When to Remove Wisdom Teeth
Wisdom teeth — the third molars at the back of each jaw — usually start to appear in the late teens or early twenties. Some come through cleanly and never cause a problem. Others cause pain, infections, or pressure on the neighbouring teeth. The decision to remove a wisdom tooth is not automatic. At Sandgate Family Dental we look at each case on its own merits, and we are happy to monitor wisdom teeth that are settled rather than removing them just because they are there.
If a wisdom tooth is bothering you, or you would like a clear assessment of whether removal is sensible, you can book an appointment online.

Why we are conservative about wisdom-teeth removal
Wisdom teeth that come through fully, line up reasonably with the rest of the bite, and can be kept clean usually do not need to be removed. The aim of assessment is to identify the wisdom teeth that are likely to cause problems and to weigh up the risks and benefits of removing them. We try to avoid "just in case" extractions where there is no clinical reason.
For background on what wisdom teeth are and how they sit in the jaw, see the main wisdom teeth page.

Common reasons we recommend removal
Recurrent pericoronitis (gum infection around the wisdom tooth)
A partially erupted wisdom tooth often has a flap of gum over part of it. Food and bacteria collect under this flap, and the area becomes painful, swollen, and sometimes infected. One isolated episode can sometimes be settled with a clean and antibiotics. Repeated episodes are a strong reason to consider removal.
Decay you cannot reach
Wisdom teeth at the back of the mouth are hard to brush and floss. If decay has developed in the wisdom tooth itself — or worse, on the back of the second molar in front of it — removing the wisdom tooth is often the better long-term move than trying to fill an area that cannot be cleaned reliably.
Damage to the adjacent tooth
An angled wisdom tooth can press against the back of the second molar. Over time this can cause decay, root resorption, or bone loss on the second molar. Catching this on an OPG before serious damage occurs is one of the main reasons we monitor.
Cysts or other pathology
Some impacted wisdom teeth develop a fluid-filled cyst around the crown. These show clearly on imaging and usually mean the tooth and the cyst should be removed.
Orthodontic reasons
If you are planning orthodontic treatment — clear aligners or braces — your orthodontist may flag wisdom teeth that are likely to interfere with the result or with retention. This is assessed alongside the orthodontic plan, not in isolation.
Persistent pain or pressure
An aching or pressured feeling that comes back regularly, or that wakes you up, is worth assessing. Wisdom-tooth pain that is intermittent but recurring is a typical sign that the tooth is not settling.

When leaving wisdom teeth alone is reasonable
Wisdom teeth are often best left if:
In these cases we monitor at routine check-ups and update an OPG every few years to confirm nothing is changing.

Timing — younger jaws versus older jaws
If a wisdom tooth is going to be removed, doing it earlier — typically in the late teens or twenties — is usually simpler than waiting. The roots are not fully formed, the bone is less dense, and recovery tends to be quicker. That said, age alone is not a reason to remove a healthy wisdom tooth. Plenty of people keep their wisdom teeth into adulthood without issue.

Who decides — and where
Many wisdom teeth can be removed at the practice under local anaesthetic. Cases that involve deeply impacted teeth, very close proximity to the lower jaw nerve, or patients who would prefer sedation are usually referred to an oral surgeon. We will be clear about which category your tooth falls into and why.
Appointment
What to expect if removal is recommended
Once an OPG and assessment have been done, we will explain:
You do not need to decide on the day. Most patients take the information away and book the procedure once they have had time to think it through.
Payment
Health funds and payment
Wisdom-teeth removal usually sits under general dental or oral surgery on most policies, with separate item numbers for simple versus surgical extractions. We are HICAPS providers and can claim your eligible rebate on the day. The amount you receive depends on your individual policy, your level of cover, and your annual limits — see our wisdom teeth cover page for general guidance, and your fund can confirm exact rebates before treatment.

Who this may suit
This page is useful if a wisdom tooth has been bothering you, if you have been told you may need them out, or if you simply want a calm, considered opinion on whether removal is sensible for your situation. It is also useful for parents of teenagers who are starting to wonder whether their child’s wisdom teeth will need attention.
FAQs
When to remove FAQs
Should I have all four out at once?
It depends on each tooth. If all four are impacted and likely to cause problems, removing them together is often more efficient. If only one or two need attention, there is no need to remove healthy wisdom teeth alongside them.
Is it true that wisdom teeth always cause crowding of the front teeth?
The current evidence does not support routinely removing wisdom teeth to prevent crowding of the front teeth. Crowding has multiple causes, and removing wisdom teeth on that basis alone is not generally recommended.
What if my wisdom tooth has been sore once but has now settled?
One settled episode is not always a reason to remove the tooth. We would assess it and discuss whether you are likely to have another flare-up. Patients with repeated episodes tend to do better with removal.
Can I keep my wisdom teeth if they are impacted but not painful?
Often, yes — particularly if they are deeply buried, the surrounding bone is healthy, and there is no damage to neighbouring teeth. We monitor with imaging at intervals.
Will removal be done at Sandgate or referred to a specialist?
Many cases are managed at the practice under local anaesthetic. More complex cases, and patients who prefer sedation or a general anaesthetic, are referred to an oral surgeon.
What if I am pregnant?
Elective wisdom-teeth removal is usually deferred during pregnancy. Urgent issues (such as a significant infection) are managed in consultation with your GP or obstetrician. See pregnancy and dental care.
What happens at the consultation?
We take an OPG, examine the area, and talk through whether removal is sensible. There is no obligation to book the procedure on the day.
