Not everyone has wisdom teeth. Most adults develop up to 4 third molars, but some people have fewer, impacted teeth, or none at all due to genetics and jaw development.
Wisdom teeth are the last set of molars to develop and often raise questions about whether they are necessary, whether they need removal, and why some people never get them.
What Are Wisdom Teeth?
Wisdom teeth are the third molars located at the back of the mouth. They usually develop between the ages of 17 and 25, although timing varies between individuals.
These teeth were once useful for early humans who needed extra chewing power for coarse foods. Modern diets and smaller jaw sizes mean there is often less space for them to emerge properly.
Does Everyone Have Wisdom Teeth?
No, not everyone has wisdom teeth. There are 3 scenarios when it comes to wisdom tooth development:
- All 4 wisdom teeth develop
- Fewer than 4 wisdom teeth develop
- No wisdom teeth develop at all
Research shows that up to 35% of people may be missing one or more wisdom teeth, meaning it is completely normal not to have a full set.
In some cases, wisdom teeth never form because the tooth buds do not develop. In others, the teeth exist but remain hidden beneath the gums or bone.
Why Some People Don’t Have Wisdom Teeth
Missing wisdom teeth are mainly linked to genetics and jaw development.
People with smaller jaws often lack the space needed for third molars to form or erupt. Over generations, this has led to an increase in people who naturally develop fewer wisdom teeth or none at all.
In simple terms, if the body does not “need” the extra teeth, they may not develop.
Do Wisdom Teeth Always Come Through?
No, wisdom teeth do not always erupt fully. They can develop in 3 different ways:
- Fully erupted – the tooth comes through the gums and functions normally
- Partially erupted – the tooth breaks through the gums but remains partly covered
- Impacted – the tooth stays trapped under the gum or bone
Impacted or partially erupted wisdom teeth are more likely to cause problems such as infection, swelling, or pain.

Does Everyone Have to Get Rid of Their Wisdom Teeth?
No, wisdom teeth only need to be removed when they cause problems.
Healthy wisdom teeth that are fully erupted, aligned, and easy to clean can remain in place without issue.
When removal is needed
- Pain or ongoing discomfort
- Infection or swelling around the gums
- Difficulty cleaning the area
- Tooth decay or gum disease
- Pressure affecting nearby teeth
When removal is not needed
- Teeth are fully erupted and functional
- No signs of infection or decay
- Easy to clean and maintain
The decision is based on your individual situation, not a one-size-fits-all approach.
When Wisdom Teeth Become a Problem
Problematic wisdom teeth often present with clear symptoms.
Common signs include:
- Swelling at the back of the mouth
- Jaw pain or stiffness
- Difficulty opening the mouth
- Food getting trapped behind the tooth
- Bad taste or bad breath
These symptoms often indicate infection or inflammation around a partially erupted tooth.
Early assessment prevents the issue from worsening and reduces the need for more complex treatment.
How Dentists Assess Wisdom Teeth
Wisdom teeth are assessed using a clinical examination and dental X-rays.
This allows the dentist to evaluate:
- Tooth position and angle
- Available space in the jaw
- Whether the tooth is impacted
- Risk of infection or damage to nearby teeth
This assessment provides a clear basis for deciding whether monitoring or removal is the best option.
What Happens If Removal Is Needed
Wisdom tooth removal is a common dental procedure used to prevent or treat infection and crowding.
The process involves:
- Numbing the area for comfort
- Removing the tooth safely
- Providing aftercare instructions to support healing
Recovery varies, but most patients who have a smooth recovery return to normal activities within a few days to a week.

When to See a Dentist About Wisdom Teeth
You should book an appointment if you notice:
- Pain lasting more than 48 hours
- Swelling around the gums or jaw
- Difficulty chewing or opening your mouth
- Signs of infection, such as bad taste or odour
Early assessment helps identify whether your wisdom teeth are developing normally or require treatment.
