Wisdom Teeth: When They Need to Come Out and When They Don’t

By Lovik Mirzaeian, DDS. Updated September 2026.

Wisdom teeth need removing when they are impacted, repeatedly infected, decaying, or damaging the tooth in front. If they have come through fully, sit in your bite normally and you can brush them, there is no reason to take them out.

Routine removal of every wisdom tooth is no longer the default position, and a dentist recommending removal should be able to say specifically why for your teeth. Here is what actually decides it.

Why They Cause Trouble

Wisdom teeth are the last molars to arrive, usually between seventeen and twenty five. By then the rest of the jaw is fully developed, and in many people there is simply not enough room left at the back.

A tooth without room does one of several things. It stays buried in bone. It comes through partly, leaving a flap of gum over it. It grows at an angle and pushes into the molar in front. Each of those creates a different problem.

When Removal Is the Right Call

Repeated Infection Under a Gum Flap

A partly erupted wisdom tooth leaves a pocket of gum that traps food and bacteria and cannot be cleaned. The result is pericoronitis, a painful swelling that recurs. Once it has happened more than once it will keep happening.

Decay You Cannot Reach

Wisdom teeth sit far back and are hard to brush well. Decay there is common and often not restorable, because access for a filling is poor. Worse, the decay frequently spreads to the healthy molar in front of it.

Damage to the Second Molar

A wisdom tooth angled forward presses against the root of the tooth in front, and can resorb it. This is the strongest reason to remove an asymptomatic impacted tooth, because losing the second molar is a much bigger problem than losing the wisdom tooth.

Cysts

A tooth sealed in bone can develop a fluid-filled cyst around the crown, which slowly destroys surrounding bone. Uncommon, but it is silent, and it is one reason impacted teeth get monitored with x-rays rather than ignored.

Gum Disease Behind the Second Molar

The pocket behind a partly erupted wisdom tooth is impossible to keep clean and drives bone loss on the neighbouring tooth.

When to Leave Them Alone

Fully erupted, in a normal bite, cleanable and causing nothing. Completely buried in bone with no cyst, no pressure on the next tooth, and stable on x-rays over years. Cases where the risk of the surgery, particularly nerve proximity in an older patient, outweighs a theoretical future problem.

Monitoring is a legitimate plan. It just means periodic x-rays rather than doing nothing. The American Dental Association supports the same case by case approach.

What the Procedure Involves

A fully erupted wisdom tooth comes out much like any other tooth, often in minutes. An impacted one requires an incision in the gum, sometimes removing a small amount of bone, and often sectioning the tooth to remove it in pieces. That sounds worse than it feels, because the area is completely numb throughout.

Sedation is available for anyone who would rather not be present for it, and for anxious patients it turns the whole thing into a non-event.

Afterwards: no rinsing for the first day, no straws, no smoking, and no poking at the site, all of which risk dislodging the clot and causing a dry socket. Ice for the first day, then warmth. Soft food. Pain that improves for two days then sharply worsens is the classic dry socket pattern and it is easily treated, so call.

What the First Week Actually Looks Like

Day one is the numb day. Eat once sensation returns, keep to cool soft food, and use ice on the outside of the face in twenty minute stretches. Do not rinse at all for the first twenty four hours.

Day two and three bring the most swelling, and this is normal rather than a sign anything is wrong. Start gentle warm salt water rinses after the first day. Keep your head slightly raised at night, which reduces the morning puffiness.

By day four most people are eating fairly normally and the swelling is going down. Bruising that appears on the cheek or jaw at this point is common and settles on its own.

By the end of the first week the discomfort should be background rather than a problem. What is not normal is pain that improves and then gets sharply worse around day three or four, often with a bad taste and an empty looking socket. That is a dry socket, it is not dangerous, and it is settled quickly with a dressing, so it is worth a call rather than a week of misery.

Frequently Asked Questions

Do wisdom teeth always need to be removed?

No. If they come through fully, sit in a normal bite, and you can clean them properly, there is no reason to remove them. Removal is for teeth that are impacted, causing crowding pressure, repeatedly infected, decaying, or damaging the tooth in front of them.

What age is best to have wisdom teeth out?

Late teens to early twenties, when the roots are not yet fully formed and the bone is less dense. Recovery is faster and complications are less common at that age. After thirty the roots are longer and closer to the nerve, which makes the procedure more involved.

How long does recovery take?

Most people are comfortable within three to four days and back to normal within a week. Swelling peaks around day two or three. A simple extraction of a fully erupted wisdom tooth is often a two day recovery, an impacted one buried in bone takes longer.

Is wisdom tooth removal painful?

The procedure itself is not, the area is fully numb and sedation is available if you want it. The recovery involves soreness and swelling for a few days, managed well with ordinary painkillers for most people. Pain that gets worse around day three or four can mean a dry socket, which is worth calling about.
