At a glance
Wisdom tooth extraction is a surgical procedure that removes one or more of the four third molars, the last teeth to grow at the very back of the mouth, usually in the late teens or early twenties.
Most people's jaws do not have enough room for these teeth. When a wisdom tooth cannot fully emerge, it becomes 'impacted', meaning it is trapped under the gum or against the neighbouring tooth. The surgeon cuts through the gum, removes any bone covering the tooth, and lifts or sections the tooth out. The goal is to stop the pain, infection, or crowding the tooth is causing before it damages the teeth beside it.
Medical Condition
Dentists and oral surgeons recommend extraction when a wisdom tooth is causing problems or is very likely to cause problems in the future.
- Impaction: the tooth is fully or partly stuck under the gum and cannot erupt normally.
- Pericoronitis: recurring infection and swelling of the gum flap that sits over a partially erupted tooth.
- Tooth decay or gum disease affecting the wisdom tooth or the molar next to it, because the position makes cleaning impossible.
- Pressure pain or crowding caused by the wisdom tooth pushing against adjacent teeth.
- A cyst or benign tumour forming around an unerupted tooth, which can hollow out the jaw bone.
- Preparation for orthodontic treatment (braces) when the wisdom tooth would undo the correction.
Not every wisdom tooth needs to come out. If the tooth has fully erupted, sits in a healthy position, can be cleaned properly, and causes no pain or crowding, most surgeons will leave it alone and monitor it over time.
- Fully erupted wisdom tooth with no decay, no gum disease, and enough space to clean.
- Patients with certain blood disorders or who take blood thinners may need their condition stabilised before any extraction is considered.
- Patients whose nearby nerves or blood vessels are at unusually high risk based on imaging may be counselled toward a more conservative approach.
Risks & Complications
Wisdom tooth extraction is a routine procedure, but like any surgery it carries recognised risks, and impacted teeth carry a higher risk than fully erupted ones.
- Pain and swelling around the socket for several days after surgery, which is normal but can be significant.
- Dry socket (alveolar osteitis): when the blood clot that protects the healing bone dissolves or dislodges too early, leaving the bone exposed and causing sharp, lasting pain. This is the most common complication.
- Infection in the socket, which may require antibiotics or additional treatment.
- Bleeding that is heavier or longer than expected.
- Temporary numbness or tingling in the lower lip, chin, tongue, or cheek if the inferior alveolar nerve or lingual nerve (nerves that run close to the lower wisdom tooth roots) is irritated during surgery. Permanent numbness is rare.
- Damage to the tooth next to the wisdom tooth during extraction.
- A small opening between the mouth and the sinus cavity above (oro-antral communication), which can occur when upper wisdom tooth roots sit close to the sinus. Most close on their own.
- Jaw stiffness (trismus) making it hard to open the mouth fully for a week or two.
- Rarely, a fracture of the jaw, most often in older patients whose bone is denser.
Preparation & Procedure
Preparation depends on whether you will have local anaesthesia (numbing of the area only), sedation (a relaxed, drowsy state), or general anaesthesia (fully asleep). Your surgeon's team will explain which approach suits your case.
If sedation or general anaesthesia is planned, you stop eating and drinking for at least six hours before the procedure. For local anaesthesia alone, fasting is usually not required, but follow your surgeon's instructions. Alcohol should be avoided for at least 24 hours beforehand, and smoking is best stopped for several days before surgery because it slows healing and raises the risk of dry socket.
Tell your surgeon about all medicines, supplements, and herbal products you take. Blood thinners, anti-inflammatory medicines, and some supplements may need to be paused for a period the surgeon specifies. Do not stop any prescribed medication without guidance.
Tests your team may arrange before the procedure include:
- A dental panoramic X-ray (OPG) or, for complex cases, a cone-beam CT scan to map exactly where the roots sit relative to the nerve and sinus.
- Basic blood tests to check clotting if you have a relevant medical history or are on blood thinners.
- A blood pressure check on the day.
On the day, the procedure typically follows these steps:
- You are seated in the surgical chair and a local anaesthetic is injected around the tooth. If sedation or general anaesthesia is used, this is given first.
- The surgeon makes an incision (a small cut) in the gum over the tooth if it is impacted.
- Bone covering the tooth is carefully removed where needed using a small drill.
- The tooth is loosened with instruments and, if necessary, divided into sections to make removal easier.
- The tooth or its sections are lifted out.
- The socket is cleaned and, in some cases, a bone graft material or medicated dressing is placed.
- The gum is closed with stitches that may dissolve on their own or need removal after about a week.
- Gauze is placed over the socket for you to bite down on to control bleeding.
Aftercare
Most patients go home the same day. Recovery after a simple extraction usually takes a few days, while a deeply impacted tooth can mean a week or more of noticeable discomfort. Your surgeon's team will give written instructions to take with you.
- Bite on the gauze pad for the time your surgeon advises to help the clot form. Replace it if soaking occurs.
- Do not rinse, spit forcefully, use a straw, or smoke for at least 24 hours. These actions can dislodge the clot and trigger dry socket.
- From the next day, rinse gently with warm salt water several times a day, especially after eating, to keep the socket clean.
- Swelling typically peaks around 48 to 72 hours after surgery. Applying a cold pack to the outside of the cheek in the first day helps reduce it.
- Eat soft foods such as soups, yoghurt, mashed foods, and eggs while the socket heals. Avoid hard, crunchy, or very hot foods.
- Pain relief medicines your surgeon prescribes or recommends should be taken as directed. If pain worsens sharply after a few days of improvement, contact your surgeon as this may signal dry socket or infection.
- Keep brushing your other teeth normally but stay away from the extraction site for the first day or two.
- If stitches are not the dissolving type, attend your follow-up appointment, usually around five to seven days after surgery, to have them removed.
- Avoid strenuous exercise for at least a few days as increased blood pressure can restart bleeding.
- Return to your surgeon promptly if you notice heavy bleeding that does not slow, spreading swelling, fever, or increasing rather than decreasing pain after the third day.
Cost & What Determines It
The price of wisdom tooth extraction varies widely because what sounds like the same procedure can differ enormously in complexity. Removing a tooth that has already erupted and has straight roots takes far less time and skill than surgically removing a deeply impacted tooth whose roots are curved around a nerve.
- Degree of impaction: a fully erupted tooth, a partially covered tooth, or a tooth completely buried in bone each require a different level of surgery, time, and equipment.
- Number of teeth removed: having all four extracted in one session versus one at a time changes the total cost significantly.
- Type of anaesthesia: local anaesthesia costs far less than intravenous sedation or general anaesthesia, which also requires an anaesthetist and a recovery room.
- Hospital or clinic class: a university dental hospital, a private day-surgery clinic, and a full surgical hospital all charge at different levels.
- Country where the procedure is done: surgical fees, anaesthesia costs, and facility charges vary greatly between countries.
- Imaging before surgery: a panoramic X-ray is inexpensive, while a cone-beam CT scan for complex root anatomy adds noticeably to the pre-operative cost.
- Bone grafting material placed in the socket after removal, if needed, adds to the cost.
- Any overnight stay required, which is uncommon but can happen after general anaesthesia or a very complex case.
- Post-operative medications such as antibiotics and pain relief.
A hospital package for wisdom tooth extraction may bundle the surgeon's fee, theatre or procedure room use, local anaesthesia, and a basic post-operative kit. Items that are often billed separately include the pre-operative CT scan, intravenous sedation or general anaesthesia fees, any bone graft material, additional medications, and follow-up consultations.
BPJS Kesehatan does not cover dental procedures performed abroad, and most Indonesian private health insurance policies also exclude overseas treatment. Patients who travel for this procedure typically pay out of pocket or rely on private international health insurance that explicitly covers overseas surgery. Before booking travel, ask the hospital for a detailed written cost estimate that breaks down each item. This protects you from unexpected bills after the procedure is done.
Frequently Asked Questions
How long does wisdom tooth extraction take?
Most wisdom tooth extractions take between 20 and 60 minutes, depending on how many teeth are removed and how deeply they are buried in the jaw. A tooth that has fully come through the gum is usually quicker to remove than one that is still hidden under the bone, which requires the surgeon to make a small cut and sometimes remove a little surrounding bone. Your surgeon will give you a better time estimate after looking at your X-rays.
How much does wisdom tooth extraction cost?
The cost depends on several factors specific to your case, including the number of teeth being removed, whether the teeth are impacted (stuck under the gum or bone), the type of anaesthesia used, and the class of the hospital or clinic. Getting a written estimate from the hospital, based on your X-rays and consultation, is the most reliable way to know what you will actually pay.
What kind of anaesthesia is used and will it hurt?
Most wisdom tooth extractions are done under local anaesthesia, which numbs the area completely so you feel pressure but not pain during the procedure. For more complex cases, or for patients who are very anxious, a dentist or surgeon may recommend sedation or general anaesthesia so you are fully asleep. After the numbness wears off, some soreness and swelling around the jaw is normal and is usually managed with pain relief prescribed by your doctor.
What warning signs should I watch for after the extraction?
Contact your doctor if you develop a fever, severe or worsening pain after the third day, heavy bleeding that does not slow down, or noticeable swelling that keeps growing rather than fading. A dry socket, which is when the protective blood clot over the wound is lost too early, is a common cause of sharp pain in the days after surgery and needs treatment from your dentist. Mild soreness, some swelling, and a little bleeding in the first 24 hours are normal and are not usually a cause for concern.
