Wisdom Teeth Removal

Wisdom tooth removal in Singapore may be recommended when a wisdom tooth is impacted, partially erupted, difficult to clean, or causing problems such as pain, swelling, infection or decay. At Dr Mike Teoh Dental Clinic, we assess each wisdom tooth individually and discuss whether monitoring, routine extraction or surgical removal is appropriate.

about Wisdom teeth

Wisdom teeth, also known as third molars, are the last teeth at the back of the mouth. They usually develop during the late teens or early adulthood and may erupt normally, remain partially erupted, or become impacted beneath the gum or jawbone. Impacted wisdom teeth do not always require removal, but they may cause problems depending on their position and the surrounding teeth and structures.

When Is Wisdom Tooth Removal Needed?

Lower wisdom teeth can sometimes lie close to important anatomical structures, including the inferior alveolar and lingual nerves. Their position and relationship to nearby structures are assessed before surgery so that the appropriate treatment approach and potential risks can be discussed.

Why do we take them out?

Wisdom tooth removal may be recommended when the tooth is causing disease or is at significant risk of causing problems. Because wisdom teeth are located at the back of the mouth, partially erupted or impacted teeth can also be difficult to keep clean. Problems may include:

Wisdom Tooth Assessment and Removal

Before wisdom tooth removal, the position of the tooth and its relationship to nearby structures are assessed. A 2D dental X-ray is often sufficient, but in selected cases where the roots of a lower wisdom tooth appear closely related to the inferior alveolar nerve, a 3D CBCT scan may be considered when the additional information could affect treatment planning.

When is a 3D CBCT scan needed?

CBCT provides a three-dimensional view of the wisdom tooth, surrounding jawbone and nearby anatomical structures. This can help your dentist better understand the relationship between the tooth roots and the inferior alveolar nerve and plan an appropriate treatment approach.

How are wisdom teeth removed?

Wisdom tooth removal depends on whether the tooth has fully erupted or remains partially or completely impacted. The appropriate approach is determined after assessing the tooth’s position, surrounding bone, adjacent teeth and nearby anatomical structures.

Our Commitment to Your Smile

Routine Extraction

Fully erupted wisdom teeth can often be removed with a routine dental extraction under local anaesthesia.

Surgical Removal

Impacted or partially erupted wisdom teeth may require surgical removal. Depending on the tooth's position, a small amount of surrounding bone may be removed and the tooth may be divided into smaller sections to facilitate removal.

After Removal

The area is cleaned and stitches may be placed where appropriate. Post-operative instructions are provided to help manage discomfort and swelling and support healing.

What are the risks of wisdom tooth removal?

Wisdom tooth removal is a commonly performed dental procedure, but as with any treatment, there are potential risks. These vary depending on the position of the tooth, its roots and nearby anatomical structures. Your dentist will assess these factors and discuss the relevant risks with you before treatment.

Pain, swelling and bruising — Some discomfort, swelling and bruising are expected after wisdom tooth removal and usually improve as healing progresses
Dry socket — Occasionally, the blood clot within the extraction site may be disrupted, resulting in increased pain and requiring further treatment.
Infection or delayed healing — Infection or delayed healing can occasionally occur following wisdom tooth removal.
Nerve injury — Lower wisdom teeth may be close to nerves supplying sensation to the lower lip, chin and tongue. Altered sensation can occur and may be temporary or, less commonly, permanent.
Damage to adjacent structures — Nearby teeth, fillings, crowns and other anatomical structures can potentially be affected during removal.

What is recovery like after wisdom tooth removal?

Recovery after wisdom tooth removal varies depending on the complexity of the procedure and the individual. Some pain, swelling and jaw stiffness are common after surgical removal and generally improve as healing progresses. Your dentist will provide specific post-operative instructions based on your treatment.

First 24 hours — Bite on the gauze as instructed and avoid vigorous rinsing, spitting or disturbing the extraction site.
Swelling and discomfort — Swelling may increase during the first few days before gradually settling. Take any prescribed or recommended medication as directed.
Eating and drinking — Start with softer foods and avoid very hot, hard or sharp foods around the surgical site during the early healing period
Oral hygiene — Keep your mouth clean while being gentle around the extraction site. Follow the specific brushing and rinsing instructions provided by your dentist.
When to contact us — Contact the clinic if you experience persistent heavy bleeding, worsening swelling or pain after initial improvement, fever, difficulty swallowing or breathing, or any other symptoms that concern you.

Frequently Asked Questions About Wisdom Tooth Removal

Here are answers to some common questions about wisdom tooth removal. Your dentist can advise you more specifically after examining your wisdom teeth and reviewing any necessary dental X-rays.

Do all wisdom teeth need to be removed?

No. Wisdom teeth do not necessarily need to be removed if they are healthy, functional and can be adequately cleaned. Removal may be considered when they are causing problems such as pain, recurrent infection, decay, gum disease or damage to an adjacent tooth.

Is wisdom tooth removal painful?

Local anaesthesia is normally used to numb the area during treatment. You may feel pressure or movement, but the procedure should not be painful once adequate anaesthesia has been achieved. Some discomfort, swelling and jaw stiffness can occur afterwards and usually improve as healing progresses.

How long does wisdom tooth removal take?

This varies considerably depending on the position and complexity of the tooth. A straightforward extraction may be relatively quick, while an impacted wisdom tooth requiring surgical removal can take longer. Your dentist can give you a better estimate after examining the tooth and X-rays.

How long does it take to recover after wisdom tooth surgery?

Recovery varies between individuals and with the complexity of the procedure. Swelling and discomfort are often most noticeable during the first few days and then gradually improve. Your dentist will provide post-operative instructions appropriate to your treatment.

When is a CBCT scan needed for wisdom teeth?

A routine 2D dental X-ray is often sufficient. In selected cases, particularly when the roots of a lower wisdom tooth appear closely related to the inferior alveolar nerve, a 3D CBCT scan may be considered if the additional information could affect treatment planning.

Can I eat after wisdom tooth removal?

Yes, but softer foods are generally more comfortable during the early healing period. Avoid very hot, hard or sharp foods around the surgical site and follow the specific instructions provided by your dentist.

When should I contact the dentist after wisdom tooth removal?

Contact the clinic if you experience persistent heavy bleeding, worsening swelling or pain after initial improvement, fever, difficulty swallowing or breathing, or anything else that concerns you.

Can Medisave be used for wisdom tooth surgery?

Medisave may be used for eligible surgical wisdom tooth removal procedures, subject to prevailing CPF rules and withdrawal limits. The amount that can be claimed depends on the procedure performed. Our clinic can advise you on the estimated Medisave claim after your dentist has assessed the tooth and recommended the appropriate treatment.
