enter the tooth through a 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.

DISCHARGE INSTRUCTIONS:

Return to the emergency department if:

• You have severe pain in your tooth or jaw.
• You have trouble breathing because of pain or swelling.

Call your doctor 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.

Medicines:

You may need any of the following:

• Antibiotics help treat a bacterial infection.
• NSAIDs , such as ibuprofen, help decrease swelling, pain, and fever. This medicine is available with or without a doctor's order. NSAIDs can cause stomach bleeding or kidney problems in certain people. If you take blood thinner medicine, always ask your healthcare provider if NSAIDs are safe for you. Always read the medicine label and follow directions.
• Acetaminophen decreases pain and fever. It is available without a doctor's order. Ask how much to take and how often to take it. Follow directions. Read the labels of all other medicines you are using to see if they also contain acetaminophen, or ask your doctor or pharmacist. Acetaminophen can cause liver damage if not taken correctly.
• Prescription pain medicine may be given. Ask your healthcare provider how to take this medicine safely. Some prescription pain medicines contain acetaminophen. Do not take other medicines that contain acetaminophen without talking to your healthcare provider. Too much acetaminophen may cause liver damage. Prescription pain medicine may cause constipation. Ask your healthcare provider how to prevent or treat constipation.
• Take your medicine as directed. Contact your healthcare provider if you think your medicine is not helping or if you have side effects. Tell your provider if you are allergic to any medicine. Keep a list of the medicines, vitamins, and herbs you take. Include the amounts, and when and why you take them. Bring the list or the pill bottles to follow-up visits. Carry your medicine list with you in case of an emergency.
