Wisdom teeth need to be removed when they cause pain, infection, damage to neighbouring teeth or other complications. Not all wisdom teeth require extraction — some emerge fully and cause no issues. However, because they are the last teeth to appear (usually between ages 17 and 25) and the jaw often lacks space for them, problems are common.
At Pure Smiles in Fulham, Dr Ayzaaz Akram (BDS Liverpool 1995, GDC 70996) assesses wisdom teeth using clinical examination and X-rays to determine whether extraction is necessary. Early assessment prevents complications from worsening. Here are the five clearest signs that your wisdom teeth need attention.
Pain or throbbing at the back of your jaw is the most common indicator of a problematic wisdom tooth. This pain can be constant or intermittent, and it often radiates into the jaw joint, ear or temple on the affected side.
Wisdom tooth pain occurs because the tooth is pressing against bone, gum tissue or the adjacent molar as it tries to emerge. If there is insufficient space, the tooth may become impacted — trapped beneath the gum or wedged against the neighbouring tooth at an angle.
Impacted wisdom teeth do not resolve on their own. They are a progressive problem that typically worsens without professional intervention. If you experience persistent pain at the back of your mouth, contact Pure Smiles for an assessment. learn more
When a wisdom tooth partially emerges, it creates a flap of gum tissue over the tooth. This flap traps food particles and bacteria, leading to a condition called pericoronitis — painful inflammation and infection of the gum tissue surrounding the wisdom tooth.
| Symptom | What It Indicates |
|---|---|
| Red, swollen gum tissue behind the back molar | Active inflammation around the wisdom tooth |
| Pain when biting down or chewing | The gum flap is being compressed against the opposing tooth |
| Unpleasant taste or bad breath | Bacterial infection producing pus and sulphur compounds |
| Difficulty opening the mouth fully | Infection spreading to the surrounding jaw muscles |
| Swelling in the cheek, jaw or neck | Advanced infection requiring urgent treatment |
Pericoronitis can occur even when the wisdom tooth is still fully beneath the gum. It is not a minor inconvenience. It is an active infection that can spread to the jaw, neck and throat if left untreated. Repeated episodes of pericoronitis are a strong indication for wisdom tooth extraction. learn more
When a wisdom tooth remains impacted within the jawbone, a fluid-filled sac (cyst) can develop around the crown of the unerupted tooth. These dentigerous cysts grow slowly but can cause significant damage over time.
Cysts can destroy surrounding jawbone, damage the roots of neighbouring teeth and compress nerves. In rare cases, untreated cysts can develop into more serious growths requiring surgical removal of bone and tissue.
Early extraction of a problematic wisdom tooth eliminates the risk of cyst formation and allows any existing cyst to heal. Your dentist at Pure Smiles will identify cysts on X-ray imaging during routine examinations.
Wisdom teeth that are partially erupted or positioned at an angle create tight spaces against the second molars that are extremely difficult to clean. Plaque and food debris accumulate in these gaps, leading to:
If your wisdom teeth are compromising the health of your other teeth, extraction protects the teeth you want to keep. Pure Smiles offers dental fillings and preventive treatments to restore any damage already caused. learn more
Upper wisdom teeth sit close to the maxillary sinuses. As they grow, the developing roots can push against the sinus floor, causing pressure, congestion, headaches and a feeling of fullness in the cheeks.
Sinus-related symptoms from wisdom teeth are not the most common presentation. They are a recognised cause that is often overlooked. If you experience recurring sinus pressure alongside any of the other signs listed above, ask your dentist to assess your upper wisdom teeth with an X-ray.
Wisdom tooth removal at Pure Smiles is a routine procedure performed under local anaesthetic. Sedation is available for anxious patients. Simple extractions — where the tooth has fully emerged — take 20 to 40 minutes. Surgical extractions of impacted teeth may take slightly longer.
Recovery typically involves mild swelling and discomfort for three to five days, managed with over-the-counter painkillers and soft foods. Most patients return to normal activities within a week.

Wisdom teeth are typically assessed from the late teens onwards, but there is no fixed age for removal. Extraction is recommended whenever a wisdom tooth causes symptoms or poses a risk to neighbouring teeth. Younger patients generally recover faster because the bone is softer and the roots are less fully developed.
Yes, wisdom teeth that are fully erupted, properly aligned and easy to clean do not need to be removed. However, impacted or partially erupted wisdom teeth can cause problems without pain initially. Regular dental X-rays at Pure Smiles allow us to monitor wisdom teeth and recommend extraction before complications develop.
The procedure itself is painless under local anaesthetic. After the anaesthetic wears off, you may experience soreness, swelling and mild bruising for three to five days. Over-the-counter painkillers such as ibuprofen are usually sufficient. Dr Akram provides detailed aftercare instructions to ensure a smooth recovery.
