Short answer
A tooth extraction removes a tooth that cannot be saved or that is causing problems, such as a wisdom tooth. The area is numbed first. Afterwards, a blood clot forms in the space, and protecting that clot is the key to healing well.
Why is a tooth removed?
- Severe decay or damage that cannot be repaired.
- Advanced gum disease.
- Infection.
- Crowding, or preparing for orthodontic treatment.
- A wisdom tooth that is impacted, painful or causing problems.
Simple and surgical extraction
A simple extraction removes a tooth that can be seen in the mouth. A surgical extraction is used when a tooth is broken at the gum line or has not fully come through, as can happen with wisdom teeth. Your dentist will explain which kind you need.
The procedure
- Exam and X-rays.
- Numbing. Sedation may be available if you feel anxious. See our sedation guide.
- Removal of the tooth.
- Gauze is placed to control bleeding, and you receive aftercare instructions.
Aftercare and healing
- Bite gently on the gauze as directed to control bleeding.
- For the first day, do not rinse hard, spit, smoke or use a straw. These can dislodge the clot.
- Eat soft foods and avoid chewing on the area.
- Use cold packs for swelling and over-the-counter pain relief as directed.
- Keep brushing the rest of your mouth, avoiding the site at first.
- Call the clinic if pain gets worse after a few days, if bleeding will not stop, or if you have fever or swelling that grows.
A painful empty socket, called dry socket, can happen if the clot is lost. It needs a dentist's care.
Wisdom teeth in older adults
Some people keep wisdom teeth for years without trouble. Older adults may be told these teeth need to be removed because of decay, gum disease or infection. Healing can take longer with age, and your health and medications matter. Your dentist will explain the risks and benefits for you.
