Wisdom teeth are named for the age they arrive, somewhere between your late teens and mid-twenties, when you are supposedly old enough to know better. Most people find out the hard way that “wisdom” has nothing to do with how much these teeth can actually hurt.
Not every wisdom tooth causes trouble. Plenty of people carry theirs for life without a single issue, while others need them removed to stop pain, infection or damage to nearby teeth before it gets worse.
This guide covers everything worth knowing, from spotting the warning signs to what removal costs and how recovery really feels. Whether you are dealing with jaw pain right now or your dentist has already flagged a problem tooth, here is what to expect.
What Are Wisdom Teeth?
Wisdom teeth, also called third molars, are the last teeth to develop, usually appearing between the ages of 17 and 25. You can find them one in each corner (upper left, upper right, lower left, lower right), though not everyone develops all four.
Some people have one or two, others have none at all, and that is simply genetic variation rather than a sign of a problem.
Human jaws have gradually become smaller over generations due to more processed diets, while our tooth count has stayed exactly the same.
Not every wisdom tooth needs to come out. If yours have erupted straight, sit in a healthy position, and you can clean around them properly, your dentist may simply monitor them at your regular check-ups. Removal becomes necessary when a wisdom tooth is causing pain, infection, decay, gum problems or damage to nearby teeth.
Signs You May Need Wisdom Teeth Removal
Wisdom tooth problems tend to build gradually before they become impossible to ignore.
Here are some of the signs that you need to watch:
- Wisdom tooth pain: A persistent ache or throbbing at the back of your jaw which can get worse when chewing or lying down.
- Swollen or infected gums: Redness, puffiness, or a bad taste around the back molar, which can signal pericoronitis.
- Difficulty cleaning the area: Wisdom teeth are so far back that a toothbrush often cannot reach them properly, allowing plaque and food debris to build up.
- Difficulty chewing or opening your mouth: Swelling and inflammation around an erupting or impacted wisdom tooth can make jaw movement uncomfortable or restricted.
- Repeated infections: Recurring gum infection in the same spot usually means the underlying cause needs to be removed.
- Damage to nearby teeth: A wisdom tooth pushing sideways against your second molar can cause decay, bone loss or crowding in that neighbouring tooth.
If any of this sounds familiar, it is worth getting it properly assessed rather than waiting to see if it settles on its own.
A quick consultation and X-ray will tell you exactly what is going on beneath the surface.
What Are Impacted Wisdom Teeth?
An impacted wisdom tooth does not have enough room to erupt fully or in the correct position. Instead of coming through straight, it can become wedged against the adjacent tooth, angled sideways or trapped entirely under the gum and bone.
Impaction is extremely common. Most adults have at least one impacted wisdom tooth by their mid-twenties.
Dentists generally describe impaction by the direction the tooth is facing:
| Type of Impaction | What It Means |
| Mesial impaction | The tooth is angled forward, pressing into the molar in front |
| Distal impaction | The tooth is angled backward, away from the neighbouring tooth |
| Horizontal impaction | The tooth lies completely on its side beneath the gum |
| Vertical impaction | The tooth is upright but still cannot break through, usually due to lack of space |
| Soft tissue impaction | The tooth has broken through the bone but remains covered by gum |
| Bony impaction | The tooth is still partly or fully encased in jawbone |
How Does Wisdom Teeth Removal Work?
Wisdom teeth removal starts well before you are in the chair. Your dentist will examine your mouth and take a dental X-ray, often a panoramic (OPG) scan, to see the exact position, angle, and root structure of each wisdom tooth. This step determines whether you are looking at a simple or surgical extraction.
- Simple extraction: It is suggested when a wisdom tooth has fully erupted and is accessible above the gum line. Under local anaesthetic, the tooth is loosened and lifted out. It usually takes less time, with some pressure but no pain during the procedure itself.
- Surgical extraction: It is required for impacted or partially erupted wisdom teeth. This may involve a small incision in the gum, removal of a little surrounding bone, and occasionally dividing the tooth into sections for easier removal.
Either way, your dentist will talk you through the anaesthetic options and any risks specific to your case before proceeding.
If you would like a clearer picture of what a tooth extraction procedure generally involves, it is worth reading through the full process beforehand.
How Much Does Wisdom Teeth Removal Cost?
There is no single fixed price for wisdom teeth removal.
It depends on several factors your dentist will assess during your consultation:
- Whether the tooth is erupted or impacted: Impacted teeth requiring surgical extraction generally cost more than a simple extraction.
- The number of teeth being removed: Having multiple wisdom teeth extracted in one visit is usually more cost-effective than separate appointments.
- X-rays and assessment fees: A panoramic X-ray is typically required to plan the extraction properly.
- Whether you have private health insurance: Many extras policies cover a portion of the cost, depending on your level of cover.
At Ashwood Dental, wisdom teeth removal is available from $299, with your exact cost confirmed after an examination and X-ray.

Wisdom Teeth Removal Recovery
Recovery from wisdom teeth removal is gradual. Most people feel noticeably better within a week, though full healing of the extraction site can take several weeks.
- The First 24 to 48 Hours
Expect some swelling, mild bleeding and tenderness as the local anaesthetic wears off. Bite gently on the gauze provided for about 30 minutes, apply a cold compress to your cheek to reduce swelling and rest.
Avoid strenuous activity, since raising your heart rate can increase bleeding and throbbing.
- Days 3 to 7
Swelling and discomfort start easing from around day three. This is when most people return to work or study, provided the job is not physically demanding.
Warm salt water rinses, once the first 24 hours have passed, help keep the area clean and support healing.
Food and Hygiene During Recovery
- Stick to soft foods for the first few days, such as soup, mashed potato, scrambled eggs and smoothies (without a straw, as suction can dislodge the healing blood clot and cause a dry socket).
- Avoid hot, spicy, hard or crunchy foods.
- Continue brushing your other teeth as normal, but be careful around the extraction site.
- Avoid alcohol, smoking and carbonated drinks for at least several days.
- Take any prescribed or recommended pain relief as directed.
Some swelling, mild discomfort and slight jaw stiffness are a normal part of healing.
If anything feels like it is getting worse rather than better after the first few days, that is your cue to get it checked rather than waiting.
When is a Wisdom Tooth Considered a Dental Emergency?
Most wisdom tooth issues can be managed with a scheduled appointment, but certain symptoms cross the line into a genuine dental emergency.
Here are some of the signs that you must not ignore at all costs:
- Severe, worsening pain that is not controlled by pain relief
- Significant facial swelling, particularly if it is spreading toward your eye or neck
- Difficulty breathing or swallowing
- A fever alongside jaw pain or swelling
- Pus discharge or a persistent bad taste suggesting active infection
- Bleeding that will not stop after 24 hours
Conclusion
Wisdom teeth are not automatically a problem, but when they cause pain, infection, or damage to the teeth around them, delaying treatment makes things more difficult.
If you are dealing with wisdom tooth pain, swelling or you are simply due for a check on how yours are developing, do not wait for it to turn into an emergency.

FAQs
How do I know if I need my wisdom teeth removed?
You will usually notice pain, swelling or discomfort at the back of your jaw before an issue is confirmed. Only a dental examination and X-ray can determine whether your wisdom teeth are impacted, decayed or causing problems for neighbouring teeth. If you are experiencing any recurring symptoms, it is best to have this assessed rather than guess.
How much does wisdom teeth removal cost in Melbourne?
Costs vary depending on whether the tooth is simple or impacted, the anaesthesia used, and how many teeth are being removed. At Ashwood Dental, wisdom teeth removal starts from $299, with a firm price confirmed after your consultation and X-ray. Private health insurance may also cover part of the cost, depending on your policy.
What are the signs of an impacted wisdom tooth?
Common signs include pain, swelling, difficulty opening your mouth and gum tenderness near the back molars. Impacted teeth can also cause bad breath, a lingering unpleasant taste or visible crowding of neighbouring teeth. An X-ray is the only reliable way to confirm impaction and its severity.
Can wisdom teeth cause pain, swelling, or infection?
Yes, and this is one of the most common reasons people seek removal. Partially erupted or impacted wisdom teeth create pockets where bacteria and food debris collect, leading to gum infection, swelling, and persistent pain. Left untreated, these infections can spread and become more serious.
How long does wisdom teeth removal take?
A simple extraction can take as little as 15 to 20 minutes, while a surgical extraction for an impacted tooth may take 30 to 60 minutes, depending on complexity. Removing multiple wisdom teeth in one visit extends the appointment but is often more convenient than separate procedures. Your dentist will give you a realistic timeframe after your assessment.
What can I eat after wisdom teeth removal?
Soft, cool to lukewarm foods are best for the first few days, such as yoghurt, soup, mashed vegetables, and smoothies eaten with a spoon rather than a straw. Avoid hard, crunchy, spicy or very hot foods until the extraction site has settled. Most people can gradually reintroduce normal foods within one to two weeks.
Can I have more than one wisdom tooth removed at once?
Yes. It is often recommended if multiple teeth need extraction, since it means one recovery period instead of several. Your dentist will consider your overall oral health, the complexity of each tooth and your comfort with sedation or anaesthetic before advising the best approach. This is worth discussing openly at your consultation.
