When do wisdom teeth come in? Usually between the ages of 17 and 25, although some appear later and some never do. Eruption often comes with a few days of soreness at the back of the jaw that settles on its own. Pain lasting more than a week, swelling or a bad taste suggest inflammation and are a reason to see a dentist.
At what age do wisdom teeth come in?
Wisdom teeth, the third molars, start forming inside the jaw around the age of 9 or 10. Their crowns are complete in the mid-teens, and most people see them start to appear somewhere between 17 and 25. That timing, around the age people traditionally gain “wisdom”, explains their name in English and in Arabic.
The range is wide. Some people notice them at 16, others in their thirties, and a significant number of adults have one or more wisdom teeth that never develop at all. An X-ray, often a panoramic image, shows whether your wisdom teeth exist, how far they have developed and whether they have room to come through.
How do you know a wisdom tooth is coming through?
- A dull ache or pressure behind the last molar, often in waves
- Tender, slightly swollen gum at the very back of the mouth
- A small white edge of tooth visible through the gum
- Mild discomfort when chewing on that side
- Sometimes a feeling of pressure spreading towards the ear or jaw joint
These signs are usually mild. A wisdom tooth that comes through straight and has enough room may cause only a few uncomfortable days.
How long does wisdom tooth eruption pain last?
Normal eruption discomfort typically lasts a few days at a time, then fades. It can return in short episodes over several months, as the tooth moves a little further each time. Eruption can be a slow process, which is why some people feel “the same tooth” on and off for a year or more.
Pain that lasts longer than about a week, becomes stronger, wakes you at night or comes with a swollen gum flap, a bad taste or difficulty opening your mouth is no longer simple eruption. It usually means the gum around the tooth is inflamed. Our article on wisdom tooth pain and inflammation explains the causes and what helps.
What if the wisdom tooth never comes through?
When there is not enough space or the tooth is tilted, it may stay partly or completely inside the bone. This is called an impacted wisdom tooth. Some cause no trouble for life; others lead to repeated infections or decay of the tooth in front. Read our guide to the impacted wisdom tooth to understand the different positions and when removal is advised.
How to stay comfortable while a wisdom tooth erupts
- Keep brushing right to the back, gently, with a soft brush. Clean gum heals and settles faster.
- Rinse with warm salt water after meals during sore days.
- Use an over-the-counter painkiller, following the package dose, if you need one and it is safe for you.
- Prefer soft food and chew on the other side for a few days.
- Book a check-up if the discomfort keeps coming back, so the position of the tooth can be checked on an X-ray.
If removal is needed one day, our complete guide to wisdom tooth removal explains what happens and how recovery goes.

Frequently asked questions
Can wisdom teeth come in after 30?
Yes. Most wisdom teeth appear between 17 and 25, but some erupt later, sometimes in the thirties or even later, especially when they have been slowly moving inside the bone. A tooth that starts causing symptoms late in life should be examined with an X-ray to check its position and the health of the tooth in front of it.
Is it normal to have fewer than four wisdom teeth?
Yes. It is common to be missing one or more wisdom teeth, and some people have none at all. This is a normal variation and not a problem in itself. An X-ray is the only way to know for sure whether a wisdom tooth is absent or simply hidden inside the bone.
Can an erupting wisdom tooth cause a headache?
It can. Pressure and inflammation at the back of the jaw can be felt in the temple, the ear or the side of the head. A mild, short-lived headache during eruption is not unusual. A strong or persistent headache, fever or facial swelling needs examination rather than simple painkillers.
Should I have my wisdom teeth removed before they come in?
Not automatically. Healthy wisdom teeth with enough room can be kept. Early removal is sometimes recommended when an X-ray shows that a tooth clearly has no room and is likely to cause problems, because removal is usually easier in younger adults. The decision is made case by case after an examination.
Why does my wisdom tooth hurt only sometimes?
Eruption happens in small steps, so the discomfort tends to come in episodes. Pain can also flare up when food and bacteria collect under the gum covering a partly erupted tooth, then settle again after cleaning. If episodes keep returning, it is worth having the tooth examined.
