Wisdom Tooth Surgery
What are Wisdom Teeth?
Wisdom teeth are the third molars, the last teeth that erupt in the mouth.
Usually between the ages of 17-25, an age that we mature in life and "gain wisdom". Females can expect slightly younger eruption,even at about 16 years old.
What are the problems with Impacted Wisdom Teeth?
There are many theories attempting to explain why wisdom teeth get impacted (‘stuck’ by adjacent structures like jaw bone and second molar). Whatever the reason, the outcome is lack of space for these wisdom teeth to grow, hence they get impacted. They are difficult to clean, act as food trap and will lead to the following problems:
  • The gums overlying impacted wisdom teeth get infected, and become swollen. This is a painful condition called ‘pericoronitis’.
  • They cause decay on the second molar tooth in front.
These are the most important reasons for their removal.
Are there any instances where Wisdom Teeth do not need removal?
Wisdom teeth need not be removed if:
  • you are born without them (congenitally missing);
  • the teeth are fully erupted and in occlusal function (biting with each other) and completely buried in the jaw bone without communication at all with the oral cavity. However, cysts or tumours can develop from buried teeth and if so, that will be an indication for removal.
How will my Wisdom Teeth be taken out?
Your dentist will do a thorough clinical and radiographic examination to determine if your wisdom tooth requires a surgery to remove.

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

The surgery can be performed under local anaesthesia alone, sometimes with sedation.

After the surgery, the area will be stitched together, and antibiotics and painkillers will be prescribed.

Typically, a one week follow up appointment will be scheduled and the stitches will be removed then. You will also be taught how to cleanse the wound/socket till it heals completely in order to prevent food and debris contamination.
After Wisdom Tooth Surgery
If you have undergone a wisdom tooth surgery, please adhere to the following:
  1. 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. 2. Do not rinse your mouth, consume hot drinks or eat hot food after the operation.
  3. 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. 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. 5. If you are a smoker, please refrain from smoking after the operation.
  6. 6. Do not engage in strenuous activities for at least four to five days after the operation.
  7. 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. 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. 9. Take the medication as prescribed. If rashes develop, stop taking the medication and contact the dentist immediately.
  10. 10. Brush your teeth as per normal. Take care not to brush too hard near the wound area.
  11. 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. 12. Please remember to visit the dentist in about a week's time to get the sutures removed.
