Wisdom teeth removal is a multi-step process that starts well before the surgery itself and continues through roughly two weeks of healing. The procedure typically takes 45 minutes to an hour for all four teeth, though the complexity depends on whether the teeth have fully erupted or are trapped beneath bone. Here’s what happens at each stage.
Imaging and Pre-Surgical Planning
Before anything else, your dentist or oral surgeon needs to see exactly where your wisdom teeth sit and how they relate to surrounding structures. A panoramic X-ray is the standard tool for this. It captures your entire jaw in a single image, showing the position, angle, and development of all four third molars at once. The FDA recommends this imaging in late adolescence, between ages 16 and 19, when the roots are still forming and the teeth are easier to remove.
What the surgeon is looking for on these images: the angle of impaction, how close the roots sit to the nerve that runs through your lower jaw, and whether there’s enough room for the teeth to come in normally. In some cases, a 3D scan provides more detail, particularly when the roots appear to wrap around or press against that nerve canal. These findings determine how the extraction will be approached and what level of sedation you’ll need.
Types of Impaction
Not all wisdom teeth present the same challenge. The type of impaction dictates how involved the surgery will be.
- Fully erupted: The tooth has come in completely and is visible in the mouth. This is the simplest scenario, often requiring only a standard extraction with forceps.
- Soft tissue impaction: The tooth has emerged from the jawbone but hasn’t broken through the gum. The surgeon needs to cut the gum tissue to access it.
- Partial bony impaction: Part of the tooth is visible, but a portion remains encased in jawbone. Bone removal is required.
- Full bony impaction: The tooth is completely hidden beneath both gum and bone. This is the most complex extraction, requiring the most tissue removal.
Anesthesia and Sedation Options
You’ll discuss sedation options before your surgery date. The choice depends on the complexity of the extraction, your anxiety level, and your medical history. Your vitals, medications, and overall health are reviewed beforehand to determine what’s safe.
With local anesthesia alone, you stay fully awake and alert. The injections numb only the surgical area, so you won’t feel pain but you’ll be aware of pressure and movement. This is common for simpler extractions.
Mild sedation uses nitrous oxide (laughing gas) alongside local anesthesia. You remain conscious but feel calm and somewhat detached from the procedure. Moderate sedation, sometimes called twilight sedation, uses medications delivered through an IV line to put you in a drowsy state between waking and sleeping. You’re technically still partially conscious but relaxed, pain-free, and unlikely to remember much afterward. This is one of the most popular choices for wisdom teeth removal. Heavy sedation and general anesthesia take things further, making you largely or completely unconscious. General anesthesia is typically reserved for more complex cases or patients with significant dental anxiety.
The Extraction Itself
Once the anesthesia takes effect, the surgeon follows a specific sequence. First, the gum tissue over the tooth is cut open with a scalpel to expose the tooth and the bone around it. If bone is covering or blocking access to the tooth root, the surgeon removes that bone using a surgical drill with a steady stream of water to keep the area cool.
For impacted teeth, the surgeon often divides the tooth into smaller sections rather than trying to pull it out whole. Sectioning makes it possible to remove the tooth through a smaller opening, which means less bone removal and less trauma to surrounding tissue. Each piece is lifted out individually. Once the tooth is fully removed, the socket is cleaned of any remaining bone or tooth fragments.
In rare cases where the roots sit dangerously close to the nerve in the lower jaw, a surgeon may recommend a coronectomy instead of full extraction. This involves removing only the crown (the top portion of the tooth) while intentionally leaving the roots in place. The goal is to avoid disturbing the nerve entirely. This approach is specifically reserved for high-risk patients whose imaging shows the roots in direct contact with the nerve canal.
Closing the Wound
After extraction, the surgeon places stitches to help the gum tissue heal properly. Dissolvable stitches are the most common choice for wisdom teeth removal. They break down on their own over several weeks, with the exact timeline depending on the stitch material and the extent of the surgery. In some cases, non-dissolvable stitches are used instead, which are removed at a follow-up appointment 7 to 10 days after surgery. Your surgeon will tell you which type you have before you leave.
Gauze is placed over each extraction site and you’ll be asked to bite down with gentle, steady pressure. This helps a blood clot form in the socket, which is essential for normal healing.
What Recovery Looks and Feels Like
Recovery follows a fairly predictable pattern. In the first 24 hours, expect a blood clot sitting in each socket, moderate swelling, and early bruising along the cheeks or jawline. Dark red blood on your gauze is normal for the first few hours. Pain is typically at its most intense during this initial window as the anesthesia wears off.
Between days 3 and 5, swelling usually peaks and then starts to come down. Pain eases noticeably for most people during this stretch. You may notice a white or yellowish film forming over the socket. This is fibrin, a protective layer your body produces as part of normal wound healing. It’s not pus.
From roughly day 6 through day 14, the gum tissue begins closing over the sockets. Redness fades, any scabbing sloughs off, and eating gets progressively easier. If you have dissolvable stitches, they’re typically gone or nearly gone by the end of this window.
Eating After Surgery
For the first 24 hours, stick to foods that require no chewing at all: smoothies, broth, yogurt, applesauce. Avoid anything hot in temperature, which can increase swelling and disrupt clot formation. Over the following week, you can gradually introduce soft foods that require minimal chewing.
Throughout recovery, avoid spicy foods, crunchy or crumbly textures, and anything with small seeds or grains that could lodge in the healing sockets. Skip alcohol, carbonated drinks, and caffeinated beverages for at least the first five days. Most people return to their normal diet around two weeks after surgery.
Nerve Injury Risk
The most talked-about risk of lower wisdom tooth removal is injury to the inferior alveolar nerve, which provides sensation to your lower lip and chin. When the tooth roots sit close to this nerve canal, the risk is real. A 2026 study published in the Journal of Oral and Maxillofacial Surgery found that among patients whose teeth were confirmed to be close to the nerve, about 17% experienced some degree of altered sensation at one month post-surgery. Many of these cases resolve within three months, though some persist longer or become permanent. This is one reason imaging is so important beforehand, and why coronectomy exists as an alternative for the highest-risk cases.
Other possible complications include dry socket (when the blood clot dislodges prematurely, exposing bone), infection, and prolonged swelling. Dry socket is the most common complication and typically causes a sharp increase in pain 3 to 5 days after surgery rather than the expected improvement.
