Wisdom teeth are removed by a dentist or oral surgeon through a procedure that typically takes 45 minutes or less per tooth. The process involves numbing or sedating you, opening the gum tissue if needed, removing any bone blocking the tooth, and extracting the tooth in one piece or in sections. Whether you need one tooth out or all four, here’s what the full experience looks like from start to finish.
Why Wisdom Teeth Need Removal
Not every wisdom tooth needs to come out. The UK’s National Institute for Health and Care Excellence (NICE) recommends against removing wisdom teeth that aren’t causing problems, stating there’s no reliable evidence that preventive removal benefits patients. Removal should be limited to teeth showing clear signs of trouble.
The most common reasons for extraction include recurring infections in the gum tissue around a partially erupted tooth (called pericoronitis), decay that can’t be filled, cysts or tumors forming around the tooth, and damage to neighboring teeth. Wisdom teeth that are fully impacted, meaning trapped beneath the gum line or wedged against other teeth, often eventually develop one of these problems. Your dentist will use X-rays to assess the tooth’s position and determine whether extraction is necessary.
What Happens During the Procedure
The extraction process differs depending on whether the tooth has fully come through the gum or is still partially or completely buried. A tooth that’s already visible in the mouth can often be loosened and pulled with forceps, similar to any other tooth extraction. This is called a simple extraction.
Surgical extraction is more involved. The surgeon makes an incision in the gum to expose the tooth, then removes small amounts of bone surrounding it if necessary. In many cases, the tooth is cut into smaller pieces so it can be taken out through a smaller opening. This sounds more dramatic than it feels, since you’ll be numb or sedated throughout. Once the tooth is out, the surgeon places stitches to close the gum tissue. These stitches typically dissolve on their own within a week or two.
Anesthesia and Sedation Options
You’ll have one of three options for staying comfortable during the procedure:
- Local anesthesia: Numbing injections near the extraction site. A topical gel is applied to your gums first so you barely feel the needle. You’re fully awake but feel no pain, only pressure.
- IV sedation: Medication delivered through a vein in your arm that makes you drowsy and relaxed. You won’t feel pain and likely won’t remember much of the procedure. You still breathe on your own, and your gums are also numbed with local anesthesia.
- General anesthesia: Reserved for complex cases. You breathe in medication or receive it through an IV and fall completely asleep. Unlike IV sedation, general anesthesia requires a ventilator to help you breathe.
Most wisdom tooth removals use IV sedation. It offers the comfort of feeling like you slept through the whole thing without the added risks of general anesthesia. Your surgeon will recommend the best option based on how many teeth are coming out, how deeply impacted they are, and your anxiety level.
Preparing for Surgery
If you’re having IV sedation or general anesthesia, you’ll need to fast beforehand. Your surgeon’s office will give you specific timing for when to stop eating and drinking, which is typically at least six to eight hours before the appointment. You’ll also get instructions about which of your regular medications to take or skip that morning.
Plan to have someone drive you home. Sedation and anesthesia leave you groggy for several hours, and you won’t be safe behind the wheel. Wear comfortable clothes with short sleeves so the IV can be placed easily. Stock your kitchen with soft foods before the procedure so you’re not scrambling afterward.
The Recovery Timeline
Healing follows a predictable pattern over several weeks:
During the first two days, a blood clot forms in each empty socket. This clot is critical. It protects the exposed bone and nerve endings underneath and serves as the foundation for new tissue growth. You’ll have the most swelling and discomfort during this window. Applying ice packs in 20-minute intervals helps keep swelling down.
By days three through five, a white or yellowish film starts covering the socket. This is a normal protective layer of healing tissue, not a sign of infection. Pain typically begins easing during this stage, though the area will still be tender.
Between days six and fourteen, the gum tissue starts closing over the extraction sites. Most people feel well enough to return to normal activities within a week, though the sockets aren’t fully healed yet. By weeks three and four, the socket fills in with new tissue and the gum reshapes itself. Full bone remodeling beneath the surface continues for several months.
Managing Pain After Extraction
Over-the-counter pain relievers work well for most people. The American Dental Association’s clinical guidelines recommend starting with an anti-inflammatory like ibuprofen (400 mg) or naproxen sodium (440 mg), taken alone or combined with acetaminophen (500 mg). This combination targets pain through two different pathways and is more effective than either medication alone.
For daily limits, don’t exceed 2,400 mg of ibuprofen, 1,100 mg of naproxen sodium, or 4,000 mg of acetaminophen in a 24-hour period. Taking the first dose before the numbness wears off helps you stay ahead of the pain rather than chasing it.
The ADA specifically recommends against opioid painkillers for simple extractions and considers them a last resort even after surgical extractions. In the rare cases where anti-inflammatories aren’t enough, a short course of opioid medication may be added, but this rarely lasts more than three days.
What to Eat and Avoid
Stick to soft foods for the first several days. Smoothies (eaten with a spoon), yogurt, mashed potatoes, scrambled eggs, and blended soups all work well. Keep soups lukewarm or cool rather than hot, since heat can irritate the extraction sites. Avoid fruits with small seeds like strawberries and blackberries, as seeds can lodge in the open sockets and cause infection.
The most important rule: do not use a straw. The suction can dislodge the blood clot from the socket, leading to a painful complication called dry socket. Avoid straws for at least a week, and don’t spit forcefully, smoke, or do anything else that creates suction in your mouth.
Dry Socket and Other Complications
Dry socket is the most common complication after wisdom tooth removal. It happens when the blood clot breaks loose or dissolves too early, leaving the bone and nerves exposed. The result is intense, throbbing pain that typically starts two to four days after extraction and can radiate up to your ear and eye on that side.
The overall incidence of dry socket after tooth extractions runs around 1 to 4%, but the rate climbs significantly for wisdom teeth, particularly lower ones. One study of over 1,500 patients found a dry socket rate of about 5%. Lower wisdom teeth carry a risk roughly ten times higher than upper ones. Smoking, using straws, and taking oral contraceptives all increase your chances.
If you develop dry socket, your surgeon will clean the socket and place a medicated dressing inside it to relieve pain and promote healing. It’s uncomfortable but treatable, and the pain usually improves within a few days of treatment.
Other potential complications include infection (watch for fever, worsening swelling after day three, or pus), temporary numbness in the lower lip or tongue from nerve irritation during lower wisdom tooth removal, and stiffness in the jaw muscles that limits how wide you can open your mouth for a week or two. Permanent nerve changes are uncommon but are more likely when the roots of lower wisdom teeth sit very close to the nerve that runs through the jawbone.
