Wisdom teeth usually emerge between ages 17 and 25; when space is limited they may partially erupt or remain impacted. Impaction alone does not mean that a tooth must be removed.
This content is general information, not a personal diagnosis or treatment recommendation. A dental examination is needed for individual symptoms.
Rapidly increasing facial or jaw swelling, fever, difficulty swallowing or breathing, marked difficulty opening the mouth, bleeding that will not stop, or worsening pain despite pain relief requires urgent assessment.
Must wisdom teeth always be removed?
No. NICE guidance does not recommend routine prophylactic removal of pathology-free impacted wisdom teeth. Position, cleanability, effects on the neighbouring tooth, existing disease and surgical risks should be considered together.
When may removal be considered?
The decision should be based on clinical examination and imaging.
- Repeated or severe pericoronitis
- Unrestorable decay or pulpal or periapical disease
- Decay, root resorption or periodontal damage affecting the neighbouring tooth
- Abscess, cellulitis or another spreading infection
- A cyst, tumour or other pathology around the tooth
- A requirement connected with planned jaw or reconstructive surgery
What symptoms can indicate a problem?
Pain or tenderness at the back of the jaw, red or swollen gum, pain on chewing, a bad taste or breath, difficulty opening the mouth, cheek swelling and repeated infection can indicate a problem. Lack of pain does not guarantee absence of disease.
Can a painless impacted tooth be monitored?
A tooth without pain, infection, decay, a cyst or damage to a neighbouring tooth may be monitored. Its angle, root development, relationship to the nerve and the person’s ability to attend follow-up all inform that decision.
Examination and imaging
The dentist examines the tooth, surrounding gum and neighbouring teeth. A panoramic X-ray can show eruption direction, depth, root shape, relationship to the lower-jaw nerve and nearby tissues. Three-dimensional imaging may be needed when close nerve contact is suspected.
How is a wisdom tooth removed?
A fully erupted tooth may be removed with a simple extraction. A tooth beneath gum or bone may require surgery under local anaesthetic, sometimes involving a small incision, controlled bone removal, sectioning of the tooth and stitches. Difficulty depends on position, roots and nerve relationship.
Aftercare
Protecting the blood clot supports healing, and your clinician’s personal instructions take priority.
- Do not rinse forcefully in the first hours
- Bite on gauze for the advised time
- Avoid very hot, hard or granular foods on the first day
- Do not disturb the area with your tongue or fingers
- Do not smoke
- Use medicines only as directed
- Continue oral hygiene without traumatising the socket
Possible complications
Dry socket, infection, bleeding and temporary or, rarely, persistent altered sensation from nearby nerves can occur. Contact your clinic for increasing pain or swelling, fever, a bad taste, pus or bleeding that does not stop.
Common questions
Mild eruption tenderness may settle, but repeated pain or pain with swelling needs assessment. More than one wisdom tooth can sometimes be removed in one visit depending on health, position and complexity. Difficulty varies with tooth angle, depth, root shape and nerve proximity.
Assessment at Ersa Dental
The aim is not to remove every impacted tooth, but to identify teeth likely to cause harm and monitor those that can remain healthy. A final decision requires clinical examination and appropriate imaging.
