Impacted Wisdom Tooth

A wisdom tooth can stay trapped in gum or bone and may cause gum pain, swelling, bad breath, or a bad taste.

[1][2]

The short answer

An impacted wisdom tooth is one that remains partly or completely trapped because gum, bone, or another tooth blocks its route.

What are the signs of an impacted wisdom tooth?

An impacted wisdom tooth may cause no symptoms. When it does cause trouble, a person may notice pain at the back of the mouth, swelling or tenderness around the gum, difficulty opening the mouth, bad taste or breath, or pressure near nearby teeth.

What is assessed?An impacted wisdom tooth may cause no symptoms. When it does cause trouble, a person may notice pain at the back of the mouth, swelling or tenderness around the gum, difficulty opening the mouth, bad taste or breath, or pressure near nearby teeth.[1][2]
What guides the next step?Bad breath, a bad taste, swollen gums, jaw pain, difficulty opening the mouth, or a visible gap can occur when the tooth is partly erupted.[1][2]

[1][2]

Why does a wisdom tooth become impacted?

Impaction can occur when there is not enough room for the tooth, the tooth is angled, or another tooth or bone blocks its route. The position of the tooth and the surrounding structures determine what happens next.

[1][2]

Is the wisdom tooth partly or fully impacted?

A wisdom tooth may be partly visible, fully covered by gum, or held within bone. The important distinction is whether it is cleanable and symptom-free, or whether its position is linked with pain, infection or damage around it.

What guides the next step?A tooth can be partly erupted, completely covered by gum, or held in bone; food and plaque can collect around a partly erupted tooth.[1][2]

[1][2]

Which wisdom-tooth problems need attention?

Risk depends on the tooth position, the room available for eruption, and whether food and plaque can collect around a partly erupted tooth. A clinical examination is needed to judge an individual tooth.

[1][2]

How is an impacted wisdom tooth found?

A dentist examines the back of the mouth and uses dental imaging to see the tooth position, its relationship with nearby teeth and the surrounding bone. That information guides the treatment discussion.

[1][2]

When is an impacted wisdom tooth removed?

A symptom-free tooth may be monitored when examination supports that approach. A tooth causing repeated symptoms or local problems may need removal. The choice depends on the clinical and imaging findings.

What guides the next step?Removal is the usual treatment for an impacted wisdom tooth, while a tooth causing no problems may need no treatment.[1][2]

[1][2]

What shapes the cost of wisdom-tooth treatment?

The cost is shaped by the examination, dental imaging, and whether removal is needed; an infected tooth may also require antibiotics before extraction.

[1][2]

What problems can an impacted wisdom tooth cause?

An impacted tooth can be associated with pain, infection, decay, or damage involving nearby structures. Dental examination and imaging show which of these problems is present.

[1][2]

Can wisdom-tooth impaction be avoided?

A blocked wisdom tooth cannot be made to erupt correctly with a home method; earlier assessment may be useful because removal before age 20 often heals more easily.

Frequently asked questions

What should I do first?

A dentist examines the back of the mouth and uses dental imaging to see the tooth position, its relationship with nearby teeth and the surrounding bone. That information guides the treatment discussion.
