Wisdom Teeth (Third Molars) – What You Need to Know

Wisdom teeth are the final set of molars to develop, usually emerging in your late teens or early 20s. Because there’s often not enough room in the jaw, they frequently become impacted, partially emerge, or cause crowding. Knowing when and why wisdom teeth may need removal helps you make informed decisions about your oral health.

At Dental Perfections, we tailor advice based on individual risks, symptoms, and imaging, so you get the most appropriate care in the right time frame.

Why might wisdom teeth need to be extracted?
Removal is typically recommended when wisdom teeth cause pain, swelling, or infections such as pericoronitis. They can lead to decay of adjacent teeth, cysts, abscesses, or gum disease . An X-ray helps your dentist assess whether the tooth is problematic or safe to monitor. If the tooth is symptom-free and low-risk, it’s often best left in place but watched during routine check-ups.

What does the removal process involve?
Wisdom tooth extraction begins with a local anaesthetic. Your dentist may also offer sedation or general anaesthetic if the tooth is impacted or you're anxious. The surgeon may cut gum, remove bone, and section the tooth for easier extraction. Stitches, usually dissolvable, may be placed. Most patients go home the same day, and the procedure typically lasts under 40 minutes.

What should I expect during recovery and how can I help with healing?
Expect some swelling, discomfort, stiffness, or bruising, usually most noticeable in the first two days and improving after that. You should eat soft foods, take pain relief like paracetamol or ibuprofen, refrain from smoking, and gently rinse with warm salt water to keep the wound clean. Bleeding can be controlled by applying pressure with a clean cloth or swab. Full healing generally occurs within two weeks.

What are the potential complications of wisdom tooth removal?
Complications can include dry socket (when the blood clot dislodges), infection, or nerve injury causing temporary or, rarely, permanent numbness or tingling in your lip, chin, or tongue. When wisdom tooth roots lie close to nerves in the lower jaw, your dentist may recommend a coronectomy, removing only the crown to reduce this risk. These modern approaches help minimise complications.

Can wisdom teeth be monitored instead of removed?
Yes! If wisdom teeth aren’t causing discomfort or pathology, they may be safely monitored during routine dental catch-ups. Watchful waiting helps you avoid unnecessary surgery. However, if problems develop later, extraction may still become necessary.
