Most people develop wisdom teeth between ages 17 and 25, and in about 8 out of 10 people, at least one of those teeth doesn’t come in properly. What you should do depends on whether your wisdom teeth are causing problems, likely to cause problems, or sitting quietly in the right position. Healthy wisdom teeth that have fully erupted, bite correctly, and can be cleaned daily don’t need to be removed.
Signs Your Wisdom Teeth Need Attention
Wisdom teeth that are impacted (stuck below the gumline or only partially through) don’t always cause symptoms. You could have an impacted tooth for years without knowing it. But when problems develop, the signs are hard to ignore: red or swollen gums, tenderness or bleeding around the back of your mouth, jaw pain, swelling along the jawline, persistent bad breath, an unpleasant taste, or difficulty opening your mouth fully.
These symptoms often show up when the tooth becomes infected or starts pressing into neighboring teeth. A tooth that only partially breaks through the gum creates a pocket where bacteria collect easily, since the back of your mouth is already difficult to clean. That pocket can lead to repeated gum infections, a condition called pericoronitis, which tends to flare up over and over until the tooth is dealt with.
When Removal Is Necessary
The American Dental Association lists several clear reasons for extraction: pain in or near the wisdom teeth, repeated soft tissue infection behind the last molar, cysts (fluid-filled sacs that can damage bone and nearby tooth roots), tumors, damage to adjacent teeth, gum disease, or extensive decay. Wisdom teeth that grow in only partway are especially prone to cavities that can’t be repaired with fillings, leaving removal as the only option.
Some dentists recommend removing wisdom teeth before they cause symptoms, particularly in younger patients whose jawbone is less dense and whose tooth roots haven’t fully formed. Recovery tends to be faster and complications fewer when the surgery happens earlier. Others prefer a watch-and-wait approach, monitoring the teeth with regular X-rays and stepping in only if trouble develops. Both strategies are reasonable, and the right call depends on the position of your teeth and your individual risk factors.
Types of Impaction
How a wisdom tooth is positioned under the gum affects both the likelihood of problems and the complexity of removal. There are four main patterns:
- Mesial (angled forward): The most common type. The tooth tilts toward the front of your mouth and can press into the neighboring molar. Dentists often monitor these before deciding on extraction.
- Vertical: The tooth points in the right direction but stays trapped below the gum. Many vertical impactions don’t cause issues and may not need removal unless they press against bone or displace a neighboring tooth.
- Horizontal: The tooth lies completely sideways, pushing directly into the adjacent molar. This type almost always requires surgical extraction and sometimes involves removing a small amount of jawbone to get the tooth out.
- Distal (angled backward): The tooth tilts toward the back of the mouth. Relatively rare. Whether it needs removal depends on the angle and how much pressure it places on surrounding structures.
What the Procedure Is Like
Wisdom tooth removal ranges from straightforward to surgical depending on whether the tooth has erupted or is stuck beneath bone. There are three anesthesia options. Local anesthesia numbs the area around the tooth while you stay fully awake. IV sedation delivers medication through a line in your arm that makes you feel sleepy and relaxed; you won’t feel pain and likely won’t remember much, but you breathe on your own throughout. General anesthesia puts you fully to sleep and is reserved for more complex cases.
Most wisdom tooth removals use IV sedation. The procedure itself typically takes 30 to 60 minutes for all four teeth. For a simple extraction of a fully erupted tooth, the cost ranges from about $120 to $250 per tooth. Surgical extraction of an impacted tooth runs higher, roughly $180 to $800 per tooth, depending on complexity and the type of anesthesia used.
Recovery: What to Expect Week by Week
Full recovery takes up to two weeks, but the worst of it is concentrated in the first few days. For the first 24 hours, stick to liquids: broth, smooth soups, smoothies (no straw), yogurt, pudding, and milkshakes. Avoid hot drinks, and don’t rinse or spit, since the suction and heat can dislodge the blood clots forming in your sockets. Those clots are essential. They protect the exposed bone and nerves underneath while the tissue heals.
After the first 24 hours, you can move to soft foods: mashed potatoes, scrambled eggs, oatmeal, pasta, bananas, avocado, applesauce, and soft bread. Gentle mouth rinsing (especially after meals) is fine at this point and helps reduce gum soreness. By day four or five, you can start reintroducing more normal foods, though you should still avoid anything hard, crunchy, or chewy. Bruising around the jaw can linger for up to two weeks.
Skip strenuous exercise for the first few days. You can usually brush your teeth normally within a few days of surgery, being careful around the extraction sites.
Avoiding Dry Socket
Dry socket is the most common complication after wisdom tooth removal, occurring in about 4% of lower jaw extractions. It happens when the blood clot in the socket dissolves or gets knocked loose too early, leaving bone and nerves exposed. The pain is significant and typically shows up three to five days after surgery. People who had a gum infection before surgery face a higher risk (around 6%), and smokers are more than three times as likely to develop it.
To protect the clot:
- Don’t smoke or use any tobacco or nicotine products (including vapes and chewing tobacco) during recovery.
- Avoid straws for at least a week. The suction can pull the clot right out.
- Skip carbonated and hot drinks in the early days.
- Don’t rinse vigorously. Gentle swishing only, and not until 24 hours after surgery.
- Avoid hard, crunchy, or chewy foods like chips, popcorn, nuts, seeds, and jerky.
Other Possible Complications
A large retrospective study of nearly 1,200 lower wisdom tooth removals found an overall complication rate of 8.4%. Beyond dry socket, the most common issues were abscess (1.25%), temporary numbness or tingling in the lip or tongue (1%), wound separation (0.6%), persistent sensation changes (0.5%), and post-operative bleeding (0.4%). The risk of nerve-related numbness was significantly higher when X-rays showed the tooth roots sitting close to the nerve canal in the lower jaw.
Most of these complications resolve on their own or with minor treatment. Persistent nerve sensation changes (lasting beyond a few months) affected only 1 in 200 patients in that study. Your oral surgeon can assess your specific risk based on the position of your teeth relative to the nerve before the procedure.
Foods and Drinks to Avoid
During the first week of recovery, steer clear of popcorn, chips, crackers, nuts, seeds, rice, quinoa, spicy foods, acidic drinks (orange juice, lemonade), alcohol, high-sugar foods, and anything chewy like taffy or jerky. Small grains and seeds are especially problematic because they can lodge in the open sockets and trigger infection. Acidic and spicy foods irritate raw tissue. Alcohol can interfere with healing and interact with pain medication.
