Wisdom teeth removal is a routine oral surgery where a dentist or oral surgeon extracts one or more of your third molars, the last teeth to come in at the back of your mouth. The procedure typically takes 45 minutes or less and involves numbing or sedating you, opening the gum tissue if needed, removing any bone blocking the tooth, and pulling or sectioning the tooth out. Most people return to normal activities within two to three days.
Why Wisdom Teeth Need to Come Out
Wisdom teeth that grow in fully, stay healthy, and have enough room in your jaw don’t need to be removed. But that’s not the typical scenario. Most people’s jaws don’t have space for these extra molars, which usually try to emerge between ages 17 and 25. When they can’t come in properly, they become impacted, meaning they’re stuck partially or fully beneath the gum line.
The American Association of Oral and Maxillofacial Surgeons recommends extraction when a wisdom tooth causes dental pain, infection, gum disease, cavities, cysts, or damage to neighboring teeth. Poor oral hygiene around a partially erupted wisdom tooth is another common reason, since those hard-to-reach areas trap bacteria easily. Even wisdom teeth that aren’t causing symptoms right now are sometimes removed preventively if imaging shows they’re positioned to cause problems later.
Types of Impaction
How your wisdom tooth is angled beneath the gum determines how complex the extraction will be. There are four main types:
- Mesial impaction: The most common type, where the tooth is angled forward toward the front of your mouth, pressing into the molar ahead of it.
- Vertical impaction: The tooth is nearly upright in a normal orientation but can’t fully break through the gum.
- Horizontal impaction: The tooth is lying completely on its side, often requiring more involved surgery.
- Distal impaction: The tooth is angled toward the back of your mouth, away from the other teeth.
Your surgeon will take X-rays or a 3D scan beforehand to see exactly how the teeth are positioned, how deep they sit, and how close their roots are to the nerve that runs through your lower jaw.
Preparing for the Procedure
What you need to do before surgery depends on the type of sedation you’ll receive. If you’re getting sedation through an IV, you typically can’t eat or drink for eight hours beforehand. For morning surgeries, that means nothing after midnight, though clear liquids (water, apple juice, anything you can see through) are usually allowed up to four hours before. If you’re only getting nitrous oxide (laughing gas), the fasting window is shorter, usually about three hours.
You should stop smoking at least 12 hours before surgery, and ideally cut back in the days leading up to it. Smoking slows healing and increases the risk of complications afterward. If you’re receiving any form of sedation, a responsible adult needs to come with you, stay at the office during the procedure, and drive you home.
Anesthesia Options
You won’t feel pain during the extraction regardless of which option you and your surgeon choose. There are three levels:
With local anesthesia alone, you get numbing injections near the extraction site. Your surgeon will typically apply a topical gel to your gums first so the needle itself is less uncomfortable. You stay fully awake and aware but feel only pressure, not pain. This is common for straightforward extractions.
IV sedation is the most popular choice for wisdom teeth. Medicine delivered through a line in your arm makes you feel deeply relaxed and sleepy. You won’t feel pain, and most people remember little to nothing about the procedure afterward. Your gums are also numbed with local anesthesia once you’re sedated. You breathe on your own throughout.
General anesthesia is reserved for more complex cases. You breathe in medicine through a mask or receive it through an IV, and you fall completely asleep. Unlike IV sedation, general anesthesia requires a ventilator to breathe for you. Most wisdom tooth removals don’t need this level of sedation.
What Happens During the Surgery
Once the anesthesia takes effect, the surgeon makes an incision in the gum tissue to expose the tooth and the bone around it. If bone is covering or blocking part of the tooth, the surgeon removes that bone to access the root.
Teeth that are large or deeply impacted are often sectioned, meaning the surgeon divides the tooth into smaller pieces rather than pulling it out whole. This requires less bone removal and makes the extraction easier on surrounding tissue. Each piece is lifted out individually.
After the tooth is out, the surgeon cleans the socket of any debris or bone fragments, then closes the gum with dissolvable stitches if needed. Gauze is placed over the extraction site, and you bite down on it to help a blood clot form. The entire process for all four wisdom teeth typically takes under an hour.
Recovery: What to Expect Each Day
The first 24 hours are the most critical. Blood clots form in the empty sockets, and protecting those clots is the single most important thing you can do for your recovery. Don’t use straws, spit forcefully, or rinse your mouth vigorously during this window. After 24 hours, you can begin gently rinsing with an antiseptic or saltwater rinse.
Swelling and discomfort peak around days two and three, then start to improve. Many people feel well enough to return to work or school by day two or three. Stick to soft foods during this time: lukewarm or cool soups blended until smooth, yogurt, applesauce, ice cream, mashed potatoes. Avoid hot foods and drinks, which can irritate the wound. The goal is to eat foods that won’t leave chunks behind in the extraction sites and that provide enough calories and nutrients to support healing.
By days seven to ten, jaw stiffness and soreness should fade significantly. Dissolvable stitches break down on their own during this window, or your surgeon will remove non-dissolvable ones at a follow-up appointment around the one-week mark. Full healing of the bone and soft tissue beneath the surface continues for several weeks, but you’ll feel mostly normal well before that.
Dry Socket
Dry socket is the most common complication, affecting about 2% to 5% of all tooth extractions. It happens when the blood clot in the socket dislodges or dissolves too early, exposing the underlying bone and nerves. The result is intense, throbbing pain that typically starts two to four days after surgery, often radiating to your ear, and a noticeable bad taste or odor in your mouth. Smoking, using straws, and vigorous rinsing in the first few days all increase the risk. If you develop dry socket, your surgeon can place a medicated dressing in the socket to relieve pain and promote healing.
Nerve Injury Risk
The lower jaw contains a nerve that provides sensation to your lower lip, chin, and tongue. Because lower wisdom teeth roots can sit very close to this nerve, there’s a small risk of nerve injury during extraction. In a study of patients whose teeth were confirmed to be near the nerve on imaging, about 17% experienced some numbness or altered sensation one month after surgery. That number represents a higher-risk group, not all extractions.
Most nerve injuries follow a predictable pattern: some resolve within the first three months, while others can take up to a year. A small number become permanent. Two factors increase the risk significantly. Deeper impaction raises the odds substantially, and each additional year of age increases the risk by about 6%, which is one reason surgeons often recommend removing wisdom teeth in your late teens or early twenties rather than waiting.
