Do all wisdom teeth need to be removed?
No. A healthy wisdom tooth that is well positioned and can be cleaned may remain in place. An impacted tooth also needs individual assessment. Being pain-free does not necessarily mean there is no disease, so an examination and suitable imaging may be needed.
Wisdom teeth are the third molars. They often emerge in late adolescence or early adulthood, but development varies. A tooth that cannot be seen may be unerupted or absent; looking at the gum alone cannot establish which.
When might extraction be recommended?
Reasons for assessment include decay that cannot be restored, recurring inflammation around the tooth, damage to the adjacent second molar or certain changes in the bone. Removal can also form part of a wider surgical plan.
The idea that a wisdom tooth will inevitably push other teeth out of line is not a substitute for diagnosis. Routine preventive removal of every healthy impacted tooth is not a universal recommendation. NICE guidance on wisdom teeth discusses the role of established disease; your clinician weighs the benefits and risks for your situation.
If removal is not indicated, agree how the tooth will be monitored, how to clean it and which symptoms should prompt an earlier review.
Pain, swelling and difficulty opening the mouth
Pain at the back of the mouth can arise from inflamed tissues around a partly erupted tooth, decay or a neighbouring tooth. Fever, increasing swelling or restricted mouth opening should not be dismissed as normal eruption. Seek urgent dental advice.
Difficulty breathing or swallowing, or swelling spreading to the neck, needs immediate medical help. In Poland, call 112. Our toothache guide gives further information about urgent symptoms.
What happens during removal?
- Assessment and planning. The clinician reviews your health, medicines and relevant images, and explains the tooth’s position and procedure-specific risks.
- Anaesthetic. Local anaesthetic is commonly used. You may feel pressure or movement; tell the clinician if you feel pain.
- Extraction. Depending on the position, the procedure may involve opening the gum, dividing the tooth or removing some bone.
- Wound care. Bleeding is checked, stitches are placed if needed, and you receive instructions and a review plan.
The duration depends on anatomy and the procedure. It cannot be predicted reliably just by whether the tooth is upper or lower.
Looking after the extraction site
Follow the instructions given for your procedure. During the first day, avoid vigorous rinsing or disturbing the socket. Clean the other teeth gently and choose soft food at a suitable temperature. While numb, take care not to bite the lip or cheek.
Smoking interferes with healing, so discuss the period of avoiding it with your clinician. Use medicines as advised, not leftovers from an earlier treatment. See the NHS guide to wisdom tooth removal and our aftercare information.
When should you contact the clinic afterwards?
Some pain, swelling and restricted opening can occur, but the pattern matters. Increasing pain after initial improvement, fever, continuing bleeding or another worrying change needs assessment. Dry socket is one possible cause of significant pain, but it cannot be diagnosed from a description alone.
Altered sensation is another possible complication, particularly when lower wisdom-tooth roots are close to a nerve. Report numbness that persists beyond the expected anaesthetic period. For oral surgery at ProDent, bring existing images to the consultation so the clinician can decide what further assessment is required.
