Wisdom teeth are the last teeth to develop and typically emerge during the late teenage years or early adulthood. While some wisdom teeth grow normally without causing problems, many become impacted or fail to erupt properly, leading to discomfort, infection and other dental complications. At Dentists @ Canning Vale, we provide comprehensive wisdom tooth assessments and removal services to help protect your oral health and prevent future problems. Our dental team will carefully evaluate your wisdom teeth and recommend the most appropriate course of action based on your individual circumstances. Important: Wisdom tooth removal is a surgical procedure that carries potential risks and complications. This page provides general information only and does not constitute dental or medical advice. Individual outcomes vary. A thorough clinical assessment, including dental X-rays, is required before any treatment decisions are made. If you are concerned about your wisdom teeth, please book a consultation with our team.

What Are Wisdom Teeth?

Wisdom teeth are the third molars located at the back of the mouth. Most people develop four wisdom teeth, although some individuals may have fewer or none at all. Wisdom teeth usually begin to emerge between the ages of 17 and 25 - a period traditionally associated with gaining maturity, which is how they acquired their name.

Why Do Wisdom Teeth Cause Problems?

Modern jaws often do not have sufficient space to accommodate wisdom teeth properly. Combined with changes in our diet and evolutionary changes in jaw size, this means wisdom teeth are more likely to cause problems now than in previous generations. As a result, wisdom teeth may:

• Become impacted beneath the gum and bone
• Erupt at an angle against neighbouring teeth
• Partially emerge through the gum, creating a pocket that traps bacteria
• Push against and damage the teeth in front of them
• Become difficult or impossible to clean adequately

These issues can increase the risk of pain, infection and long-term damage to surrounding teeth and bone.

Common Signs That May Indicate a Wisdom Tooth Problem

You may benefit from a wisdom tooth assessment if you experience:

• Pain or aching at the back of the mouth
• Swollen, red or tender gums around the back teeth
• Jaw discomfort or stiffness
• Difficulty opening your mouth fully
• Persistent bad breath
• Recurring infection around a wisdom tooth
• Food consistently becoming trapped at the back of the mouth
• Headaches or facial pain associated with jaw pressure

In some cases, wisdom teeth can create problems without producing obvious symptoms, which is one reason regular dental examinations and X-rays are important even when you feel no discomfort.

When Is Wisdom Tooth Removal Recommended?

Not all wisdom teeth need to be removed. Teeth that are healthy, fully erupted and functioning normally may be safely monitored over time. However, removal is often recommended in the following circumstances:

Decay

Saliva, bacteria and food particles can collect around a partially erupted wisdom tooth, making it and the tooth in front of it prone to decay. This type of decay is often difficult to treat effectively, and pain and infection usually follow without intervention.

Gum Infection (Pericoronitis)

When a wisdom tooth is only partially erupted, bacteria can accumulate beneath the overlying gum flap and cause a localised infection. This may result in pain, swelling, bad breath and limited jaw opening. Once an initial episode of pericoronitis occurs, further episodes tend to become more frequent and more severe.

Pressure and Crowding

Erupting wisdom teeth can exert pressure on neighbouring teeth, potentially causing pain and contributing to crowding. In some cases, the teeth immediately in front of the wisdom tooth may be gradually eroded by sustained pressure.

Orthodontic Reasons

Patients who have undergone orthodontic treatment may find that erupting wisdom teeth place pressure on straightened teeth, potentially compromising the results of treatment. Your dentist will advise whether removal is appropriate based on your individual situation.

Prosthetic Reasons

Patients who wear dentures may be advised to have wisdom teeth removed before or after denture construction. A wisdom tooth erupting beneath a denture can cause significant irritation and may require the denture to be relined or remade.

Cyst Formation

A fluid-filled cyst can develop from the tissue surrounding an unerupted wisdom tooth. If left untreated, cysts can cause bone destruction, jaw expansion and damage to adjacent teeth. Surgical removal of both the cyst and the tooth is usually necessary to prevent further bone loss.

Types of Wisdom Tooth Impaction

An impacted wisdom tooth is one that cannot fully erupt into its correct position due to lack of space, obstruction by bone, gum or an adjacent tooth, or the angle at which it is developing.

Fully Impacted

The tooth remains completely beneath the gum and bone and does not emerge at all.

Partially Impacted

Part of the tooth crown has emerged through the gum, but the remainder is still trapped beneath the tissue or bone.

Horizontal Impaction

The wisdom tooth is growing sideways and pressing directly against the tooth in front of it. This is one of the more complex impaction types to manage.

Angled Impaction

The tooth is erupting at an angle, either tilted toward or away from the adjacent tooth rather than growing vertically into position.

Wisdom Tooth Assessment at Dentists @ Canning Vale

Before recommending any treatment, our dentists perform a thorough assessment to evaluate the position, development and overall condition of your wisdom teeth.

Clinical Examination

We assess your teeth, gums and surrounding tissue and discuss any symptoms you are experiencing.

Digital X-Rays

Digital imaging allows us to evaluate the precise position of wisdom teeth relative to the nerve canals and adjacent teeth, information that is essential for safe treatment planning.

Treatment Discussion

We will explain our findings, outline your options and discuss whether removal is recommended, advisable or whether a monitoring approach is more appropriate in your case.

What to Expect During the Procedure

Local Anaesthetic

Most wisdom tooth removals are carried out under local anaesthetic to keep you comfortable throughout the procedure. You will feel pressure during the removal but should not experience sharp pain. Let your dentist know immediately if you do.

Sedation

For patients who are anxious, or where the procedure is more complex, sedation options may be discussed. Our team can explain what is available and what is most appropriate for your circumstances.

The Removal

The complexity of the procedure depends on the position and anatomy of the tooth. Fully or deeply impacted wisdom teeth typically require a more involved surgical approach than a straightforward erupted tooth. Your dentist will explain the expected procedure before commencing.

Aftercare Instructions

Written aftercare instructions will be provided. Following these carefully is important to support healing and reduce the risk of complications.

Risks and Possible Complications

Wisdom tooth removal is a common procedure, but like all surgical interventions it carries potential risks. Published dental literature indicates that the overall incidence of complications following wisdom tooth removal is approximately 5 to 10 per cent. Understanding these risks before proceeding is an important part of giving informed consent.

Infection

Bacteria are naturally present in the mouth and can cause infection at the surgical site after removal. Antibiotics are prescribed where clinically indicated, and maintaining good oral hygiene helps reduce this risk. Signs that may indicate infection, including swelling, pain and restricted jaw opening lasting more than seven days after surgery, should be reported to your dentist promptly.

Dry Socket

A dry socket occurs when the blood clot that normally forms in the extraction socket is lost or fails to develop properly. This typically causes severe, persistent pain beginning two to three days after removal. It is not an infection and is not dangerous, but requires treatment. Smoking significantly increases the risk of dry socket and patients are advised not to smoke before or after wisdom tooth removal.

Nerve Involvement

Lower wisdom teeth are often positioned in close proximity to two important nerves: the inferior alveolar nerve, which provides sensation to the lower lip and chin, and the lingual nerve, which provides sensation to the tongue. Despite every precaution being taken, these nerves can occasionally be affected during removal of lower wisdom teeth. This may result in temporary or, in rare cases, prolonged numbness, tingling or altered sensation in the lip, chin or tongue. Digital X-rays and, where indicated, cone beam CT imaging help identify cases where nerve involvement is a higher risk. Your dentist will discuss this with you before treatment.

Sinus Communication

The roots of upper wisdom teeth are often closely associated with the floor of the maxillary sinus. When an upper wisdom tooth is removed, there is a small risk that an opening between the mouth and the sinus is created. In most cases this heals without intervention, but in some situations a further procedure may be needed to close it.

Jaw Joint Discomfort

Keeping the mouth open during surgery can occasionally cause temporary strain on the jaw joints. This may result in mild discomfort around the jaw joint area for a short period following the procedure. Applying warmth to the area and taking appropriate anti-inflammatory medication (as recommended by your dentist) usually resolves this within seven to ten days.

Prolonged Bleeding

Some residual oozing from the surgical site is normal in the first few hours following removal. If bleeding persists or is significant, apply gentle pressure with a clean gauze pad for approximately thirty minutes. If bleeding does not settle, contact our clinic for advice. Recovery varies between patients and depends on the complexity of the removal and the number of teeth extracted. Most people begin to feel significantly more comfortable within three to five days, though complete healing takes longer. Common post-operative experiences include:

• Swelling, typically peaks on the second day and then gradually reduces over the following three to four days. Applying an ice pack to the side of the face for the first eight hours (twenty minutes on, twenty minutes off) can help limit swelling.
• Discomfort, pain medication will be recommended or prescribed. Most patients find that discomfort is well managed with appropriate analgesia.
• Jaw stiffness, this usually resolves as swelling subsides. Eating softer foods during this period is advisable.
• Bruising, some patients develop bruising around the jaw and neck, which is normal and not a cause for concern.
• Minor bleeding, a small amount of blood-tinged saliva in the first 24 hours is expected.

Detailed written aftercare instructions will be provided following your procedure. If you have any concerns during your recovery, please do not hesitate to contact our clinic. It is recommended by dental specialists that where impacted wisdom teeth require removal, the procedure is ideally performed between the ages of 14 and 22. At this stage, the roots are not yet fully formed, recovery tends to be faster and the risk of complications is lower. The procedure becomes technically more complex with increasing age.
