Why are teeth removed?

While many teens and some adults get their wisdom teeth removed, there are other reasons why tooth extraction may be necessary in adulthood.

Excessive tooth decay, tooth infection, and crowding can all require a tooth extraction. Those who get braces may need one or two teeth removed to provide room for their other teeth as they shift into place. Additionally, those who are undergoing chemotherapy or are about to have an organ transplant may need compromised teeth removed in order to keep their mouth healthy.

Tooth extraction is performed by a expert dentist or oral surgeon and is a relatively quick outpatient procedure with either local, general, intravenous anaesthesia, or a combination. Removing visible teeth is a simple extraction. Teeth that are broken, below the surface, or impacted require a more involved procedure.

How to prepare for a tooth extraction?

Before scheduling the procedure, your dentist will take an X-ray of your tooth. Be sure to tell your dentist about any medications you take, as well as vitamins, supplements, and over-the-counter drugs.

Tell your dentist if you will soon be treated for another medical condition with an intravenous drug called a bisphosphonate. If so, the extraction should be done before the drug treatment, or your jaw could be at risk for osteonecrosis (bone death).

Also, tell your dentist about any of the following conditions:

• a congenital heart defect
• diabetes
• liver disease
• thyroid disease
• renal disease
• hypertension
• an artificial joint
• damaged heart valves
• adrenal disease
• an impaired immune system
• a history of bacterial endocarditic

Your dentist may want to make sure all conditions are stable or treated before you undergo the tooth extraction. You might be prescribed antibiotics in the days leading up to the procedure if:

• your surgery is expected to be long
• you have an infection or a weakened immune system
• you have a specific medical condition

It’s helpful to keep the following in mind for the day of the tooth extraction in order to ensure quality treatment:

If you will be receiving intravenous (IV) anaesthesia, wear a short-sleeved shirt or loose-fitted clothing, and don’t eat or drink for six to eight hours before your appointment.

• Don’t smoke beforehand
• Tell your dentist if you have a cold, as you may need to reschedule.
• Tell your dentist if you had nausea or vomiting the night before, which may require different anaesthesia or rescheduling.
• If you’re receiving general anaesthesia, have someone with you to drive you home.

What is the procedure for a tooth extraction?

Your tooth extraction will either be simple or surgical, depending on whether your tooth is visible or impacted.

Simple extraction

You will receive a local anaesthesia, which numbs the area around your tooth so you’ll feel only pressure, not pain, during the procedure. The dentist then uses an instrument called an elevator to loosen the tooth and forceps to remove it.

Surgical extraction

You will likely receive both local anaesthesia and intravenous anaesthesia, the latter of which makes you calm and relaxed. You may also receive general anaesthesia, depending on any medical conditions. With general anaesthesia, you will remain unconscious during the procedure.

The general dentist or oral surgeon will cut into your gum with a small incision. They may need to remove bone around your tooth or cut your tooth before it can be extracted.

What are the risks of a tooth extraction?

There are a few risks for undergoing a tooth extraction; however, if your dentist recommends the procedure, the benefits likely outweigh the small chance of complications.

Usually after a tooth extraction, a blood clot naturally forms in the socket — the hole in the bone where the tooth has been extracted. However, if the blood clot does not form or dislodges, the bone inside the socket can be exposed — referred to as “dry socket.” If this happens, the dentist will protect the area by putting a sedative dressing over it for a few days. During this time, a new clot will form.

Other risks include:

• bleeding that lasts longer than 12 hours
• severe fever and chills, signaling an infection
• nausea or vomiting
• cough
• chest pain and shortness of breath
• swelling and redness at the surgical site

Contact your dentist if you experience any of these symptoms.

What is the recovery period from a tooth extraction?

It normally takes a few days to recover after a tooth extraction. The following steps help ensure that your recovery goes smoothly.

Apply an ice pack to your cheek directly after the procedure to reduce swelling. Use the ice pack for 10 minutes each time.

After the dentist places the gauze pad over the affected area, bite down to reduce bleeding and to aid in clot formation. Leave the gauze on for three to four hours, or until the pad is soaked with blood.

• Take any medications as prescribed, including over-the-counter painkillers.
• Rest and relax for the first 24 hours. Do not jump immediately into your regular routine the following day.
• Don’t use a straw for the first 24 hours.
• Don’t smoke.
• Don’t rinse for 24 hours after the tooth extraction, and spit only gently.
• Use pillows to prop your head up when you lie down.
• Brush and floss your teeth like normal, but avoid the extraction site.

The day after the procedure, eat soft foods, such as yogurt, pudding, and applesauce.
After 24 hours, add a half-teaspoon of salt to eight ounces of warm water to rinse out your mouth.
As you heal over the next few days, you can slowly reintroduce other foods into your diet.

If you are experiencing pain that isn’t going away after several days or signs of an infection —including fever, pain, and pus or drainage from the incision — make an appointment to see your dentist as soon as possible.
