In short
Wisdom teeth are the last teeth to come in, usually in the late teens or twenties. They are removed if they cause pain, infection, crowding or damage to nearby teeth. Your dentist will take X-rays and explain whether removal is needed.
What are wisdom teeth?
Wisdom teeth are the third molars at the back of the mouth. Some people have all four, some have fewer and some never have them. They may come in normally, partly or stay under the gum.
When is removal recommended?
Removal may be recommended if a wisdom tooth is impacted (stuck under the gum or against another tooth), partly through the gum and getting infected, damaging the tooth next to it, decayed or hard to clean, or linked to cysts or other problems. A tooth that is healthy and not causing problems may not need to be removed.
What happens during removal?
- Exam and X-rays. The dentist checks the position of the teeth and roots.
- Planning. You discuss anaesthetic and sedation options and how complex the removal is.
- Removal. The area is numbed. Some teeth come out simply. Others need the gum opened or the tooth sectioned.
- Aftercare. You receive written instructions.
Sedation options
If you feel anxious, ask your dentist about sedation. Read our guide to sedation dentistry and ask the clinic which options are available.
Recovery and aftercare
Swelling, tenderness and some bleeding are common for the first few days. Your dentist may advise rest, cold packs, soft foods and gentle rinsing after the first day. Avoid smoking and drinking through a straw, because these can disturb the blood clot. Dry socket happens when the clot is lost, and causes increasing pain a few days after removal. Call the clinic if you think you have it, or if you have a fever, heavy bleeding or swelling that gets worse.
What affects the cost?
The cost depends on how many teeth are removed, how deeply they sit and the sedation used. Your dentist can give you a plan after an exam. Ask the clinic about insurance and payment options.
