Usually between the ages of 17-25, an age that we mature in life and “gain wisdom”.
[/wpspoiler][wpspoiler name=”Do we need Wisdom Teeth?” style=”wpui-green”]

The diet of early prehistoric humans was much rougher and tougher hence we needed more molar teeth. Our jaws used to be much larger, giving more space for these wisdom teeth.

Our ancestors used to lose our teeth at a younger age and these wisdom teeth also serve like “spare tires” to replace teeth that are lost or worn away.

However, our modern diet is much softer, our jaws much smaller and we tend to keep all our teeth till we are old.

Therefore there is usually no space for these wisdom teeth to grow and they tend to get stuck halfway (Impacted).

  • They get infected, and become swollen and painful.
  • They are difficult to clean, and become decayed
  • They act as food trap, and cause decay on the neighbouring tooth.
  • They can cause teeth in front to become crowded.
  • They can develop into cysts.

  • Generally if your wisdom teeth cause problems as described above, they should be taken out.

  • The American Association for Maxillofacial Surgeons estimates that 85% of Wisdom Teeth are taken out.

Your dentist will do a thorough examination and diagnosis to determine if your wisdom tooth requires a minor surgery to remove.

Many times an X-ray will be taken to check the position of the Wisdom Tooth.

Before surgery, your dentist will discuss the procedure with you and inform you what to expect.

The surgery will be performed carefully under local anaesthesia.

After the Wisdom Tooth has been removed the area will be stitched together and antibiotics and painkillers will be prescribed.

What to do after Wisdom Tooth operation?

If you have undergone a wisdom tooth surgery, please adhere to the following:

  1. Continue biting with firm pressure on the gauze for another one to two hours. Change the gauze when it becomes soaked with blood.
  2. Do not rinse your mouth, consume hot drinks or eat hot food after the operation.
  3. Following the use of local anesthesia, the lips, tongue or cheeks may remain numb for 3 to 4 hours, during which time they may be damaged by biting.
  4. You may have swelling or bruising on your face where the surgery was performed. The swelling will disappear in a few days time.
  5. If you are a smoker, please refrain from smoking after the operation.
  6. Do not engage in strenuous activities for at least four to five days after the operation.
  7. You are advised to consume soft food for the next two to three days. Rinse your mouth with antiseptic mouthwash or warm salt water after every meal.
  8. If bleeding recommences:
    • Rinse your mouth once with cold water, then fold a piece of gauze (or a cotton handkerchief) into a tight pad and place directly over bleeding point. Apply firm steady pressure on pad by biting on it for 30 minutes.
    • Repeat this procedure twice if bleeding persists. If this fails, return to the clinic for professional assistance.
  9. Take the medication as prescribed. If rashes develop, stop taking the medication and contact the dentist immediately.
  10. Brush your teeth as per normal. Take care not to brush too hard near the wound area.
  11. In the event of an emergency (e.g. non-stop and excessive bleeding, high fever), please call the dentist immediately. If the dentist cannot be reached, please seek emergency treatment at the Accident & Emergency Department at any hospitals as soon as possible.
  12. Please remember to visit the dentist in about a week’s time to get the sutures removed.
