When Should Wisdom Teeth Be Removed — and When Can They Stay?

Wisdom teeth have a bad reputation, but the truth is more balanced: some genuinely need to come out, and some can stay for life. Here’s how to tell the difference.

When a wisdom tooth should go

It keeps getting infected. A partially erupted wisdom tooth leaves a flap of gum that traps food and bacteria. If the area has swollen or hurt more than once (dentists call this pericoronitis), it will keep happening — each episode a little worse.

It’s trapping decay. Wisdom teeth are hard to brush. When one starts decaying — or worse, causes decay in the healthy molar in front of it — removal protects the tooth you actually need.

It’s impacted at an angle. A wisdom tooth lying sideways against the next molar will never erupt properly. It can press on the neighbouring root, cause crowding pressure, or form a cyst around itself over time.

It has no partner. A wisdom tooth with no opposing tooth to bite against slowly over-erupts, digging into the gum or cheek opposite.

When it can stay

• It has fully erupted, upright, with room to function
• You can reach it comfortably with a toothbrush
• It has a healthy partner tooth to bite against
• X-rays show no decay, gum pocketing or pressure on neighbours

A wisdom tooth that meets these conditions is just a molar. There is no rule that says wisdom teeth must be removed “preventively” if they’re healthy and cleanable.

What removal is actually like

The tooth is removed under local anaesthesia — you feel pressure, not pain. A fully erupted tooth comes out much like any other extraction; an impacted one is a minor surgical procedure done in the same chair. Most people are back to work or college the next day, with soreness that settles over two to three days. The first 48 hours of aftercare (no forceful rinsing, no straws, no smoking) matter most for smooth healing.

The bottom line

Don’t wait for the third episode of pain to decide. One examination and X-ray tells you which category your wisdom tooth is in — and if it can stay, you’ll hear that from us plainly.
