A tooth extraction starts with numbing the area, then loosening the tooth from the bone and ligament that hold it in place, and finally pulling it out with specialized instruments. The whole process for a simple extraction often takes under 20 minutes. But the specifics vary depending on whether the tooth is fully visible above the gumline or trapped beneath bone and tissue, which determines whether you’ll need a simple or surgical extraction.
Simple vs. Surgical Extraction
If your tooth is fully visible and accessible, you’ll get a simple extraction. The dentist works with elevators and forceps to loosen and remove the tooth without cutting into gum tissue or bone. Most routine extractions for damaged, decayed, or loose teeth fall into this category.
A surgical extraction is necessary when the tooth isn’t fully accessible. If gum tissue covers the tooth, the surgeon makes an incision to expose it. If bone covers part of the tooth, some of that bone is removed as well. Impacted wisdom teeth are the most common reason for surgical extractions, but badly broken teeth where little remains above the gumline also require this approach. Surgical extractions typically involve sutures afterward to close the incision and support healing.
What Happens Before the Extraction
Your dentist will take X-rays before removing any tooth. Periapical X-rays, the small films that capture one or two teeth, are the standard imaging method. They show root shape, length, curvature, and any infection at the root tip. For more complex cases, especially impacted lower wisdom teeth, a panoramic X-ray gives a wider view of the jawbone and lets the dentist assess how close the roots sit to important structures like the nerve running through the lower jaw or the sinus cavities above the upper molars.
Cone beam CT scans, which produce 3D images, are used less frequently but offer the most detailed view when a tooth’s roots are unusually close to a nerve canal or when the anatomy is complicated.
How Numbing Works
Before anything touches your tooth, the area is fully numbed. Most dentists start with a topical anesthetic, a gel or spray applied directly to the gum. This kicks in within about 30 seconds and reaches full effect in two to three minutes, dulling the surface so you barely feel the injection that follows.
The injection delivers a local anesthetic, most commonly from a class of drugs called amides, which block nerve signals in the area. These last considerably longer than older types of numbing agents. Depending on which drug is used, the numbness in your soft tissue (lips, cheeks, tongue) can persist for three to five hours, or in some cases up to nine hours with longer-acting formulations. You’ll feel pressure during the extraction but no sharp pain.
For surgical extractions or patients with dental anxiety, sedation options range from nitrous oxide (laughing gas) to oral sedatives to IV sedation, where you’re conscious but deeply relaxed and unlikely to remember much of the procedure.
The Step-by-Step Process
Once the area is numb, the dentist begins loosening the tooth. The first instrument used is typically a straight elevator, a flat-tipped tool wedged between the tooth and surrounding bone. The dentist works the elevator around the top of the tooth in small rocking motions, pushing it deeper along the root to sever the periodontal ligament, the fibrous tissue that anchors the tooth to the jawbone. This creates space and begins to free the tooth.
For multi-rooted teeth or stubborn roots, a Cryer elevator may be used. This has a curved, triangular tip that generates stronger rotational force, essentially twisting the tooth along its path of least resistance. In surgical cases, the dentist may also section the tooth, cutting it into smaller pieces that are easier to remove individually.
Once the tooth is sufficiently loosened, forceps grip the crown or remaining structure. The dentist rocks the tooth back and forth to widen the socket, then lifts it out. After removal, the socket is inspected and sometimes cleaned of any debris or infected tissue. For surgical extractions, sutures close the site. Absorbable sutures dissolve on their own over time, while non-absorbable types (like silk or nylon) need to be removed at a follow-up appointment, usually about a week later. Some dentists use tissue adhesives as an alternative to stitches.
What Recovery Looks Like
Healing follows a predictable pattern. In the first 24 hours, a blood clot forms in the empty socket. This clot is essentially a natural bandage protecting the exposed bone and nerve endings underneath. It’s the single most important part of early healing, and everything you do in the first week revolves around keeping it intact.
By days four and five, granulation tissue begins forming in the socket. This pinkish tissue acts as a foundation layer, filling the space where the tooth was and setting the stage for new tissue growth. The gum tissue gradually closes over the socket during the first two weeks. Deeper inside, bone regeneration takes longer. New bone begins filling the socket around one month post-extraction, with the process continuing for one to three months.
Protecting the Clot After Extraction
The biggest threat to smooth healing is losing that blood clot. Suction in your mouth can dislodge it, which is why you should avoid using straws for at least seven days after a simple extraction. If you had a surgical extraction or wisdom tooth removal, your dentist may recommend waiting 10 to 14 days. The same rule applies to smoking and vaping, both of which create suction and also introduce chemicals that impair healing.
Stick to soft foods for the first few days, avoid rinsing vigorously, and don’t poke at the socket with your tongue or finger. Gentle saltwater rinses can start 24 hours after the procedure to keep the area clean.
Dry Socket: The Most Common Complication
When the blood clot dissolves or gets dislodged too early, the result is dry socket, a condition where bone and nerves are left exposed to air, food, and bacteria. It causes a deep, radiating pain that typically starts two to four days after the extraction and is noticeably worse than the normal post-extraction soreness.
Overall, dry socket affects roughly 0.5% to 5% of all extractions. But lower wisdom teeth are a different story: around 30% of lower wisdom tooth extractions develop dry socket, far more than all other extraction sites combined. Several factors raise your risk. Women are affected more often than men, particularly those taking oral contraceptives, because hormonal changes affect how blood clots form and break down. Tobacco use, poor oral hygiene, and a difficult extraction also increase the odds. Treatment involves your dentist placing a medicated dressing in the socket to relieve pain while the tissue heals underneath.
Nerve Injury Risk
Lower wisdom teeth sit close to the inferior alveolar nerve, which provides sensation to your lower lip, chin, and gums. Extraction can sometimes bruise, stretch, or damage this nerve. The reported incidence ranges from about 0.35% to 8.4%, depending on the complexity of the case and the study.
Most nerve injuries are temporary. Numbness or tingling in the lip and chin area gradually resolves over weeks to months. Permanent nerve injury, defined as sensory changes lasting longer than six months, occurs in less than 1% of cases. One large study tracking patients over time found that while 48 patients experienced nerve-related numbness at one month, 20 still had symptoms at 18 to 24 months. Your dentist evaluates nerve proximity on your X-rays beforehand, and if the roots appear very close to the nerve canal, they may order a 3D scan or adjust the surgical approach to reduce risk.
Socket Preservation After Extraction
Once a tooth is removed, the surrounding jawbone begins to shrink. This is a natural process, but it can create problems if you’re planning to get a dental implant later or if the extraction site is in a visible area like the front of your mouth. Socket preservation involves placing a bone graft material into the empty socket at the time of extraction to maintain the bone’s shape and volume.
Not every extraction needs this. Socket preservation is recommended in three main situations: when the extraction is in an area that affects your smile, when the surrounding bone walls are severely damaged, and when implant placement will be delayed rather than done immediately. If you’re considering an implant down the road, ask your dentist about socket preservation before the extraction, since it’s much easier to maintain bone than to rebuild it later.
