How Long Does A Wisdom Tooth Extraction Take?

Most wisdom tooth extractions take between 20 and 40 minutes per tooth. A single simple extraction is often done in under 30 minutes. If the tooth is impacted or multiple teeth are removed in one visit, the procedure can take 60 to 90 minutes from start to finish. The total time you spend at the clinic will be longer because of preparation, numbing, and recovery monitoring.

What Factors Determine How Long A Wisdom Tooth Extraction Takes?

The biggest factor is whether the tooth has fully erupted through the gum. A fully visible tooth is usually quick to remove. The dentist or oral surgeon loosens it with an instrument called an elevator and then removes it with forceps. This part can take as little as 5 to 10 minutes.

Impacted teeth take longer. An impacted wisdom tooth is still partially or completely trapped under the gum and bone. The surgeon must make an incision in the gum, remove some bone, and sometimes cut the tooth into smaller pieces before removing it. This process can take 30 to 45 minutes per impacted tooth.

Other factors include the number of teeth being removed, the curvature and depth of the roots, and whether the tooth is near a nerve. Research published in the Journal of Oral and Maxillofacial Surgery found that lower wisdom teeth take longer on average than upper ones because the lower jawbone is denser. The surgeon’s experience also matters. An experienced oral surgeon typically works faster than a general dentist performing an extraction.

How Long Does The Entire Appointment Last?

If you are having all four wisdom teeth removed, expect to be at the clinic for 90 minutes to two hours. The actual surgery for all four teeth usually takes 45 minutes to an hour. The rest of the time is for check-in, signing consent forms, taking X-rays, administering anesthesia, and post-surgery recovery.

For simple single-tooth extractions, the appointment is shorter. You might be in and out in 45 minutes to an hour. For complex impacted cases involving sedation, plan for a longer visit. The American Association of Oral and Maxillofacial Surgeons notes that patients under IV sedation need to be monitored in recovery for 20 to 30 minutes after the procedure before they can go home.

You cannot drive yourself home after sedation or general anesthesia. Arrange a ride ahead of time. This is not part of the extraction time itself but is a critical part of the overall appointment.

How Long Does A Wisdom Tooth Extraction Take Under Different Types Of Anesthesia?

The type of anesthesia directly affects how long the procedure feels to you. It also affects the total appointment time because of preparation and recovery.

Local anesthesia alone is common for simple extractions. The numbing takes a few minutes to work. Once the area is numb, the surgeon proceeds. You are awake and aware of pressure but not pain. This method has the shortest total appointment time.

IV sedation adds time before the procedure because the IV is placed and medications are administered. During the procedure, you are in a deeply relaxed state and often do not remember the surgery. Afterward, you need time to wake up. General anesthesia is reserved for complex cases or anxious patients. It requires the longest preparation and recovery period.

Some people report that the procedure felt like it lasted only a few minutes under sedation, even when it took 45 minutes. The clock time is the same. The perceived time is different.

What Happens During The Extraction That Takes Up Time?

Understanding each step helps explain why a simple extraction differs from a complex one. The surgeon does not just pull the tooth. There are several distinct stages.

Numbing and sedation. If you are awake, the surgeon injects local anesthetic. This takes about 2 to 5 minutes to become fully effective. If you are under IV sedation, the anesthesiologist or surgeon administers the drugs and monitors you throughout.

Incision and bone removal. For impacted teeth, the surgeon cuts the gum tissue and folds it back. Then bone is removed with a drill or hand instrument to expose the tooth. This is often the most time-consuming step. Removing too little bone can cause the tooth to fracture during removal. Removing too much increases recovery time. The surgeon balances speed with precision.

Tooth sectioning. If the tooth is large or has curved roots, the surgeon cuts it into two or three pieces. Each piece is removed separately. This prevents excessive force on the jawbone and reduces the risk of nerve damage. Sectioning a tooth adds 5 to 15 minutes to the procedure.

Cleaning and stitching. After the tooth is out, the surgeon cleans the socket, removes any debris, and places stitches if needed. Dissolvable stitches are common. This step takes 5 to 10 minutes. The surgeon also places gauze over the socket to control bleeding.

Does The Time Differ Between Upper And Lower Wisdom Teeth?

Yes. Upper wisdom teeth are generally faster and easier to remove than lower ones. The upper jawbone is less dense. The roots of upper wisdom teeth are often straighter. The surgeon can usually remove an upper wisdom tooth in 10 to 20 minutes.

Lower wisdom teeth are more challenging. The lower jawbone is denser and thicker. The roots of lower wisdom teeth are often curved or hooked. Some roots wrap around the inferior alveolar nerve, which runs through the lower jaw. The surgeon must work carefully to avoid nerve injury. This adds time. A single lower impacted wisdom tooth can take 30 to 45 minutes.

Studies have found that lower wisdom teeth are more likely to be impacted than upper ones. The CDC reports that about 90% of people have at least one impacted wisdom tooth. Lower third molars are the most commonly impacted. If you have impacted lower wisdom teeth, your procedure will likely be on the longer side of the range.
