Wisdom Tooth Removal: When to Act and What to Expect
Wisdom teeth (third molars) are the last to emerge — and the most likely to cause problems. Dr. Anshalika explains when extraction is necessary, what the procedure involves, and how to recover quickly.

Why Wisdom Teeth Cause Problems
Wisdom teeth — the third molars — typically emerge between the ages of 17 and 25. Modern human jaws have gradually become smaller over thousands of years, and most people simply lack sufficient space at the back of the mouth for these four additional teeth. When a wisdom tooth cannot fully erupt in its correct position, it becomes 'impacted' — either partially erupted (partially impacted, with some crown visible through the gum) or remaining entirely trapped under the gum or bone (fully impacted). An impacted tooth creates a persistent pocket between the tooth and overlying gum that traps food debris and bacteria, leading to infection (pericoronitis), decay in the adjacent second molar, cyst formation around the crown, or pressure-related crowding of the other teeth.
Signs You Need Your Wisdom Tooth Assessed
You should seek evaluation if you experience persistent pain or pressure at the back of your jaw, swelling or redness of the gum behind the last molar, difficulty opening your mouth fully (trismus), a bad taste or persistent bad breath that doesn't resolve with brushing, pain spreading to the ear or cheek, or recurring infections around the wisdom tooth area. Even without symptoms, a dentist or oral surgeon may advise evaluation based on X-ray findings. An OPG (dental panoramic X-ray) maps the position, angle, root formation, and proximity to the inferior alveolar nerve — essential information for safe extraction planning.
The Extraction Procedure
Wisdom tooth removal is performed under local anaesthesia — you remain awake and comfortable, feeling pressure but no pain. For partially or fully impacted teeth, a small incision in the gum may be needed to access the tooth, and the tooth is often divided into sections to allow safe removal without disturbing surrounding structures. The socket is cleaned and closed with dissolving sutures. Simpler partially impacted cases take 15–20 minutes. Complex fully bony-impacted cases, particularly those near the inferior alveolar nerve, require more careful technique and may take longer. Dr. Anshalika's surgical training means even the most complex impactions are handled with the precision and nerve-awareness they demand.
Recovery After Wisdom Tooth Surgery
Some degree of swelling, bruising, and discomfort is expected for 3–5 days after the procedure. Applying an ice pack to the outside of the jaw for the first 24 hours limits swelling. Soft foods — yoghurt, dal, soup, mashed vegetables — are recommended for 3–5 days. Avoid smoking, alcohol, hot drinks, and using straws for at least 72 hours: these can dislodge the blood clot that forms in the socket, causing a painful complication called dry socket. Most patients resume their normal routine within 3–7 days. Complete bony healing of the socket takes 4–6 weeks, though you won't notice this during daily life.
When Removal is Not Necessary
Not all wisdom teeth need to be extracted. If all four wisdom teeth have emerged fully, are in correct alignment, can be cleaned properly, and are not causing any issues, they can remain. However, if X-rays show a problematic angle, insufficient space, risk to the adjacent molar, or a history of repeated infections, early removal — ideally in the late teens or early twenties when roots are not yet fully formed and bone is more elastic — makes the procedure simpler and recovery significantly faster. Waiting for a problem to escalate typically leads to a more complex extraction. Dr. Anshalika will review your imaging and give you an honest recommendation based on your specific anatomy.
