Wisdom teeth are the last set of molars to come through, usually between the ages of 17 and 25. Not everyone needs them removed, but in many cases, particularly when they are impacted or misaligned, extraction is the safer option. This guide explains when extraction is needed, what the procedure involves, how much it costs in Singapore, and what to expect during recovery.

 

What Are Wisdom Teeth?

Wisdom teeth, also known as third molars, are the four teeth at the very back of the mouth. They are evolutionary leftovers from a time when human jaws were larger. Today, many people do not have enough space in the jaw for them to come through properly, which is why issues are common.

– Most adults have four wisdom teeth, though some people have fewer or none

– They typically erupt in late teens or early twenties

– They can grow straight, tilted, sideways, or remain trapped in the jaw (impacted)

 

When Is Wisdom Tooth Extraction Needed?

Not every wisdom tooth needs to be removed. A dentist will assess the position, the surrounding teeth, and any symptoms before recommending extraction. Common reasons for removal include:

– Impaction: the tooth is trapped beneath the gum or bone and cannot erupt fully

– Pain or swelling around the wisdom tooth or jaw

– Recurring gum infection (pericoronitis) around a partially erupted tooth

– Tooth decay that is difficult to clean or treat due to the tooth’s position

– Damage to the neighbouring molar

– Crowding or pressure on adjacent teeth

– Cysts or other changes seen on a dental X-ray

If a wisdom tooth has come through fully, is well-positioned, and can be cleaned properly, extraction may not be necessary.

 

Signs You May Need a Wisdom Tooth Assessment

It is worth seeing a dentist if you notice any of the following:

– Persistent pain at the back of the jaw

– Swollen or tender gums around the wisdom tooth area

– Bad breath or a bad taste that does not go away

– Jaw stiffness or difficulty opening your mouth

– Recurring infections around the same area

– Headaches or pain that radiates from the back of the mouth

A clinical examination together with a dental X-ray (or sometimes a 3D scan) gives a clear picture of the tooth’s position and any associated issues.

 

Simple Extraction vs Surgical Extraction

Wisdom tooth removal generally falls into two categories. The dentist will recommend the approach based on the tooth’s position and condition.

 Simple Extraction

A simple extraction is suitable when the wisdom tooth has fully erupted and is accessible. The tooth is loosened and removed with instruments, similar to any other routine extraction. It is usually completed under local anaesthesia.

 

Surgical Extraction

A surgical extraction is needed when the tooth is impacted, partially erupted, or positioned in a way that makes simple removal difficult. The procedure may involve:

– A small incision in the gum to access the tooth

– Removing a small amount of bone around the tooth

– Sectioning the tooth into smaller pieces for easier removal

– Stitches to close the area after extraction

Surgical extraction is performed by a dentist or oral surgeon, typically under local anaesthesia. Sedation may be offered for patients with anxiety or for complex cases.

 

The Wisdom Tooth Extraction Procedure Step-by-Step

While each case is different, most wisdom tooth extractions follow a similar process.

1. Consultation and X-ray: the dentist assesses the tooth’s position and discusses the procedure and recovery

2. Local anaesthesia: the area around the tooth is numbed so the procedure is not painful

3. Extraction: the tooth is loosened and removed, either simply or surgically depending on the case

4. Stitches: dissolvable stitches may be placed to help the gum heal

5. Gauze and aftercare instructions: a gauze is placed to control bleeding and you are given home-care instructions before leaving

The procedure itself usually takes 20 to 60 minutes depending on complexity.

 

Wisdom Tooth Extraction Cost in Singapore

The cost of wisdom tooth extraction in Singapore depends on several factors, including the complexity of the case, the type of anaesthesia used, and whether it is done at a private clinic or a public institution.

Public institutions and polyclinics may offer lower fees, particularly for subsidised patients.

 

Can MediSave Be Used for Wisdom Tooth Extraction?

Yes, in most cases. Surgical wisdom tooth extraction is generally claimable under MediSave, as it is classified as a day surgery procedure. The amount that can be claimed depends on the procedure code and the patient’s MediSave balance, subject to MediSave withdrawal limits set by the Ministry of Health.

Simple extractions of fully erupted wisdom teeth are usually not MediSave-claimable.

It is best to confirm MediSave eligibility and the exact claim amount with your dental clinic before the procedure.

 

Wisdom Tooth Recovery Timeline

Recovery from wisdom tooth extraction varies from person to person, but the general timeline is as follows.

Some clinics issue medical leave (MC) for one to a few days after surgical extraction, depending on the procedure and recovery.

 

Risks and When to Call Your Dentist

Wisdom tooth extraction is a common procedure, but as with any surgery there are some risks. Your dentist will explain these in detail before the procedure. Possible complications include:

– Prolonged bleeding

– Infection

– Dry socket (when the blood clot dislodges from the extraction site)

– Temporary numbness in the lip, tongue, or chin

– Damage to adjacent teeth or restorations

 

Contact your dentist if you experience:

– Severe or worsening pain after a few days

– Pus or a foul taste from the extraction site

– Persistent bleeding that does not slow down

– Fever or significant facial swelling

– Numbness that does not improve as expected

 

Frequently Asked Questions About Wisdom Tooth Extraction

Is wisdom tooth extraction painful?

The procedure itself is performed under local anaesthesia, so you should not feel pain during the extraction. Some pressure may be felt. Mild discomfort and swelling after the procedure are common and are usually managed with prescribed pain relief.

How long does the procedure take?

Most extractions take between 20 and 60 minutes, depending on the position of the tooth and whether it is impacted.

Do I need to be put to sleep for wisdom tooth removal?

Most cases are done under local anaesthesia while you are awake. Sedation or general anaesthesia may be offered for complex cases, multiple extractions, or patients with significant anxiety.

How many days of MC will I get?

This depends on the complexity of the procedure and how you are recovering. Surgical extractions commonly come with a short period of medical leave. Your dentist will advise based on your case.

What can I eat after wisdom tooth extraction?

For the first few days, stick to soft, cool, and lukewarm foods such as porridge, mashed potato, soup, yoghurt, smoothies, and scrambled eggs. Avoid spicy, crunchy, sticky, and very hot foods until the area has healed.

When can I exercise again after the procedure?

Light activity is usually fine after a couple of days, but strenuous exercise should be avoided for about a week as it can increase bleeding and swelling. Your dentist will give specific advice.

Will I need all four wisdom teeth removed at once?

Not necessarily. Some patients have all four removed in one session, especially under sedation, while others have them removed one or two at a time. The decision depends on the position of the teeth, your overall health, and your preference.

What is dry socket and how can I prevent it?

Dry socket is a painful condition where the blood clot at the extraction site is dislodged or fails to form, exposing the bone. To reduce the risk, avoid smoking, using straws, vigorous rinsing, and spitting forcefully in the first few days after extraction.

Can wisdom teeth grow back after removal?

No. Once a wisdom tooth has been fully extracted, it does not grow back.

Thinking About Wisdom Tooth Removal? Get an Assessment First

The decision to remove a wisdom tooth depends on its position, your symptoms, and the long-term outlook for the tooth. A consultation with a dentist, supported by an X-ray, gives a clear picture of whether extraction is needed and what type of procedure is most suitable.
