Key Takeaways

  • Dry socket is the most common complication after wisdom teeth removal, occurring in roughly 2% to 5% of extractions and up to 30% of impacted lower wisdom teeth. [1]
  • Signs of infection include worsening pain after the first few days, fever, pus, or a foul taste in the mouth. Contact your oral surgeon if these develop.
  • Nerve damage causing numbness or tingling in the lower lip, chin, or tongue occurs in about 1% to 5% of lower wisdom tooth extractions. Most cases resolve within weeks to months. [1]
  • Smoking, using a straw, and poor oral hygiene in the days after surgery are the most controllable risk factors for complications. [2]
  • Most complications are treatable when caught early. Know the warning signs and keep your surgeon's contact information accessible during recovery.
  • Impacted wisdom teeth and teeth close to the inferior alveolar nerve carry higher complication risks. Your oral surgeon should discuss these risks before the procedure. [1]

What This Guide Covers

This guide explains the most common problems that can happen after wisdom teeth removal and how to spot them early. It is written for patients who are preparing for extraction or are currently recovering from one.

Wisdom teeth, also called third molars, are the last teeth to come in. They typically appear between ages 17 and 25. [2] When they lack enough room to grow properly, they may become impacted, meaning they are trapped beneath the gum line or growing at an angle. Impacted wisdom teeth are more likely to need surgical removal.

Surgical extraction of wisdom teeth is one of the most common procedures in oral surgery. [1] While the vast majority of patients heal without serious problems, complications do occur. Understanding what is normal and what is not can help you get treatment sooner if you need it.

This guide covers dry socket, infection, nerve damage, bleeding, and less common complications. It also explains which risk factors you can control and when to call your oral surgeon.

Common and Uncommon Complications

The most frequent complications after wisdom teeth removal are dry socket, infection, and prolonged bleeding. Less common problems include nerve injury and jaw stiffness.

Dry Socket (Alveolar Osteitis)

Dry socket is the single most common complication following wisdom tooth extraction. It happens when the blood clot that forms in the empty tooth socket is lost or dissolves too early. Without that clot, the underlying bone and nerves are exposed to air, food, and bacteria.

Dry socket occurs in roughly 2% to 5% of all tooth extractions. For impacted lower wisdom teeth, the rate can reach up to 30%. [1] Symptoms typically begin two to four days after surgery. The hallmark sign is intense, throbbing pain that may radiate to the ear on the same side. You might also notice an unpleasant taste or bad breath.

Treatment usually involves your oral surgeon placing a medicated dressing directly into the socket. This dressing soothes the exposed bone and promotes healing. You may need to return for dressing changes every few days until the pain subsides. Over-the-counter and prescription pain medications can help manage discomfort between visits.

Several factors increase dry socket risk. Smoking is one of the strongest risk factors because the chemicals in tobacco interfere with healing and the sucking motion can dislodge the clot. [2] Using a straw, spitting forcefully, or rinsing vigorously in the first 24 hours can also displace the clot.

Infection After Extraction

Infection at the surgical site can develop in the days or weeks following wisdom tooth removal. Bacteria can enter the open wound, especially if oral hygiene is poor during recovery.

Warning signs of infection include pain that gets worse rather than better after the first two to three days, swelling that increases after the initial post-surgical swelling has peaked, fever, pus draining from the extraction site, and a persistent foul taste in the mouth. [2] If you notice any of these, contact your oral surgeon promptly.

Most post-extraction infections respond well to antibiotics. In some cases, the surgeon may need to irrigate the wound to flush out bacteria and debris. Left untreated, infection can spread to deeper tissues of the head and neck, which is rare but potentially serious. [1]

To reduce infection risk, follow your surgeon's post-operative instructions carefully. Gently rinse with warm salt water starting the day after surgery. Keep the extraction area as clean as possible without disturbing the clot. Avoid touching the wound with your fingers or tongue.

Nerve Damage and Numbness

Lower wisdom teeth sit close to two important nerves. The inferior alveolar nerve runs through the lower jaw and supplies feeling to the lower lip and chin. The lingual nerve provides sensation and taste to the tongue. Damage to either nerve during extraction can cause numbness, tingling, or altered sensation.

Nerve injury occurs in approximately 1% to 5% of lower wisdom tooth extractions. [1] The risk is higher when the tooth roots are close to or wrapped around the nerve canal. Your oral surgeon can often assess this risk with a panoramic X-ray or a cone beam CT scan (a 3D X-ray of the jaw) before the procedure.

In most cases, nerve damage is temporary. Sensation typically returns within a few weeks to several months as the nerve heals. Permanent nerve damage is uncommon but possible. [1] If you notice persistent numbness in your lower lip, chin, or tongue after surgery, report it to your surgeon so they can monitor your recovery.

Upper wisdom teeth sit near the maxillary sinus, the air-filled space above the upper back teeth. In some cases, removal of an upper wisdom tooth can create a small opening between the mouth and the sinus, called an oroantral communication. This usually heals on its own with proper care, but larger openings may need additional treatment.

Prolonged or Excessive Bleeding

Some bleeding in the first 24 hours after surgery is normal. You may notice blood-tinged saliva for a day or two. Your surgeon will have you bite down on gauze pads immediately after the procedure to help a clot form. [2]

Bleeding that soaks through gauze quickly, does not slow after 30 to 45 minutes of firm pressure, or restarts heavily after the first day may signal a problem. Contact your oral surgeon if you experience this type of bleeding. In rare cases, you may need additional treatment to stop the bleeding.

Certain medications, including blood thinners and aspirin, increase bleeding risk. Tell your oral surgeon about all medications and supplements you take before the procedure. They may coordinate with your physician about whether to adjust any medications before surgery.

Less Common Complications

While rare, other complications can occur after wisdom teeth removal. Jaw stiffness, called trismus, makes it hard to open your mouth fully. This typically resolves on its own within one to two weeks. Gentle jaw stretching exercises, as directed by your surgeon, can help.

Jaw fracture is very rare and is more likely in older patients whose jawbone is denser. Damage to neighboring teeth during extraction is also uncommon, especially when the procedure is performed by an experienced oral surgeon.

Some patients experience a temporary change in bite alignment after surgery due to swelling and muscle guarding. This usually resolves as healing progresses. If it persists beyond a few weeks, follow up with your surgeon.

Risk Factors You Can and Cannot Control

Some risk factors depend on the tooth's position and your anatomy. Others are habits you can change to improve your chances of a smooth recovery.

Factors Related to Your Anatomy and Tooth Position

The position and depth of impaction play a large role in complication risk. Fully impacted teeth, those completely trapped beneath bone, require more extensive surgery than teeth that have partially erupted. More extensive surgery means more tissue disruption and a longer recovery. [1]

Teeth whose roots are curved, hooked, or in close contact with the inferior alveolar nerve canal carry a higher risk of nerve injury. Your surgeon should review your imaging with you and explain how the tooth's anatomy affects your specific risk. Age also matters. Patients over 25 tend to have denser bone and more fully developed roots, which can make extraction more complex. [2]

Habits and Choices That Affect Recovery

Smoking is one of the strongest modifiable risk factors for dry socket and infection. The chemicals in cigarettes reduce blood flow to the gums and slow healing. The sucking motion can also pull the clot from the socket. [2] If you smoke, try to stop for at least 48 to 72 hours after surgery, and ideally longer.

Drinking through a straw creates the same kind of suction. Avoid straws for at least the first week after extraction. Vigorous rinsing, spitting, or poking the extraction site with your tongue can also disturb the clot.

Oral hygiene matters during recovery, but it requires a gentle approach. Brush your other teeth normally, but avoid the extraction area for the first day. After 24 hours, gently rinse with warm salt water several times a day, especially after eating. [2] Following your surgeon's specific post-operative instructions is the single best thing you can do to reduce complication risk.

Normal Recovery Timeline vs. Warning Signs

Knowing the difference between normal healing and a developing problem helps you decide when to call your surgeon.

What Normal Recovery Looks Like

Day 1: Expect swelling, some oozing of blood, and grogginess from anesthesia. Pain is typically manageable with prescribed or over-the-counter medications. Keep your head elevated and apply ice packs to the outside of your jaw in 20-minute intervals.

Days 2 to 3: Swelling usually peaks around 48 to 72 hours after surgery. Bruising on the cheek or jaw is common and not a cause for concern. Pain should be steady or gradually improving. Stick to soft foods like yogurt, mashed potatoes, and smoothies (no straw).

Days 4 to 7: Swelling begins to decrease. Pain should noticeably lessen each day. You can gradually reintroduce firmer foods as comfort allows. Any stitches that are not dissolvable may be removed around this time.

Weeks 2 to 4: Most patients feel largely back to normal. The soft tissue over the extraction site continues to close. Full bone healing beneath the gum takes several months, but this process happens without symptoms in most cases.

When Something Is Wrong

The key distinction is the direction of your symptoms. Normal recovery trends steadily better. A complication often shows up as a reversal, meaning pain, swelling, or bleeding that was improving suddenly gets worse.

Call your oral surgeon if you experience any of the following: pain that intensifies after day three rather than improving; a sudden spike in swelling several days after surgery; fever above 101°F (38.3°C); pus or a foul-smelling discharge from the socket; heavy bleeding that restarts after the first day; numbness in the lip, chin, or tongue that does not begin to fade within a few days; or difficulty swallowing or breathing. [1] [2]

Difficulty breathing or swallowing may indicate a serious infection spreading to deeper tissues. This is a medical emergency. Go to the nearest emergency room if this occurs.

Costs Related to Managing Complications

Treatment for complications adds cost beyond the original extraction. The exact amount depends on the type and severity of the complication.

A follow-up visit for dry socket treatment may cost $50 to $300 per visit. You may need multiple visits for dressing changes. Antibiotics for a post-surgical infection typically cost $10 to $50 with insurance, though the office visit to obtain the prescription carries its own fee. Costs vary by location, provider, and case complexity.

If nerve damage requires monitoring or referral to a specialist, additional imaging and appointments add to the total. In rare cases where complications require hospitalization, such as a deep-space infection, costs can be substantially higher.

Many dental insurance plans cover a portion of wisdom tooth extraction and related follow-up care, especially when the extraction is deemed medically necessary. Check with your insurance carrier before the procedure to understand your coverage. Ask your oral surgeon's office about payment plans if out-of-pocket costs are a concern.

When to See an Oral Surgeon vs. a General Dentist

General dentists can remove some wisdom teeth, but certain cases benefit from the additional training of an oral surgeon.

Oral and maxillofacial surgeons complete four to six years of hospital-based surgical training beyond dental school. [1] They are trained to manage complex extractions, administer deeper levels of sedation, and handle surgical complications. A referral to an oral surgeon is typical when wisdom teeth are fully impacted in bone, when roots are close to the inferior alveolar nerve, when a patient has medical conditions that increase surgical risk, or when multiple wisdom teeth need removal under sedation.

If you are already recovering and develop signs of a complication, contact the provider who performed the extraction first. They know the details of your procedure and can evaluate you quickly. If your extraction was done by a general dentist and the complication is complex, they may refer you to an oral surgeon for further management.

For routine post-operative concerns, such as mild swelling, minor oozing, or questions about your medications, a phone call to your surgeon's office is a good first step. Many offices have after-hours instructions or on-call coverage for urgent issues.

Frequently Asked Questions

How do I know if I have dry socket after wisdom teeth removal?

Dry socket typically causes intense, throbbing pain that starts two to four days after extraction. The pain often radiates to the ear. You may notice a bad taste or smell. If you look at the socket, you might see exposed bone instead of a dark blood clot. Contact your oral surgeon if you suspect dry socket so they can place a medicated dressing to relieve the pain. [1]

Is it normal to have numbness in my lip after wisdom teeth removal?

Some temporary numbness from the local anesthetic is expected and usually wears off within a few hours. Numbness that lasts beyond the day of surgery may indicate nerve irritation or injury. This occurs in about 1% to 5% of lower wisdom tooth extractions. [1] Most cases resolve within weeks to months, but let your oral surgeon know so they can track your progress.

When should I go to the emergency room after wisdom teeth removal?

Go to the emergency room if you have difficulty breathing, difficulty swallowing, or severe swelling that is spreading to your neck or eye area. These may be signs of a serious spreading infection. A fever above 101°F (38.3°C) that does not respond to medication also warrants urgent evaluation. For other concerns, call your oral surgeon's office first. [1] [2]

Can I smoke after wisdom teeth removal?

Smoking significantly increases the risk of dry socket and infection. [2] The chemicals in tobacco slow healing, and the suction from inhaling can dislodge the blood clot. Avoid smoking for at least 48 to 72 hours after surgery. Waiting a full week or longer gives the socket the best chance to heal properly.

How long does it take for wisdom teeth holes to close?

The soft tissue over the extraction site typically closes within two to four weeks. Full bone healing beneath the surface takes several months. During the first week, a blood clot protects the socket. Over the following weeks, new tissue gradually fills in the space. You can usually eat normally within one to two weeks, though some sensitivity around the area may linger. [2]

What does infection after wisdom teeth removal look like?

Signs of infection include swelling that worsens after the initial peak at two to three days, pain that increases instead of decreasing, redness or warmth around the extraction site, pus or a foul-tasting discharge, and fever. [2] If you notice any of these symptoms, contact your oral surgeon. Most infections respond well to antibiotics when treated early. [1]
