Wisdom teeth: what they are and how removal works in NZ
Health NZ says wisdom teeth are the last four teeth to come in, at around 18 to 20, and can become impacted if the jaw does not have room. Removal is sometimes done under local anaesthetic in a dental clinic; complicated cases can be done in hospital or a clinic under sedation or general anaesthetic. Complications are listed too.

What are wisdom teeth and when do they come in?
Health NZ’s wording:
“Most people have 32 teeth by the time they are 18. At around age 18 to 20 the third molars (wisdom teeth) are the last 4 teeth to come in.”
“Most problems with wisdom teeth develop between the ages of 15 and 25.”
Why do wisdom teeth become impacted?
“Your jaw may not be large enough to fit them and they may become impacted. This means they cannot break through your gums.”
“If your wisdom teeth are aligned properly, have come through completely, and you can reach them to clean them, they will probably not have to come out.”
Who removes wisdom teeth: a dentist or an oral surgeon?
Health NZ’s wisdom-teeth page refers to:
“You will probably need a general anaesthetic (where you are asleep for the procedure) or lighter 'conscious sedation' for this. Your oral and maxillofacial surgeon or dentist will let you know which is best for you.”
The page does not say which teeth a dentist removes and which an oral surgeon removes. The Dental Council of New Zealand defines two separate surgical scopes of practice:
“Oral and maxillofacial surgery specialists practise in the branch of dentistry in that part of surgery which deals with the diagnosis, surgical and adjunctive treatment of diseases, injuries and defects of the human jaws and associated structures.”
“Oral surgery specialists practise in the branch of dentistry concerned with the diagnosis and surgical management of conditions affecting the oral and dento-alveolar tissues.”

Where is wisdom tooth removal done?
Health NZ says a wisdom tooth that has fully come through the gum is removed like any other tooth. For one under the gum it says:
“A wisdom tooth that has fully come through your gum can be taken out the same way as any other tooth.”
“Sometimes this can be done with a local anaesthetic in your local dental clinic. More complicated wisdom teeth can be removed in hospital or a dental clinic.”
Will I need sedation or a general anaesthetic for wisdom tooth removal?
Health NZ says this about the more complicated wisdom teeth:
“You will probably need a general anaesthetic (where you are asleep for the procedure) or lighter 'conscious sedation' for this. Your oral and maxillofacial surgeon or dentist will let you know which is best for you.”
What pain relief is used after wisdom tooth removal?
Health NZ’s self-care list says:
“Take the pain relief prescribed by your oral surgeon or dentist for the first 48 hours.”
This guide names no drug and gives no dose.
What complications can follow wisdom tooth removal?
Health NZ lists complications after removal. Some of its statements:
“You may have some complications after your wisdom teeth are removed.”
“If you have heavy bleeding that will not stop, contact your dentist or oral surgeon.”
“Dry socket is common.”
“Very rarely, it may be permanent.”
Which Tauranga clinics state wisdom teeth or oral surgery on their own website?
16 of the 32 listed clinics with a single-clinic website state wisdom teeth or oral surgery on their own website (data checked 2026-09-30). Clinics on multi-branch group sites are not attributed by branch.
| Area | Listed clinics | State the service | Site not read |
|---|---|---|---|
| Tauranga | 24 | 5 | 10 |
| Bethlehem, Greerton and Pyes Pa | 11 | 4 | 4 |
| Mount Maunganui (small sample) | 8 | 1 | 4 |
| Papamoa | 10 | 5 | 4 |
| Te Puke (small sample) | 3 | 0 | 3 |
| Katikati, Omokoroa and Te Puna (small sample) | 4 | 1 | 3 |
A clinic counts as stating the service only when its own single-clinic website says so. A clinic on a group website, or without a website, is counted as unread. Unread is not a statement that the clinic declines the service.
Questions to put to a clinic before a wisdom tooth consultation:
- Which practitioner would remove the tooth, and under which scope of practice?
- Has the tooth come fully through the gum, or is it under it?
- Which complications should be watched for after removal, and who should be called?
