In addition to examining your tooth and the surrounding area, your dentist may:
- Tap on your teeth. A tooth that has an abscess at its root is generally sensitive to touch or pressure.
- Recommend an X-ray. An X-ray of the aching tooth can help identify an abscess. Your dentist may also use X-rays to determine whether the infection has spread, causing abscesses in other areas.
- Recommend a CT scan. If the abscess has spread to other areas within the neck, a CT scan may be used to assess the extent of the infection.
The goal of treatment is to get rid of the infection. To accomplish this, your dentist may:
- Open up (incise) and drain the abscess. The dentist will make a small cut into the abscess, allowing the pus to drain out, and then wash the area with salt water (saline).
- Perform a root canal. This can help eliminate the infection and save your tooth. To do this, your dentist drills down into your tooth, removes the diseased central tissue (pulp) and drains the abscess. He or she then fills and seals the tooth's pulp chamber and root canals. The tooth may be capped with a crown to make it stronger, especially for a molar tooth. If you care for your restored tooth properly, it can last a lifetime.
- Pull the affected tooth. If the affected tooth can't be saved, your dentist will pull (extract) the tooth and drain the abscess to get rid of the infection.
- Prescribe antibiotics. If the infection is limited to the abscessed area, you may not need antibiotics. But if the infection has spread to nearby teeth, your jaw or other areas, your dentist will likely prescribe antibiotics to stop it from spreading further. He or she may also recommend antibiotics if you have a weakened immune system.
Lifestyle and home remedies
While the area is healing, your dentist may recommend these steps to help ease discomfort:
- Rinse your mouth with warm salt water.
- Take over-the-counter pain relievers, such as acetaminophen (Tylenol, others) and ibuprofen (Advil, Motrin IB, others), as needed.
Preparing for your appointment
You're likely to start by seeing your dentist.
What you can do
Here's some information to help you get ready for your appointment:
