🦷 Complete Wisdom Tooth Guide

Everything you need to know about wisdom tooth extraction

A comprehensive guide to wisdom tooth removal in Singapore — types of impaction, procedure steps, risks, recovery timeline, costs, Medisave coverage, and answers to common questions.

UNDERSTANDING WISDOM TEETH

What are wisdom teeth?

Wisdom teeth (also called third molars) are the last set of teeth to develop, typically emerging between the ages of 17 and 25. Most adults have four wisdom teeth — one in each corner of the mouth.

While some wisdom teeth grow in without any issues, many don't have enough room to emerge properly. When this happens, they can become impacted — meaning they're trapped beneath the gum line or growing at an angle. Impacted wisdom teeth are one of the most common dental conditions in Singapore.

Why do wisdom teeth cause problems?

  • Impaction — The tooth is trapped in the jawbone or gum tissue, sometimes growing sideways towards the adjacent tooth
  • Crowding — Emerging wisdom teeth can push against neighbouring teeth, causing misalignment
  • Infection (pericoronitis) — Partially erupted wisdom teeth create a flap of gum tissue where bacteria can accumulate, leading to painful infections
  • Decay — Wisdom teeth at the very back of the mouth are difficult to clean properly, making them prone to cavities
  • Cyst formation — In rare cases, impacted wisdom teeth can develop cysts that damage the surrounding bone

Not all wisdom teeth need to be removed. Your dentist will assess your X-rays and recommend extraction only when there is a clear clinical reason.

TYPES OF IMPACTION

How wisdom teeth become impacted

The type of impaction determines the complexity of the extraction. Your dentist will identify this from your X-ray.

Mesial Impaction

Most common

The wisdom tooth is angled towards the front of the mouth, pushing against the second molar. This is the most frequently seen type and often causes pressure, pain, or damage to the adjacent tooth. Usually requires surgical extraction.

Vertical Impaction

Correct angle, stuck position

The tooth is in the correct upright orientation but is stuck below the gum line, often because there isn't enough space for it to erupt fully. May or may not require surgical extraction depending on how deeply it is embedded.

Horizontal Impaction

Most complex

The wisdom tooth lies completely sideways, parallel to the jawbone. This type is the most complex to remove as the tooth is typically fully embedded in bone and pressing directly against the roots of the adjacent tooth. Always requires surgical extraction.

Distal Impaction

Least common

The tooth is angled towards the back of the mouth, away from the second molar. This is the rarest type of impaction. While it may not directly affect adjacent teeth, it can still cause problems with the surrounding gum tissue and may need removal.

Your dentist will take an X-ray (OPG) during your consultation to determine the type and severity of impaction. This assessment is essential for planning the safest and most comfortable extraction approach for your case.

TYPES OF EXTRACTION

Simple vs surgical extraction

The type of extraction depends on how your wisdom tooth has grown. Here's how they compare.

Simple Extraction

For wisdom teeth that have fully erupted above the gum line and can be removed with standard dental instruments.

From $150
per tooth, before GST
CHAS SUBSIDIES
  • Tooth has fully erupted
  • Straightforward removal
  • Local anaesthesia
  • Shorter procedure (15–20 min)
  • Faster recovery (3–5 days)
  • CHAS subsidies may apply

Surgical Extraction

For impacted wisdom teeth that are partially or fully trapped beneath the gum line or jawbone.

$0*
*after Medisave (up to $1,250 claimable per tooth)
MEDISAVE CLAIMABLE
  • Tooth is impacted or partially erupted
  • May involve bone removal
  • Local anaesthesia
  • Longer procedure (30–45 min)
  • Recovery 1–2 weeks
  • 100% Medisave claimable

Your dentist will take an X-ray (OPG) during your assessment to determine whether a simple or surgical extraction is needed. Most impacted wisdom teeth in Singapore require surgical extraction, which is fully claimable under Medisave.

SIGNS & SYMPTOMS

Signs you may need extraction

If you notice any of these, it's a good idea to schedule a dental assessment.

😬

Pain or tenderness

Recurring or persistent pain at the back of your jaw, especially when chewing or opening your mouth wide.

🔴

Swollen or bleeding gums

Red, swollen gums around the wisdom tooth area, sometimes accompanied by bleeding when brushing.

🦠

Repeated infections

Pericoronitis — a recurring gum infection around a partially erupted wisdom tooth causing pain and swelling.

🦷

Damage to adjacent teeth

An impacted wisdom tooth growing sideways can push against and damage the tooth next to it.

🔄

Crowding

Wisdom teeth can shift your other teeth out of alignment, especially if you've had braces or orthodontic treatment.

💬

Bad breath or taste

Persistent bad breath or an unpleasant taste can indicate food trapping or infection around a wisdom tooth.

WHAT TO EXPECT

The extraction process

Here's what happens from your first visit to full recovery.

🔍

Pre-op assessment

Your dentist will examine your mouth and take an X-ray (OPG) to assess the position and type of impaction of your wisdom teeth. You'll receive an honest recommendation and a clear breakdown of costs — including Medisave and CHAS deductions.

💉

The procedure

Local anaesthesia is administered to ensure you feel no pain during the extraction. For simple extractions, the tooth is loosened and removed with dental instruments. For surgical extractions, a small incision may be made in the gum, and the tooth may be sectioned for easier removal. Stitches are used to close the site.

30–45 minutes for surgical, 15–20 for simple
🧹

Immediate aftercare

Your dentist will place gauze on the extraction site. You'll receive detailed aftercare instructions, prescribed medications (antibiotics and painkillers), and a follow-up appointment for suture removal if needed. We'll WhatsApp you the next day to check in.

You can go home the same day

Review appointment

A follow-up visit is scheduled within 1 to 2 weeks to check healing, remove stitches, and ensure you're recovering well. If you have concerns at any point before your review, you can WhatsApp us.

Follow-up in 1–2 weeks

Most surgical extractions are fully covered by Medisave. Check your eligibility.

RISKS & COMPLICATIONS

Possible risks to be aware of

Wisdom tooth extraction is a routine and safe procedure. However, as with any surgery, there are some risks. Your dentist will discuss these with you before proceeding.

🔥

Dry socket

Occurs when the blood clot at the extraction site is dislodged, exposing the bone. Causes significant pain 2–3 days after surgery. Prevented by avoiding straws, smoking, and vigorous rinsing.

🧠

Temporary nerve numbness

Lower wisdom teeth sit close to the inferior alveolar nerve. In rare cases, extraction may cause temporary numbness or tingling in the lip, chin, or tongue. This is usually temporary and resolves within weeks to months.

🦠

Infection

Post-operative infection can occur at the extraction site. Symptoms include increasing pain, swelling, fever, and pus discharge. Antibiotics are prescribed to minimise this risk.

💧

Bleeding

Some bleeding is normal in the first 24 hours. Biting on gauze for 30–45 minutes helps. If bleeding is heavy or persistent beyond 24 hours, contact your dentist.

👀

Sinus communication (upper teeth)

Upper wisdom teeth sit near the sinus cavity. In rare cases, extraction may create a small opening. This usually heals on its own, but your dentist will provide specific instructions if it occurs.

💪

Jaw stiffness

Difficulty opening your mouth fully (trismus) is common after surgery, especially for lower wisdom teeth. This is temporary and resolves within 1–2 weeks with gentle jaw exercises.

Serious complications are rare. Your dentist will review your X-ray and discuss any specific risks based on the position of your wisdom teeth before proceeding with extraction.

RECOVERY TIMELINE

Day-by-day recovery guide

What to expect during your recovery from wisdom tooth extraction. Most patients feel significantly better within 5–7 days.

Day 0

Surgery day

Numbness wears off in 2–4 hours. Bite on gauze for 30–45 minutes. Apply ice pack 20 min on/off. Take prescribed medication. Rest.

Day 1

Swelling begins

Some swelling and bruising is normal. Continue ice packs. Eat soft, cool foods. Avoid spitting or using straws. Gentle salt water rinse after 24 hours.

Day 2–3

Peak swelling

Swelling peaks and may cause stiffness. Switch from ice to warm compress. Continue soft diet and medication. Most patients can return to work or school.

Day 4–5

Turning the corner

Swelling starts to subside. Pain decreases noticeably. You can start reintroducing semi-soft foods. Gentle brushing near the extraction site.

Day 6–7

Feeling better

Most discomfort is gone. Stitches removed at your review appointment. Light exercise may resume.

Week 2–4

Full healing

Extraction site continues to close. Gradually return to normal diet. Full healing of the soft tissue takes about 2–4 weeks. Bone remodelling continues for several months.

Recovery tips for faster healing

🍲

What to eat

Stick to soft foods for the first 24–48 hours: porridge, yoghurt, mashed potatoes, soup, and smoothies. Gradually return to normal foods as the site heals. Avoid chewing on the extraction side.

💊

Pain management

Take the prescribed pain medication as directed — don't wait for the pain to kick in. Apply a cold compress to the cheek (20 minutes on, 20 minutes off) to reduce swelling in the first 24 hours.

🚫

What to avoid

No smoking or vaping for at least 48–72 hours. Avoid using straws (suction can dislodge the blood clot), hot food, spicy food, alcohol, and strenuous exercise for 2–3 days.

FAQ

Common questions about wisdom teeth

How much does wisdom tooth extraction cost in Singapore?

+
At Trust Dental Surgery, surgical wisdom tooth extraction costs $350 to $1,250 per tooth, which is fully Medisave claimable (up to $1,250) — meaning $0 out-of-pocket for most patients. Simple extractions (non-surgical) start from $150. Costs may vary depending on the complexity of the case.

Can I use Medisave for wisdom tooth surgery?

+
Yes. Surgical wisdom tooth extraction is 100% Medisave claimable at Trust Dental Surgery. You can claim up to $1,250 per tooth from your Medisave, so most patients pay $0 cash out-of-pocket. You can use your own Medisave or an immediate family member's. We handle all the Medisave claim paperwork for you. For a full breakdown, visit our Medisave claims guide.

How long is the recovery after wisdom tooth extraction?

+
For simple extractions, most patients recover within 3 to 5 days. For surgical extractions of impacted wisdom teeth, recovery typically takes 1 to 2 weeks. Swelling usually peaks around day 2 to 3 and gradually subsides. Most patients can return to work or school within 1 to 2 days after simple extraction and 2 to 3 days after surgical extraction.

Is wisdom tooth extraction painful?

+
The procedure itself is painless as it is performed under local anaesthesia. You may feel some pressure but no pain during the extraction. After the anaesthesia wears off, some discomfort and swelling is normal, which is managed with prescribed pain medication. Most patients describe it as far less painful than they expected.

What are the different types of wisdom tooth impaction?

+
There are four main types: Mesial impaction (angled towards the front of the mouth — most common), Vertical impaction (tooth is in correct orientation but stuck below the gum), Horizontal impaction (tooth lies completely sideways — most complex), and Distal impaction (angled towards the back of the mouth — least common). Your dentist will determine the type from an X-ray and recommend the appropriate extraction approach.

What is the difference between simple and surgical extraction?

+
A simple extraction is performed when the wisdom tooth has fully erupted through the gum and can be removed with standard dental instruments. A surgical extraction is required when the tooth is partially or fully impacted beneath the gum or bone, and involves making a small incision and sometimes removing a small amount of bone to access the tooth. Surgical extractions are claimable under Medisave; simple extractions are not.

Should I remove all 4 wisdom teeth at once?

+
It depends on your individual case. Some patients prefer to remove all four at once to minimise recovery periods, while others opt for one side at a time (2 teeth per session) for a more comfortable recovery. Your dentist will assess your X-rays and recommend the best approach based on the position and condition of each wisdom tooth.

What are the risks and complications of wisdom tooth extraction?

+
Wisdom tooth extraction is a routine procedure, but possible risks include dry socket (blood clot dislodged from extraction site), temporary numbness of the lip or tongue if the tooth is close to a nerve, infection at the extraction site, and minor bleeding. Serious complications are rare. Your dentist will discuss any specific risks based on your X-ray findings before the procedure.

What can I eat after wisdom tooth extraction?

+
For the first 24 to 48 hours, stick to soft, cool foods such as porridge, yoghurt, mashed potatoes, and smoothies. Avoid hot, spicy, or crunchy foods, and do not use a straw as the suction can dislodge the blood clot. You can gradually return to your normal diet as the extraction site heals, usually within a week.

What are dry sockets and how can I prevent them?

+
A dry socket occurs when the blood clot that forms in the extraction site is dislodged or dissolves before the wound has healed, exposing the underlying bone. This can cause significant pain. To prevent dry sockets, avoid using straws, spitting, smoking, and vigorous rinsing for the first 24 to 48 hours after extraction. Follow your dentist's aftercare instructions closely.

How soon can I return to work after wisdom tooth extraction?

+
Most patients return to work or school within 1 to 2 days after a simple extraction, and within 2 to 3 days after a surgical extraction. If your job involves physical labour, you may need additional rest. Your dentist can provide a medical certificate if needed. Swelling typically peaks on day 2 to 3, so plan accordingly.

Can I drive home after wisdom tooth surgery?

+
If your procedure is done under local anaesthesia, you may be able to drive home, though we recommend having someone accompany you as the numbness and mild discomfort can be distracting. If sedation is used, you must not drive for at least 24 hours and should arrange for someone to take you home. It is generally safer to take a taxi or have a companion drive you.

Will I be sedated during wisdom tooth surgery?

+
Wisdom tooth surgery at Trust Dental is performed under local anaesthesia, which numbs the area completely so you feel no pain. You remain fully awake during the procedure. If you experience dental anxiety, discuss your concerns with your dentist so additional comfort measures can be arranged.

Can I smoke or vape after wisdom tooth extraction?

+
You should avoid smoking and vaping for at least 48 to 72 hours after extraction, ideally longer. Smoking creates suction that can dislodge the blood clot, leading to a painful dry socket. The chemicals in smoke and vapour also slow down healing and increase the risk of infection. The longer you can abstain, the better your recovery will be.

What happens if I don't remove a problematic wisdom tooth?

+
Leaving a problematic wisdom tooth untreated can lead to recurring infections (pericoronitis), damage to adjacent teeth, cyst formation in the jawbone, worsening pain, and tooth decay. In some cases, the problems may worsen over time, making the eventual extraction more complex. However, not all wisdom teeth need to be removed — only those causing or likely to cause issues.

Is it safe to extract wisdom teeth during pregnancy?

+
Elective dental procedures including wisdom tooth extraction are generally postponed until after delivery. However, if you are experiencing severe pain, infection, or an emergency, your dentist may recommend treatment during the second trimester when it is safest. Always inform your dentist if you are pregnant or planning to conceive.

Can I use CHAS or Medisave for wisdom tooth extraction?

+
Surgical wisdom tooth extraction is covered under Medisave (up to $1,250 per tooth), not CHAS. Simple (non-surgical) extractions are CHAS claimable — up to $38.50 for anterior teeth and $78.50 for posterior teeth for Pioneer Generation cardholders. CHAS Blue, Orange, and Merdeka Generation cardholders also receive subsidies at lower rates. Bring your CHAS card and NRIC to your appointment. See our full CHAS subsidy guide for details.

Can I brush my teeth after wisdom tooth extraction?

+
Yes, you should continue brushing your other teeth on the same day, but avoid the extraction site for the first 24 hours. After 24 hours, gently brush around the area using a soft-bristled toothbrush. Be careful not to disturb the blood clot. After 24 hours you can also rinse gently with warm salt water to keep the area clean.
