A wisdom tooth should be removed when it causes repeated pain or infection, decays, damages the tooth in front of it, or is linked to a cyst or gum disease. Healthy, fully erupted wisdom teeth that you can clean well can be left alone. Extraction is done under local anaesthesia, takes roughly 20–60 minutes, and most people feel back to normal in 3–5 days.
What are wisdom teeth?
Wisdom teeth, or third molars, are the four back teeth at the far corners of the upper and lower jaws. Many jaws do not have enough room for them. When a tooth cannot come up straight, it may stay buried or tilt against the tooth in front, which dentists call an impacted wisdom tooth. Not everyone has all four, and some people have none.
When removal is needed
Being an impacted or misplaced tooth is not, by itself, a reason for surgery. Your dentist recommends extraction when the tooth is causing or is likely to cause a problem.
| Problem | What happens | Typical signs |
|---|---|---|
| Pericoronitis (gum infection) | Food and bacteria collect under the gum flap over a partly erupted tooth | Swollen, tender gum at the back, bad taste, pain on opening the mouth |
| Decay in the wisdom tooth | The tooth is hard to reach and clean, so cavities form | Toothache, food packing, a visible hole |
| Damage to the next molar | A tilted wisdom tooth pushes on or traps food against the second molar | Decay or bone loss behind the second molar on X-ray |
| Cyst or growth around the tooth | A fluid-filled sac can form around a buried tooth and slowly damage the jaw bone | Often no symptoms; found on X-ray |
| Gum disease around the tooth | Deep pockets form and bacteria build up | Bleeding gums, bad breath, loose feeling |
| Before braces or other treatment | Removal is sometimes advised when space or planning requires it | Decided with the orthodontist |
No. If the tooth is fully erupted, healthy, can be brushed and flossed properly and looks normal on X-ray, it can be kept and reviewed regularly. Removing a wisdom tooth "just in case" is not always necessary, so ask your dentist to show you the reason on the X-ray.
Assessment and X-ray
Before any surgery, the dentist examines your mouth and takes an X-ray, usually a panoramic OPG. It shows how deep the tooth is, its angle, the roots and how close it lies to the jaw nerve (the inferior alveolar nerve) and, for upper teeth, the sinus. In complex cases a 3D scan (CBCT) may be advised for safer planning.
Tell your dentist about your health history and medicines. This matters especially if you have diabetes, high blood pressure, a heart condition, bleeding problems, or take blood thinners. Never stop a prescribed medicine on your own. Also mention if you are pregnant, as elective removal is usually postponed.
How the extraction is done
- Numbing Local anaesthetic is injected around the tooth. Once it takes effect, you feel pressure and movement but not sharp pain.
- Access For a simple case the tooth is loosened and lifted out. For an impacted tooth, the gum is opened and a small amount of bone may be removed to expose the tooth.
- Sectioning if needed An impacted tooth is often divided into pieces so it can be removed through a smaller opening, which protects the surrounding bone.
- Cleaning the socket The area is cleaned of debris and infected tissue and rinsed.
- Stitches The gum is stitched if it was opened. Dissolving stitches are common; others are removed after about a week.
- Gauze and instructions You bite on a gauze pad to control bleeding and receive written aftercare advice and prescriptions.
Simple vs surgical extraction
| Simple extraction | Surgical extraction | |
|---|---|---|
| Tooth position | Fully erupted and visible | Partly erupted or buried, tilted or with curved roots |
| Gum incision and stitches | Usually not needed | Usually needed |
| Bone removal or sectioning | No | Often |
| Usual time per tooth | About 15–30 minutes | About 30–60 minutes or more |
| Swelling and discomfort | Mild to moderate | Moderate, peaks around day 2–3 |
| Return to routine | About 2–4 days | About 3–5 days |
Times are typical ranges. Your own case can be quicker or longer. The cost depends on the position of the tooth, whether it is simple or surgical, how many teeth are removed and the imaging needed, so a fair estimate is only possible after an examination.
Risks and complications
Wisdom tooth removal is a common and generally safe procedure, but you should know the possible problems.
- Swelling, bruising and stiff jaw. Expected. Swelling usually peaks at 48–72 hours and then settles.
- Bleeding. Slight oozing for the first day is normal.
- Dry socket. A lost blood clot exposes the bone and causes severe throbbing pain, often 2–4 days after surgery. It is more common with lower teeth, surgical extractions and smoking or tobacco use, and it is treated by cleaning the socket and placing a medicated dressing.
- Infection. Rare with good aftercare, and treated with cleaning and, if needed, antibiotics.
- Numbness of the lip, chin or tongue. Lower wisdom tooth roots can lie close to nerves. Numbness is usually temporary, and permanent change is uncommon. The X-ray helps your dentist plan around this.
- Sinus opening. Upper tooth roots can sit close to the sinus floor. If a small opening forms, it is managed by your dentist.
Recovery timeline
| When | What you may feel | What to do |
|---|---|---|
| First 24 hours | Numbness wearing off, oozing, tenderness | Bite on gauze, rest, cold compress, cool soft foods, do not rinse or spit forcefully |
| Days 2–3 | Swelling and stiffness at their worst, mild bruising | Continue medicines as advised, start gentle salt-water rinses, keep the head raised while sleeping |
| Days 4–7 | Swelling and pain clearly reducing | Return to work or college, gradually widen your diet, stitch removal if needed |
| Weeks 2–4 | Gum closing over the socket, occasional tenderness | Resume normal cleaning and exercise, attend the review visit |
| Months 2–3 | Socket fills with new bone | Nothing special; keep up routine dental check-ups |
Aftercare do's and don'ts
Do
- Bite firmly on the gauze for 30–45 minutes, then replace it if it is still oozing.
- Apply a cold pack on the cheek for 15 minutes at a time on day 1–2.
- Eat cool, soft food such as curd, khichdi, dal, mashed banana and smoothies eaten with a spoon.
- Start gentle warm salt-water rinses after 24 hours, especially after meals.
- Brush your other teeth normally and avoid the surgical area for the first day.
- Take the medicines exactly as prescribed and finish any course you are given.
- Sleep with your head propped on an extra pillow.
Don't
- Do not smoke, chew paan, gutkha or tobacco, or drink alcohol for at least 3–5 days. Longer is better.
- Do not use a straw or spit forcefully in the first 24 hours.
- Do not poke the socket with your tongue, fingers or a toothpick.
- Avoid hot, spicy, crunchy or hard food in the first days.
- Avoid heavy exercise and bending for about a week.
- Do not apply heat on the cheek in the first 48 hours.
When to call the dentist
- Bleeding that continues after 30 minutes of firm pressure on fresh gauze
- Pain that gets worse after day 3, with a bad taste or smell (possible dry socket)
- Swelling that keeps increasing after day 3, or fever
- Pus from the socket or a bad taste that does not clear
- Numbness of the lip, chin or tongue that is not improving
- A socket area or ulcer that has not healed after 3 weeks
Go to a hospital emergency immediately if you have difficulty breathing or swallowing, or swelling that spreads to the neck or around the eye.

Frequently asked questions
Is wisdom tooth extraction painful?
The area is fully numbed with local anaesthesia, so you feel pressure and movement but not sharp pain during the procedure. Soreness and swelling are normal for the first 2 to 3 days afterwards and are controlled with the medicines your dentist prescribes and a cold compress.
How long does wisdom tooth removal take?
A simple extraction of a fully erupted tooth often takes 15 to 30 minutes. A surgical extraction of an impacted tooth can take 30 to 60 minutes or more, depending on its position and how many teeth are removed.
How many days of rest do I need after wisdom tooth removal?
Most people return to desk work or college in 2 to 4 days after a simple extraction and in 3 to 5 days after a surgical one. Avoid heavy exercise, swimming and travel on rough roads for about a week.
What is dry socket and how can I avoid it?
Dry socket occurs when the blood clot in the empty socket is lost or fails to form, exposing the bone. It causes severe, throbbing pain that usually starts 2 to 4 days after extraction and may bring a bad taste or smell. To avoid it, do not smoke, chew tobacco or paan, use a straw, spit forcefully or rinse vigorously in the first 24 hours, and follow your dentist's instructions.
Do I have to remove a wisdom tooth that does not hurt?
Not always. A wisdom tooth that has fully erupted, is healthy, can be cleaned properly and shows no disease on X-ray can be left and monitored. Removal is advised when there is repeated infection, decay, damage to the next tooth, cysts, or gum disease around it.
