Extractions & Wisdom Tooth Surgery
A wisdom tooth extraction is a routine procedure to remove third molars that may cause pain or complications. These teeth often emerge at odd angles or remain impacted, leading to discomfort, infection, or misalignment. During your routine dental checks or orthodontic consultation, we will evaluate whether an extraction is necessary to maintain your oral health. Our team ensures a smooth, comfortable procedure with a focus on your comfort and recovery.
A dental extraction refers to the process of tooth removal or tooth “pulling”. We know how hard it is to say goodbye. During your orthodontic consultation with us, we will assess whether there is any way to save the tooth before making the final decision for tooth removal.
Why Do Wisdom Teeth Become Impacted?
Wisdom teeth are the last set of molars to emerge, typically appearing between the ages of 17 and 25. Due to limited space in the jaw, they may not erupt properly, leading to impaction. This can cause discomfort and oral health concerns.
Lack of Space – The modern human jaw is often too small to accommodate wisdom teeth, causing them to grow at odd angles or remain trapped under the gums.
Obstruction by Other Teeth – If existing teeth block the wisdom tooth’s path, it may only partially emerge or stay hidden beneath the gumline.
Abnormal Growth Direction – Some wisdom teeth grow sideways, diagonally, or even backward, increasing the risk of impaction and dental crowding.
Thick Gum Tissue – Dense gum tissue can make it difficult for wisdom teeth to break through, leading to partial eruption and discomfort.
Why do I need an extraction?
Extractions are usually a last resort when a tooth is deemed irreparable. This could mean that the tooth is either too damaged by decay or the tooth support has been destroyed by gum disease. Sometimes extractions are needed in order to straighten teeth during braces treatment. Book a consultation with us today to find out whether you need an extraction.
What is the extraction process like?
Your comfort is important to us. Before the extraction, our dentist will calmly walk you through the procedure. To make your experience as painless as possible, we begin by placing a layer of numbing cream on your gums before applying an anaesthetic solution. Once your tooth and gums are completely numb, our dentist will proceed to carefully and skillfully loosen the tooth and remove it.
Potential Complications From Wisdom Teeth and When Should You Consider Wisdom Tooth Extraction?
Wisdom teeth may need to be removed if they cause discomfort or pose a risk to oral health.
Severe Gum Pain and Swelling
Impacted wisdom teeth can lead to persistent pain, gum swelling, and tenderness. When partially erupted, they trap food and bacteria, increasing the likelihood of infection and inflammation of the gums.
Damage to Nearby Teeth
A misaligned wisdom tooth can push against neighbouring teeth, causing shifting, decay, or structural damage of the roots. This may result in costly restorative dental work, or even extraction of the neighbouring tooth.
Orthodontic Considerations
In some instances, wisdom teeth may contribute to dental crowding, affecting the alignment of straightened teeth after orthodontic treatment. Removing them may help maintain results.
Difficulty Chewing or Speaking
If wisdom teeth grow at an improper angle, they may make chewing uncomfortable or cause irritation to the inner cheek or tongue.
Sinus Issues
Infection from upper wisdom teeth can spread to the nearby sinuses, leading to congestion, sinus pain, or frequent infections. Extraction may alleviate these symptoms.
Increased Risk of Decay
Impacted wisdom teeth can be hard to clean, making them more prone to cavities and infection.
Jaw Cysts or Tumours
In rare cases, impacted wisdom teeth can lead to the formation of cysts, which may damage the surrounding bone or teeth.
Headaches or Jaw Pain
Inflammation from an infected impacted wisdom teeth can contribute to headaches, TMJ issues, and jaw stiffness.
Wisdom Teeth Removal
Wisdom teeth - the third molars at the back of our mouths - are the last teeth to grow out. They usually appear around the age of 18. Our wisdom teeth aren’t the smartest with navigation — they often grow out in the wrong positions! When they are prevented from growing out normally, they are impacted.
Wisdom tooth impaction, adapted from British Association of Oral & Maxillofacial Surgeons
Wisdom teeth often remain partially or totally covered, that’s why we often require an x-ray to check for their presence and position. We will carefully analyse the x-ray and advise whether it needs to be removed, and if so, whether it requires an extraction or minor surgery.
Why do you need to remove impacted wisdom teeth?
Impacted wisdom teeth tend to trap food and consequently, bacteria. This can lead to decay and gum infection (periocoronitis), affecting both the wisdom tooth as well as its neighbouring teeth.
Some research has suggested that the developing wisdom tooth may lead to misalignment of the front teeth. After your braces treatment, we may also suggest the removal of your impacted wisdom teeth to prevent your newly-aligned teeth from becoming crooked.
Benefits of Removing Your Wisdom Teeth
Extracting problematic wisdom teeth can improve oral health and prevent future complications.
Reduced Pain and Discomfort
Eliminating impacted wisdom teeth alleviates swelling, gum irritation, and persistent pain. This not only enhances overall comfort but also prevents recurring dental issues. Removing these teeth early can spare you from long-term complications, reducing the need for future dental treatments.
Lower Risk of Gum Infection and Decay / Improved Oral Hygiene
With no wisdom teeth trapping food particles, you reduce the risk of bacterial buildup, which helps prevent gum infection and decay. A cleaner oral environment contributes to healthier gums, fresher breath, and fewer oral complications. Additionally, with fewer hard-to-reach areas, brushing and flossing become easier, supporting long-term oral hygiene and reducing the need for more complex dental treatments.
Prevents Misalignment
Wisdom teeth can push against existing teeth, causing unwanted shifting. By removing them, you preserve your orthodontic results and maintain a well-aligned smile. This is especially beneficial for those who have undergone braces or Invisalign treatment.
Reduce Risk of Sinus Infection, Headaches and Jaw Pain That May Be Caused by Infected Wisdom Teeth
Impacted or infected wisdom teeth can contribute to sinus pressure, tension headaches, and jaw discomfort. Removal can relieve these symptoms and reduce strain on nearby structures like the temporomandibular joint (TMJ), helping you feel more comfortable and improving your overall wellbeing.
Prevention of Cysts and Bone Damage
Wisdom teeth that remain impacted can lead to cysts, which may erode bone structure and cause severe dental complications. Early extraction prevents these issues, safeguarding both teeth and jaw health.

What Happens During Wisdom Tooth Extraction?
The procedure is designed to be as smooth and comfortable as possible.
Step 1: Numbing the Area
A layer of numbing cream, followed by an anaesthetic solution, is first applied. In some cases, sedation options may be available for added comfort.
Step 2: Accessing the Tooth
We will carefully expose the wisdom tooth by gently moving aside the gums. If needed, a small portion of bone that covers the teeth may be removed to facilitate extraction.
Step 3: Tooth Removal
Depending on its position, the wisdom tooth may be extracted in one whole piece or divided into sections for easier removal. This method minimises discomfort and ensures a more comfortable extraction process.
Step 4: Closing the Site
After the wisdom tooth extraction, the gums are repositioned, and resorbable stitches may be placed to help with healing. Gauze is applied to control bleeding and promote clot formation.
Potential Risks of Wisdom Tooth Extraction
While the procedure is commonly performed with minimal complications, some risks may arise.
Swelling, bruising and Discomfort
Mild swelling and tenderness are common after the procedure. Applying an ice pack and taking prescribed painkillers can help manage discomfort. Swelling usually peaks within the first 48 hours before subsiding.
Bleeding
Some bleeding is expected in the first 24 hours. Biting down on gauze can help control it. Avoid spitting or using straws, as they can dislodge the blood clot and prolong healing.
Dry Socket
If the blood clot protecting the extraction site is lost prematurely, it may expose the underlying bone, causing intense pain and delayed healing. Rinsing gently and avoiding tobacco use can help prevent this condition.
Nerve Sensitivity
In some cases, temporary numbness or tingling in the lips, tongue, or chin may occur due to nerve proximity and injury. Most cases resolve naturally within a few weeks to months.
