Wisdom teeth are the last adult molars to appear, usually in late teens or early adulthood. If you are wondering when do wisdom teeth come through, the usual answer is from the late teenage years into the mid-20s. The Australian Dental Association says wisdom teeth generally appear around 18 to 25 years; Experts at Westpoint Dental notes they often start erupting around age 17.
What age do wisdom teeth usually come through?
Wisdom teeth, also called third molars, sit at the very back of the mouth. Many people expect four, one in each corner, but not everyone develops all four. Some people have fewer, and some have none.
A typical wisdom teeth age range is 17 to 25, but timing varies. A teenager may feel early pressure at the back of the jaw. A person in their late 20s may only discover wisdom teeth on a dental X-ray. Age alone does not show whether the teeth are healthy, impacted, or likely to cause trouble.
Why do wisdom teeth come through later?
Most adult teeth come through during childhood. Wisdom teeth develop later and try to erupt when the jaw has already reached its adult size. If there is limited room, a wisdom tooth may push against the tooth in front, grow at an angle, stay trapped under the gum, or only partly break through. This is why wisdom teeth can be quiet for years and then suddenly cause pain, swelling, or pressure.
Signs your wisdom teeth are coming through
Some wisdom teeth appear without much discomfort. Others cause a dull ache or tight feeling at the back of the mouth.
Common signs include:
- Tenderness behind the back molars
- Swollen or red gum tissue
- Pressure in the jaw
- Discomfort when chewing
- A gum flap over part of the tooth
- Food getting caught around the area
- Bad breath or an unpleasant taste
Mild pressure can happen as a tooth erupts. Pain that keeps returning, spreading swelling, fever, pus, or trouble opening the mouth may point to infection or impaction. Inflamed gum, facial swelling, pus, swollen glands, fever, bad breath, and difficulty opening the mouth are possible signs of wisdom tooth infection.
Do wisdom teeth always come through properly?
No. A wisdom tooth can erupt fully, partly erupt, or remain hidden under the gum. A partially erupted wisdom tooth can create a small pocket where food and bacteria collect. Even careful brushing may not reach the area well.
An impacted wisdom tooth does not come through in a normal position. It may sit sideways, lean into the neighbouring molar, or remain covered by bone or gum. This can lead to repeated gum soreness, food trapping, decay in a hard-to-clean spot, pressure on the second molar, cheek biting, jaw stiffness, or recurring infection.
A dentist can check whether the tooth is still erupting normally or whether it is stuck. An X-ray can show the angle of the tooth, root position, and how close it sits to nearby structures.
When should you see a dentist?
Book a dental check if you have pain at the back of your mouth, swollen gums, jaw stiffness, bad taste, or a wisdom tooth that has only partly come through. It is also wise to ask about wisdom teeth during a routine visit if you are in your late teens or early 20s.
At Westpoint Dental Clinic in Blacktown, a dentist can assess the area, discuss symptoms, and advise whether monitoring, treatment, or removal may be suitable. If a tooth is impacted or repeatedly infected, wisdom teeth removal in Blacktown may be discussed as part of your options.

Some wisdom teeth can be removed under local anaesthetic, while more severe cases may need general anaesthetic in hospital. The right approach depends on the tooth’s position, symptoms, medical history, and comfort level. If a wisdom tooth is healthy, fully erupted, easy to clean, and not harming nearby teeth, your dentist may simply monitor it.

Frequently Asked Questions:
What age do wisdom teeth come through?
Wisdom teeth commonly come through between 17 and 25. Some appear earlier or later, and some never fully erupt. A dental X-ray can confirm whether they are present and how they are positioned.
Can wisdom teeth come through at 16 or 17?
Yes. Wisdom teeth can begin erupting around 17, and some people notice symptoms slightly earlier. Early pain or swelling should still be checked, especially if the gum looks inflamed.
Can wisdom teeth come through after 25?
Yes. Some wisdom teeth appear after 25, while others stay under the gum. Late symptoms can occur if a tooth shifts, becomes infected, or is difficult to clean.
How do I know if my wisdom tooth is impacted?
Possible signs include pain, swelling, jaw stiffness, bad taste, gum flaps, or pressure on nearby teeth. Some impacted teeth cause no symptoms, so X-rays are often needed.
Do all wisdom teeth need to be removed?
No. Wisdom teeth only need removal when they cause problems or are likely to. Your dentist will consider symptoms, position, cleaning access, and risk to nearby teeth.
