Wisdom Teeth

Also called: wisdom teeth, wisdom tooth, impacted tooth

Wisdom teeth are the last adult teeth to develop, usually appearing at the back of the mouth during the late teens or early adulthood. While some emerge normally and cause no problems, others can become impacted, partially erupted or difficult to clean, sometimes leading to pain,

Why it happens?

Wisdom teeth, also known as third molars, are the final set of permanent molar teeth and usually begin to emerge later than the rest of the adult teeth. Some people develop all four, while others have fewer or no wisdom teeth at all. When there is sufficient space within the jaw, a wisdom tooth may erupt normally and function like any other molar. Problems are more likely when there is not enough room for the tooth to emerge into a healthy, functional position.

A wisdom tooth that cannot fully emerge is described as impacted. It may remain completely beneath the gum or emerge only partially, and it can be positioned vertically, horizontally or at an angle towards the neighbouring tooth. A partially erupted wisdom tooth can create an area around the gum where food and bacteria become trapped. This may lead to inflammation or infection around the tooth, known as pericoronitis, causing pain, swelling, an unpleasant taste or difficulty opening the mouth.

The position of wisdom teeth can also make effective brushing and interdental cleaning difficult. As a result, decay or gum problems can develop around the wisdom tooth or the neighbouring second molar. Cysts and other complications are possible but less common. Importantly, wisdom teeth do not automatically need to be removed simply because they are present or impacted. Many remain symptom-free and can be monitored, while treatment is generally considered when there is evidence of disease, repeated symptoms or another clear clinical reason.

How far along is it?

Early

The wisdom tooth is developing or beginning to emerge through the gum. There may be temporary pressure or mild tenderness, although many people experience no symptoms.

Moderate

The tooth has insufficient space to erupt normally or remains partly covered by gum. Food and bacteria may become trapped, increasing the likelihood of discomfort, inflammation or decay.

Advanced

Repeated infection, persistent pain, significant decay, gum problems or damage to nearby structures may develop, making professional assessment and possible removal necessary.

What addresses it?

Treatments that address this

Wisdom teeth removal→Oral & maxillofacial surgery→

Wisdom teeth that are healthy, fully erupted and causing no problems may not require treatment. A dental assessment is worthwhile if you develop recurring pain or tenderness at the back of the mouth, swollen gums, difficulty cleaning around a wisdom tooth or repeated episodes of inflammation.

Seek prompt dental attention if you experience significant swelling, severe or worsening pain, pus or an unpleasant taste, fever, or increasing difficulty opening your mouth or swallowing. These symptoms may indicate an infection that requires professional assessment.

Quick Questions:

Does everyone get wisdom teeth?

No. Some people develop all four wisdom teeth, while others develop only one, two or three, and some do not develop them at all. This is a normal variation.

Why do wisdom teeth become impacted?

Impaction commonly occurs when there is insufficient space within the jaw for a wisdom tooth to erupt normally. The tooth may remain beneath the gum or emerge at an angle or only partially.

Do impacted wisdom teeth always need to be removed?

No. An impacted wisdom tooth that is healthy and causing no disease may simply be monitored. Removal is generally considered when there are problems such as repeated infection, decay, disease or damage to neighbouring structures.

What does wisdom tooth pain feel like?

Symptoms can include tenderness or aching at the back of the jaw, swollen or painful gums, discomfort when chewing and difficulty opening the mouth. Persistent or severe pain should be assessed by a dental professional.
