Repeated gum swelling
Tender or swollen gum behind the last tooth, a bad taste or difficulty opening may indicate inflammation or infection.
Wisdom teeth removal is considered when a third molar is causing, or is likely to cause, problems such as repeated infection, decay, damage, pain or difficulty with cleaning.
Not every wisdom tooth needs to be removed. The decision depends on symptoms, position, cleaning access, nearby teeth and the risks of leaving the tooth compared with treatment.

When a wisdom tooth does not erupt into a cleanable position, the surrounding gum may become inflamed or infected. The tooth or the tooth in front can also develop decay. Assessment helps determine whether monitoring, local care, removal or referral is appropriate.
Tender or swollen gum behind the last tooth, a bad taste or difficulty opening may indicate inflammation or infection.
Pain can have several causes, so an examination is needed before attributing it to wisdom teeth.
A partly erupted or awkwardly positioned tooth can be hard to brush and may affect the neighbouring tooth.
A wisdom tooth may be assessed because of its position, nearby structures or a change seen on imaging.
Treatment recommendations depend on the findings, your health history and your preferences.
Review symptoms, medical history, mouth opening, gum condition and the visible part of the tooth.
Use suitable X-rays to assess position, roots and nearby anatomy before recommending treatment.
Discuss the treatment setting, expected recovery and any referral requirements. The treating clinician will confirm anaesthetic arrangements.
| Approach | When it may be discussed | Consideration |
|---|---|---|
| Monitor | No disease or concerning change | Requires review and good cleaning access |
| Local preventive care | Early gum inflammation or food trapping | May not solve an ongoing position problem |
| Removal | Repeated infection, decay, damage or other indication | Involves surgical risks and recovery |
| Specialist referral | Complex position, anatomy or health considerations | Care is coordinated with an oral surgeon or specialist |
This page provides general information. A dentist needs to assess your mouth before recommending treatment. Risks, benefits, alternatives and likely costs vary.
No. A healthy wisdom tooth that is functional, cleanable and not harming nearby structures may be monitored. Removal should be recommended for a clinical reason.
Assessment usually includes symptoms, examination and suitable X-rays to review tooth position, roots, nearby teeth and relevant anatomy.
Local anaesthetic is used to numb the area during treatment. Some swelling and discomfort are expected afterwards; the team will explain appropriate aftercare and pain management.
Recovery varies with the number and complexity of teeth removed and individual healing. Your dentist will provide instructions and explain when to seek review.
Ask the treating provider what assistance or transport you will need after the planned treatment. Follow their specific instructions before arranging to drive.
Seek prompt care for increasing swelling, fever, difficulty swallowing, restricted breathing or severe symptoms. Breathing difficulty or major swelling requires emergency medical attention.
Arrange an assessment to discuss the concern, available options and likely fees.
