Wisdom tooth removal starts with numbing or sedating you, then loosening the tooth from its socket using specialized instruments, and finally lifting it out. The whole process typically takes 20 to 45 minutes per tooth, though impacted teeth buried under gum tissue or bone take longer. Here’s what actually happens at each stage.
Before the Procedure
If you’re getting IV sedation or oral sedation, you’ll need to stop eating and drinking (including water) for eight hours before your appointment. If you’re only getting local anesthesia with no sedation, a light meal two to three hours beforehand is fine. Either way, avoid alcohol for at least 24 hours prior and skip over-the-counter blood thinners like aspirin unless your dentist specifically tells you otherwise.
Bring a list of every medication you take, especially blood thinners, insulin, or heart medications. If you were prescribed antibiotics or anti-anxiety medication ahead of the procedure, take them exactly as directed. And if you’re getting sedation, arrange a ride home because you won’t be safe to drive.
How You’re Numbed or Sedated
There are three options, and which one you get depends on how complex the extraction is and your comfort level.
- Local anesthesia. You get one or more injections near the tooth being removed. A numbing gel is applied to your gums first so the needle is more comfortable. You’re fully awake during the procedure but feel no pain, only pressure.
- IV sedation. Medicine goes through an IV line in your arm, making you feel drowsy, calm, and unlikely to remember much afterward. Your gums are also numbed once you’re relaxed. You breathe on your own the entire time. This is the most common approach for wisdom tooth removal.
- General anesthesia. Reserved for more complex cases. You breathe in medication through a mask or receive it through an IV, and you fall completely asleep. Unlike sedation, general anesthesia requires a ventilator to help you breathe.
Simple Extraction: Teeth Above the Gumline
When a wisdom tooth has fully erupted through the gum, the removal is relatively straightforward. After the area is numb, the dentist uses an instrument called an elevator, a small lever-shaped tool that fits into the narrow space between the tooth and the surrounding bone. By wedging it in and applying controlled rocking and twisting motions, the elevator stretches the ligament fibers holding the tooth in place and loosens it within the socket.
Some offices use a newer style of elevator with two prongs that grip the tooth at the gumline. One prong anchors against the bone while the other pushes the tooth side to side, expanding the socket walls. The dentist alternates between rocking the tooth front-to-back and side-to-side, spending about 30 seconds with each instrument, until the tooth moves freely.
Once the tooth is loose enough, extraction forceps (essentially precision pliers shaped to grip a tooth’s crown) are placed around it. The dentist rocks the tooth back and forth a few more times, then lifts it out of the socket. You’ll feel pressure during this part but not pain. The whole process for a simple extraction can take as little as five to ten minutes per tooth.
Surgical Extraction: Impacted Teeth
Impacted wisdom teeth are partially or fully trapped beneath the gum tissue, sometimes buried in the jawbone. These require a surgical approach. After numbing or sedating you, the oral surgeon makes an incision in the gum tissue to expose the tooth and any bone covering it. If bone is blocking access, a small amount is carefully removed using a drill.
Here’s where things differ most from a simple pull: impacted teeth often can’t come out in one piece. The surgeon sections the tooth, cutting it into two or three smaller fragments that can be removed individually through a smaller opening. This reduces the amount of bone that needs to be taken out and puts less stress on the surrounding jaw. Each fragment is loosened with elevators and lifted out separately.
After all the pieces are removed, the surgeon cleans the socket of any debris, then stitches the gum tissue closed. Most stitches used today are dissolvable and disappear on their own within seven to ten days.
What Recovery Looks Like
Healing follows a predictable pattern. In the first 24 hours, blood clots form in the empty sockets. These clots are critical because they protect the exposed bone and nerve endings underneath, so anything that could dislodge them (drinking through a straw, spitting forcefully, vigorous rinsing) needs to be avoided. Swelling in your mouth and cheeks peaks around day two or three, then starts improving. By seven to ten days, jaw stiffness and soreness typically resolve and any dissolvable stitches are gone.
For the first few days, stick to soft or liquid foods: yogurt, applesauce, broth-based soups, ice cream, and smoothies (eaten with a spoon, not a straw). As you start feeling better, you can move to semi-solid options like oatmeal, mashed potatoes, scrambled eggs, very soft pasta, and finely cut fish or meat. Avoid anything acidic like oranges and tomatoes, carbonated drinks, hard seeds and nuts, popcorn, spicy foods, sticky candy, and hot beverages, all of which can irritate the extraction sites or get lodged in the sockets. If food does get stuck, rinse gently with warm salt water rather than poking at it or using mouthwash.
Risks Worth Knowing About
The most talked-about complication is dry socket, which happens when the blood clot in an extraction site breaks down or gets dislodged too early, leaving the bone exposed. It affects about 2% to 5% of all tooth extractions and causes a deep, throbbing pain that usually starts two to four days after surgery. It’s treatable but unpleasant, and it’s the main reason you’ll be told repeatedly not to use straws or smoke during recovery.
Nerve injury is the other risk people worry about, particularly for lower wisdom teeth. The nerve that provides sensation to your lower lip, chin, and tongue runs through the jawbone close to where lower wisdom teeth sit. In patients whose teeth are near this nerve (identified on imaging beforehand), the overall risk of some nerve disturbance is roughly 9.5%, rising to about 15% in high-risk cases where the tooth root is very close to or wrapping around the nerve. The reassuring part: most of these injuries are temporary, with sensation returning within three to six months. Permanent numbness occurs in a much smaller fraction of cases.
Infection, prolonged bleeding, and stiffness in the jaw joint can also occur but are less common and generally manageable with follow-up care.
How Many Teeth Come Out at Once
Most oral surgeons remove all four wisdom teeth in a single session when sedation is being used. This means one recovery period instead of multiple, and it’s the standard recommendation for most patients. If only one or two wisdom teeth are causing problems and the others look healthy on imaging, your dentist may suggest removing just those. Patients who prefer local anesthesia only sometimes choose to have teeth removed in separate visits to keep each appointment shorter and more comfortable.
