A tooth extraction is a straightforward procedure that typically takes 20 to 40 minutes from start to finish. Your dentist or oral surgeon numbs the area, loosens the tooth from its socket, and removes it. What happens before, during, and after that removal depends on whether your tooth is fully visible above the gumline or partially trapped beneath tissue and bone.
How the Numbness Works
Before anything else, you’ll receive a local anesthetic injected near the tooth. These drugs block nerve impulses by preventing sodium ions from flowing through nerve channels, which stops pain signals from reaching your brain. You’ll still feel pressure and movement during the procedure, but no sharp pain. The numbness typically lasts one to three hours after the injection, gradually wearing off as blood flow carries the anesthetic away from the area.
For more complex extractions or patients with dental anxiety, sedation options are available. These range from nitrous oxide (laughing gas) that keeps you relaxed but awake, to IV sedation that puts you in a twilight state where you’re unlikely to remember the procedure. General anesthesia, where you’re fully unconscious, is less common but used for particularly difficult cases or multiple extractions.
Simple Extraction: Step by Step
A simple extraction is used when the tooth is fully visible above the gumline. Your dentist uses an instrument called an elevator, which looks like a small flat lever, to rock the tooth back and forth in its socket. This loosens the ligaments that anchor the tooth to the surrounding bone. Once the tooth has enough give, forceps grip it and ease it out. The whole removal often takes just a few minutes once you’re numb.
After the tooth is out, your dentist checks the socket to make sure no fragments remain. You’ll bite down on a piece of gauze to apply pressure, which helps a blood clot form in the empty socket. That clot is essential: it protects the exposed bone and nerve endings underneath, and it’s the foundation for all the healing that follows.
Surgical Extraction: What’s Different
A surgical extraction is necessary when a tooth hasn’t fully erupted through the gum, has broken off at the gumline, or has roots with unusual curves that prevent a clean pull. This is the standard approach for impacted wisdom teeth.
The surgeon makes a small incision in the gum tissue to expose the tooth. If bone covers part of the tooth, a drill or specialized instrument removes just enough bone to access it. In many cases, the surgeon sections the tooth into smaller pieces rather than trying to remove it whole, which requires less bone removal and causes less trauma to the surrounding area. Once all pieces are out and the socket is cleaned, the incision is closed with stitches. Some stitches dissolve on their own in a week or two; others need to be removed at a follow-up appointment.
What Happens Inside the Socket After Removal
Your body begins repairing the extraction site immediately. Within the first 24 to 48 hours, a blood clot fills the socket, acting as a biological bandage. This clot keeps bacteria and food debris out while new tissue grows underneath. Even though you can’t see it, gum tissue starts forming at the edges of the socket right away.
During the first week, the blood clot is gradually replaced by granulation tissue, a mesh of tiny blood vessels and connective tissue cells that serves as scaffolding for new growth. Between 7 and 21 days, the hole begins to visibly close as gum tissue regenerates across the surface. Underneath, early bone formation starts as soon as two weeks after extraction, though it takes six to eight weeks for new bone to substantially fill the socket. A complete seal of mature, mineralized bone forms around the 12th week on average. The broader reshaping of bone in the jaw continues for a year or more.
The First Few Days of Recovery
Most people experience the worst discomfort in the first two to three days. Swelling peaks around 48 hours and then gradually subsides. You can manage pain with over-the-counter options or whatever your dentist recommends. Applying ice to the outside of your cheek in 20-minute intervals helps reduce swelling during the first day.
For the first few days, stick to soft or liquid foods that require minimal chewing: yogurt, applesauce, broth-based soups, ice cream, and smoothies all work well. As you heal, you can add semi-solid foods like scrambled eggs, mashed potatoes, oatmeal, and soft pasta. Most people return to their normal diet within one to two weeks, though full healing of the deeper tissue takes several weeks.
The single most important thing you can do during recovery is protect the blood clot. Avoid using straws, spitting forcefully, smoking, or swishing liquid vigorously in your mouth for at least the first few days. Any suction in your mouth can pull the clot out of the socket.
Dry Socket: The Most Common Complication
When the blood clot dislodges or dissolves before the socket has healed, the result is a condition called dry socket. It leaves bone and nerves exposed to air, food, and bacteria, causing intense, radiating pain that typically starts two to four days after the extraction. The pain often spreads to the ear or temple on the same side.
Dry socket is more common after surgical extractions than simple ones, with surgical procedures carrying roughly three times the risk. Smoking is one of the strongest risk factors, increasing the odds more than sixfold. Poor oral hygiene raises the risk even further. If you develop dry socket, your dentist will clean the area and place a medicated dressing in the socket to soothe the exposed bone and promote healing. The pain usually resolves within a few days of treatment.
Signs of Infection to Watch For
Some swelling and mild discomfort are normal after an extraction. Infection, while uncommon, produces a distinct pattern: worsening pain after the first few days instead of improving, swelling that spreads or intensifies, a fever above 38°C (100.4°F), pus draining from the socket, difficulty opening your mouth, or trouble swallowing. These symptoms can appear within days of the procedure or sometimes a week or more later.
In rare cases, an untreated infection can spread to the floor of the mouth or deeper tissues of the neck, causing severe swelling that interferes with breathing and swallowing. This is a medical emergency. The vast majority of post-extraction infections are caught and treated long before reaching that point, typically with antibiotics and drainage if needed. If your pain is getting worse rather than better after the third day, or you develop any of the symptoms above, contact your dentist or surgeon promptly.
