Wisdom Teeth Removal: What to Expect Before, During, and After
When Wisdom Teeth Need to Come Out
Third molars — wisdom teeth — are the last teeth to develop, typically emerging between ages 17 and 25. Problems occur when there isn't enough room in the jaw for them to erupt properly.
Extraction is typically recommended when wisdom teeth are:
- Impacted: Fully or partially trapped beneath the gumline or against adjacent teeth
- Angled incorrectly: Pushing against the second molar, risking damage or misalignment
- Causing pericoronitis: Recurring infection around a partially erupted tooth
- Decayed: In a position too difficult to clean or restore properly
- Developing cysts: Fluid-filled sacs around the impacted tooth that can damage bone
Who Performs the Extraction
Simple erupted wisdom tooth extractions can be performed by a general dentist. Impacted extractions — particularly those involving teeth near the inferior alveolar nerve — are typically referred to an oral and maxillofacial surgeon (OMS). If all four teeth need removal at once, an OMS under IV sedation or general anesthesia is standard.
What Happens During the Procedure
- Anesthesia: Local anesthetic numbs the area. IV sedation or general anesthesia is available for complex cases or anxious patients.
- Tissue and bone access: For impacted teeth, the surgeon makes an incision in the gum and may remove small amounts of bone covering the tooth.
- Sectioning: Impacted teeth are often divided into sections for easier removal.
- Extraction: The tooth is loosened with elevators and removed with forceps.
- Closure: The socket is cleaned, and the incision is sutured (usually with dissolvable sutures).
Recovery Timeline
Day 1: Bleeding, swelling, and soreness are normal. Bite on gauze pads to control bleeding. Rest with your head elevated. Start prescription pain medication before the local anesthetic wears off.
Days 2–3: Peak swelling. Soft foods only — yogurt, smoothies, mashed potatoes, scrambled eggs. No straws, no smoking, no spitting.
Days 3–5: Swelling begins to subside. Most patients resume light activity and work.
Week 2: Sutures dissolve or are removed. Sockets continue to close.
Warning Signs to Watch For
- Intensifying pain after day 3 (possible dry socket)
- Fever above 101°F
- Difficulty swallowing or breathing
- Excessive swelling or pus from the socket
- Numbness persisting beyond 24 hours (rare nerve involvement)
Contact your surgeon immediately if any of these occur. Find an oral surgeon or dentist near you on The Dentist Ranker.
Frequently Asked Questions
- Do all wisdom teeth need to be removed?
- No. Wisdom teeth that fully erupt, have room to function, and are easy to clean do not need to be removed. Extraction is recommended when they are impacted (unable to fully erupt), growing at an angle that damages adjacent teeth, causing recurring infection, or creating decay that is difficult to treat. Your dentist or oral surgeon will evaluate with a panoramic X-ray.
- How long does wisdom tooth recovery take?
- Most patients recover well enough to return to normal activity in 3–5 days. Complete soft tissue healing takes 2–3 weeks. Bone remodeling continues for several months but is not typically felt. Recovery is slower for impacted teeth requiring bone removal than for simple erupted extractions.
- What is dry socket and how do you prevent it?
- Dry socket (alveolar osteitis) occurs when the blood clot that forms after extraction is dislodged or dissolves before healing is complete, exposing the underlying bone. It causes significant pain starting 2–4 days post-extraction. Prevent it by avoiding straws, smoking, spitting forcefully, and hard foods for the first 72 hours. If you experience intense pain after day 3, contact your dentist — dry socket is treated by packing the socket with a medicated dressing.
