Make friends with “wisdom people” – and keep your distance from “wisdom teeth”! If you already have one, a dental check-up is a good idea.
Wisdom teeth are the third molars, usually erupting between ages 17 and 25. Because they come in last, there is often not enough space, so they may grow at an angle or remain impacted in the bone.
Possible problems
- Pericoronitis: inflammation of the gum flap over a partially erupted tooth, causing swelling, pain and limited mouth opening.
- Decay of the wisdom tooth and the adjacent second molar.
- Bone loss and gum disease around the second molar.
- Cysts around impacted teeth (less common).
When is removal usually advised?
Recurrent pericoronitis, decay that is hard to treat or clean, damage to neighbouring teeth, cysts, or as part of an orthodontic or prosthetic plan. Wisdom teeth that are upright, functional and easy to clean may be kept and monitored.
Why imaging is needed
Panoramic X-rays or cone beam CT show the tooth's position, root shape and its relation to the inferior alveolar nerve or the maxillary sinus, so the extraction can be planned safely.
Aftercare
- Bite on gauze as instructed and use cold compresses on the first day.
- Eat soft, cool food; avoid vigorous rinsing, spitting, smoking and straws for 24 hours.
- Take medication as prescribed and attend follow-up visits.
- Contact the clinic if bleeding persists, you develop a fever, or pain and swelling increase after 2–3 days.
Note: Treatment indications and outcomes depend on each person's oral condition, general health and home care. This article is for general information only; an in-person examination is needed for individual advice.
