Wisdom teeth surgery is one of the most common oral procedures, with millions performed each year. It involves removing one or more of the third molars, the last teeth to come in at the back of your mouth, typically between ages 17 and 25. Whether you need the surgery depends on how your wisdom teeth are growing in and whether they’re causing problems or are likely to.
Why Wisdom Teeth Need to Come Out
Not everyone needs their wisdom teeth removed. The surgery becomes necessary when these teeth don’t have enough room to emerge properly. When a wisdom tooth is trapped beneath the gumline or only partially breaks through, it’s called impacted. Impacted wisdom teeth can press against neighboring molars, causing pain, crowding, or damage to otherwise healthy teeth. They can also create pockets where bacteria collect, leading to repeated infections in the surrounding gum tissue.
In some cases, a fluid-filled sac (cyst) forms around an impacted tooth and can damage the jawbone or nearby tooth roots. Even wisdom teeth that come in at an angle without causing immediate symptoms may be recommended for removal if X-rays show they’re heading toward problems down the line.
There are three levels of impaction, and each affects how involved the surgery will be. A soft tissue impaction means the tooth has risen above the jawbone but is still covered by gum tissue. A partial bony impaction means part of the tooth remains encased in bone. A complete bony impaction means the tooth is entirely buried in the jaw and isn’t visible at all, even when the gum is opened. The deeper the impaction, the more complex the extraction.
The Best Age for Surgery
Oral surgeons generally recommend removal between ages 15 and 22. At that age, the tooth roots aren’t fully formed and the jawbone is less dense, which makes extraction easier and recovery faster. Waiting until later in life increases the chance of complications because the roots grow longer, the bone hardens, and healing slows down. That said, people of any age can have the procedure if it’s needed.
What Happens During the Procedure
Most wisdom tooth removals take 45 minutes to an hour. Before the surgery begins, you’ll receive one of three types of anesthesia depending on the complexity of your case and your comfort level.
- Local anesthesia: Numbing injections near the extraction site. You’re fully awake and aware but shouldn’t feel pain, only pressure and movement.
- Sedation anesthesia: Medication delivered through an IV that makes you drowsy and relaxed. You won’t feel pain and likely won’t remember much of the procedure. This is the most common option for wisdom teeth removal, and you breathe on your own throughout.
- General anesthesia: Reserved for more complex cases. You’re completely asleep and placed on a ventilator to breathe for you.
Once you’re numb or sedated, the surgeon opens the gum tissue over the tooth, removes any bone blocking access, and extracts the tooth. Sometimes the tooth is divided into smaller pieces to make removal easier. The site is then cleaned, stitched closed (often with dissolving stitches), and packed with gauze to control bleeding.
Recovery Week by Week
The first 24 hours are the most uncomfortable. You’ll see a blood clot forming in each empty socket, along with moderate swelling and possibly bruising along the jaw and cheeks. Dark red blood on your gauze is normal for the first few hours. Plan to rest with your head elevated, apply ice packs in 20-minute intervals, and stick to very soft or liquid foods.
By days three to five, swelling peaks and then starts to subside. Pain eases noticeably for most people during this window. You may notice a white or yellowish film forming over the socket. This is a protective layer called fibrin, and it’s a sign of normal healing, not infection.
Between days six and fourteen, the gum tissue begins closing over the extraction sites. Redness fades, any scabbing sloughs off, and eating becomes much more comfortable. Dissolving stitches typically disappear on their own by the end of the second week. Most people return to normal activities within a week, though the sockets continue healing beneath the surface for several weeks after that.
What to Eat (and Avoid) Afterward
For the first few days, your diet should be soft foods served at room temperature or slightly cool. Good options include yogurt, mashed potatoes, scrambled eggs, smoothies, soup (cooled down), well-cooked pasta, mashed bananas or avocado, porridge, hummus, cottage cheese, and fish.
Avoid anything hard, crunchy, sticky, spicy, or very hot. That means no chips, nuts, popcorn, raw vegetables, caramel, chewing gum, or crusty bread. Skip carbonated and sugary drinks. Most importantly, don’t use straws. The suction can dislodge the blood clot in the socket and lead to a painful complication called dry socket. Avoid smoking or vaping for the same reason.
Dry Socket and Other Complications
Dry socket is the most common complication, affecting about 2% to 5% of all tooth extractions. It happens when the blood clot that normally protects the extraction site dissolves or gets dislodged too early, leaving the underlying bone exposed. The telltale signs are intense, throbbing pain that starts a few days after surgery (rather than improving), a visible empty hole where the clot should be, an unpleasant taste in your mouth, and bad breath. If you look at the socket and see white at the bottom, that’s exposed bone. Your dentist can treat dry socket by placing a medicated dressing in the socket to relieve pain while it heals.
Infection is another risk to watch for. The key signal is pain and swelling that gets worse around four to six days after surgery rather than better. A low-grade fever or discharge from the site can accompany it.
Nerve irritation is less common. The nerves that run through the lower jaw sit close to the roots of lower wisdom teeth, and they can be bruised during extraction. This may cause numbness or tingling in the lower lip, chin, or tongue. Temporary nerve issues occur in roughly 0.5% to 5% of cases, while permanent damage affects less than 1%.
How Much It Costs
The price varies significantly based on whether the teeth are impacted. A nonsurgical extraction of all four wisdom teeth (teeth that have fully erupted and can be pulled without cutting into bone) averages around $720 out of network. A surgical extraction of all four impacted wisdom teeth, including up to an hour of anesthesia, averages about $3,120 out of network. A single impacted tooth runs roughly $550.
Dental insurance typically covers 50% to 80% of the cost depending on your plan. Choosing an in-network oral surgeon can lower your out-of-pocket share considerably, since your copay is based on a discounted fee rather than the full price. In some situations, medical insurance (not just dental) may also cover part of the cost, particularly if the procedure is deemed medically necessary rather than preventive.
