Your wisdom teeth are starting to push through and suddenly everyone has advice: your friends had theirs out at seventeen, your mum says it’s just what people do. But not everyone actually needs wisdom teeth removal — and in Bayswater, the decision is based on individual assessment, not a blanket rule.

Here’s a straightforward look at what wisdom teeth are, what actually causes problems, and how a dentist decides whether yours need to come out.

What Are Wisdom Teeth?

Wisdom teeth are your third molars — the last four teeth to develop, usually appearing between the ages of 17 and 25.

Humans evolved with wisdom teeth when diets were rougher and teeth wore down faster, leaving room for a third set of molars. Modern diets and better dental hygiene mean most people’s teeth last longer — and modern jaws tend to be slightly smaller. The result is that wisdom teeth often arrive in a mouth that doesn’t have enough room.

That said, some people have no problems with their wisdom teeth at all. They come through cleanly, fit well, and cause no issues for decades.

Does Everyone Need Their Wisdom Teeth Removed?

Honestly, one of the biggest myths is that everyone needs their wisdom teeth removed. That’s not true.

If your wisdom teeth have erupted fully, are easy to clean, aren’t causing pain, and aren’t damaging the teeth beside them, there may be no reason to remove them. Regular monitoring with periodic dental X-rays is often all that’s required.

The decision isn’t based on age alone — it’s based on how your wisdom teeth are developing, whether they’re causing issues, and what your individual mouth structure looks like. Some patients keep their wisdom teeth for life without any problems.

Signs Your Wisdom Teeth May Need Removal

Certain symptoms suggest your wisdom teeth are worth getting checked sooner rather than later:

• Pain or pressure at the back of the mouth, particularly when eating
• Swelling or redness in the gum around the wisdom tooth
• Repeated infections (a condition called pericoronitis — where the gum flap over a partially erupted tooth becomes inflamed)
• Difficulty opening your mouth fully
• Food trapping between the wisdom tooth and the tooth in front of it
• Decay in the wisdom tooth or the molar beside it, caused by difficulty cleaning the area
• Crowding or movement of the neighbouring teeth
• Jaw pain or headaches that seem to come from the back of the mouth

Any one of these is a reason to book a wisdom tooth assessment rather than waiting to see if it settles.

What Are Impacted Wisdom Teeth?

An impacted wisdom tooth is one that doesn’t have enough room to erupt correctly. It might grow sideways, at an angle toward the tooth in front, remain partially under the gum, or be completely buried in the jawbone.

Partially impacted wisdom teeth are particularly prone to infection because the gum flap over them traps bacteria and food. Even a fully impacted tooth with no symptoms can sometimes damage the roots of the neighbouring molar over time.

Not all impacted wisdom teeth need immediate removal, but they do need monitoring.

How Dentists Decide Whether Removal Is Necessary

A simple examination and dental X-rays can often provide the answers. According to Healthdirect Australia, a dentist will consider the position of the wisdom tooth, the amount of space available, whether symptoms are present, and whether there’s any risk to surrounding teeth.

At Aura Dentists, the assessment typically involves:

• A clinical examination of the gum and surrounding tissue
• Digital X-rays to see the tooth’s position relative to the nerve, sinuses, and neighbouring roots
• A discussion of your symptoms and how the area is responding
• A review of your oral hygiene in that region

From there, the options are usually to remove the tooth, to monitor it with regular reviews, or to treat any infection first and then reassess. According to the Australian Dental Association, removal is recommended when a wisdom tooth is causing problems or is at clear risk of doing so — not as a matter of course.

What Happens During Wisdom Tooth Removal?

The process varies depending on whether the tooth is fully erupted or impacted.

For a straightforward erupted wisdom tooth, removal is similar to any other tooth extraction — local anaesthetic, a brief procedure, and you’re usually on your way within the hour. For impacted teeth, a surgical extraction involves a small incision in the gum and sometimes sectioning the tooth before removal.

Both are done under local anaesthetic. For patients who are anxious about the procedure, sedation options are available — our general dentistry team can discuss what’s appropriate for your situation at the consultation stage.

Recovery After Wisdom Tooth Removal

Most people are surprised by how manageable recovery is. The first 24–48 hours involve some swelling, discomfort, and soft foods. Ice packs in the first day help reduce swelling. Most patients are back to their usual routine within three to five days.

The Better Health Channel recommends gentle rinsing with warm salt water after the first 24 hours, avoiding smoking, and not using straws — all of which help protect the healing socket.

Full healing of the tissue typically takes two to four weeks, though most people feel functionally normal well before that.

Can You Prevent Wisdom Tooth Problems?

Not entirely — the position your wisdom teeth grow in is largely determined by genetics and jaw size. What you can do is catch problems early:

• Regular dental checkups every six months allow a dentist to track how your wisdom teeth are developing
• Periodic X-rays when recommended give a clear picture of what’s happening below the gumline
• Good oral hygiene around partially erupted wisdom teeth reduces infection risk
• Early assessment when symptoms appear — rather than waiting until an infection takes hold

If you’re experiencing wisdom tooth pain or swelling that concerns you, our emergency dentist is available for same-day care.

The Bottom Line

Wisdom tooth removal isn’t automatically necessary. For some people, wisdom teeth come through without issue and stay that way. For others, impaction, infection, or damage to neighbouring teeth makes removal the right call.

The best decision comes from an individual examination and appropriate imaging — not from what happened to someone else. If you’re in Bayswater or the surrounding area and have questions about your wisdom teeth, contact Aura Dentists to book an assessment. A straightforward conversation and a dental X-ray can usually give you a clear answer.

FAQs

Does everyone need wisdom teeth removed? 

No. Many people keep their wisdom teeth for life without problems. Removal is only recommended when wisdom teeth are causing symptoms, are impacted in a way that creates ongoing risk, or are damaging the neighbouring teeth. Each case is assessed individually.

At what age are wisdom teeth usually removed? 

Wisdom teeth typically appear between 17 and 25. Removal is often easier in younger patients because the roots are less fully developed, but there’s no universal age rule. Assessment is based on the individual situation, not a set age.

Can wisdom teeth stay if they don’t hurt? 

Yes, in many cases. Pain isn’t the only factor — but an asymptomatic wisdom tooth that’s impacted or difficult to clean may still need monitoring. A dentist will assess whether it poses any ongoing risk.

How painful is wisdom tooth removal? 

The procedure itself is done under local anaesthetic and shouldn’t be painful. Some discomfort, swelling, and soreness in the days after is normal and manageable with over-the-counter pain relief in most cases.

How long does recovery take? 

Most people feel noticeably better within three to five days. Full tissue healing takes two to four weeks. The recovery is generally more straightforward than most patients expect.

What happens if impacted wisdom teeth are left untreated? 

Potential consequences include repeated infection, decay in the wisdom tooth or the tooth beside it, damage to adjacent roots, and in some cases cyst formation. Not all impacted wisdom teeth cause these problems, but the risk is why monitoring matters.

When should I see a dentist about wisdom tooth pain? 

If you’re experiencing persistent pain, swelling, difficulty opening your mouth, or signs of infection (throbbing pain, fever, bad taste), book an appointment promptly. Our emergency dentist is available for same-day care if symptoms are acute.
