Wisdom teeth — the third molars at the back of the mouth — typically appear between the ages of 17 and 25. They are a common source of dental problems and often the reason for a patient's first experience of dental surgery. But not every wisdom tooth needs to be removed. Understanding when extraction is necessary — and when it is not — can help you make an informed decision about your own dental health.
What Are Wisdom Teeth and Why Do They Cause Problems?
Wisdom teeth are the last teeth to emerge. Most people have four — one in each corner of the mouth. They are a remnant from our evolutionary past when our ancestors needed larger jaws and more teeth to chew a coarser diet.
The modern human jaw is typically too small to accommodate wisdom teeth comfortably. As a result, they frequently become impacted — meaning they do not have enough space to emerge properly and instead grow at an angle, push against the adjacent tooth, or remain partially or fully trapped beneath the gum.
When Does a Wisdom Tooth Need to Be Removed?
Removal is recommended when the wisdom tooth is causing current problems or is very likely to cause problems in the future. The main indications are impaction — the tooth is trapped and cannot emerge normally; pain and infection — a partially erupted wisdom tooth creates a flap of gum tissue that traps food and bacteria, leading to a condition called pericoronitis (infection around the wisdom tooth); damage to the adjacent tooth — an impacted wisdom tooth can push against the second molar, causing pressure damage, root resorption or decay in the back of that tooth; decay in the wisdom tooth itself — wisdom teeth are at the very back of the mouth and extremely difficult to clean, making them prone to cavities; and cyst formation — an impacted tooth can develop a fluid-filled cyst around it that damages the surrounding bone.
Your dentist will assess your wisdom teeth with X-rays to determine whether the position, angle and development of the tooth means removal is warranted.
When Can a Wisdom Tooth Be Left Alone?
Not every wisdom tooth needs removal. If a wisdom tooth has fully erupted into a good position, has a healthy adjacent tooth, can be properly cleaned and is not causing any pain, it can be monitored and left in place.
Some wisdom teeth remain fully impacted beneath the bone for a lifetime without causing any problems. These may be monitored with periodic X-rays rather than removed. The decision to remove or monitor should always be based on individual assessment — not a blanket recommendation.
The Wisdom Tooth Extraction Procedure
Wisdom tooth extraction is performed under local anaesthesia — you will feel pressure but not pain during the procedure. For anxious patients, sedation options can be discussed.
The complexity of the procedure depends on the position of the tooth. A fully erupted wisdom tooth is extracted similarly to any other tooth. An impacted wisdom tooth may require a small incision in the gum, and sometimes the tooth needs to be divided into sections for easier removal. This is routine for an experienced dentist.
The procedure typically takes 20–45 minutes per tooth. Most patients are surprised at how straightforward it is.
Recovery: What to Expect
Most patients recover within 3–5 days. The first 24 hours involve the most swelling and discomfort, which is managed with prescribed pain relief and anti-inflammatories. Swelling typically peaks on day 2 and then gradually subsides.
During recovery: rest on the day of the procedure; eat soft foods (yogurt, soup, scrambled eggs, mashed potato) for the first few days; avoid smoking, alcohol and using a straw for at least 48 hours, as these can dislodge the blood clot and cause a painful condition called dry socket; keep the area clean with gentle salt water rinses from day 2 onwards.
Dry socket — where the blood clot in the socket dislodges before healing is complete — is the most common complication. It causes significant pain from around day 3–4 and requires a dressing from the dentist. Smokers are significantly more prone to dry socket.
Is It Better to Remove Wisdom Teeth Early?
When removal is necessary, earlier is generally better. In younger patients (late teens to mid-twenties), the roots of the wisdom teeth are not yet fully formed and the surrounding bone is less dense, making the extraction easier and recovery faster. The procedure becomes more complex as patients age.
However, this does not mean wisdom teeth should be routinely removed as a preventive measure in all young people. Dr. Preethi assesses each patient individually — looking at the available space, the angle and position of the tooth and whether there are signs of current or likely future problems.

Frequently Asked Questions
The procedure itself is performed under local anaesthesia and is not painful — you will feel pressure but not pain. Post-procedure discomfort is manageable with prescribed pain relief and typically resolves within 3–5 days. Most patients find it significantly less uncomfortable than they expected.
For the first 2–3 days, stick to soft foods that require minimal chewing — yogurt, soup, mashed potato, scrambled eggs. Avoid very hot foods and drinks for the first 24 hours. Most patients return to a normal diet within 5–7 days.
Signs of an impacted wisdom tooth include pain or pressure at the back of the jaw, swelling around the back of the mouth, difficulty opening your mouth fully, and bad breath or an unpleasant taste from the area. An X-ray is the definitive way to assess whether a wisdom tooth is impacted and at what angle.
It is possible to remove all four wisdom teeth in one session, though this means a more significant recovery. Many patients choose to remove teeth on one side at a time so they can eat and function on the other side during recovery. Dr. Preethi will advise based on your specific situation.
