Your Wisdom Teeth Need To Be Pulled Out?

Wisdom teeth (third molars) are artifacts of evolution. Thousands of years ago, our ancestors needed a third molar at 18-20 years old in order to survive. Nowadays, as we keep all our teeth healthy, the third molars often lack the needed place to erupt normally.

Wisdom teeth should be extracted due to:

  • Lack of space.
  • Avoid potential infection: partially erupted allowing infiltration of bacteria
  • Negative pressure: poor alignment of wisdom teeth
  • Risk of cyst formation
  • GUM infection surrounding the wisdom teeth

The ideal time slot for the wisdom of surgery is between age 18 and 30 years. The recovery period is about 48 hours.

Treatment: Extraction

Consultation and panoramic x-rays are necessary to determine the procedures to consider and the evaluation of the risks of surgery. It is often possible to do all extractions in a single appointment.

To remove all four wisdom teeth within a SINGLE APPOINTMENT of 60-90 minutes reduce the risks of complication and infection. It also have the enormous benefit of getting everything done within a single appointment and the healing process is simplified (compare to multiple appointments for extraction).

Wisdom Teeth Post-Operation & Risks

After Surgery Instructions

Bite on cotton for 45 minutes to allow the formation of a blood clot. The blood clot that forms immediately after surgery, allows for better healing. It is the loss of the first clot that can cause complications such as bleeding, pain and post-operative infections.

The goal is to avoid any action that could dislodge the blood clot. Here is a list of actions to be avoided for a period of 2 to 3 days after surgery:

  • avoid spitting
  • avoid rinsing the mouth
  • avoid smoking
  • avoid physical exercise, intense effort
  • avoid spicy food or too hot

If for any reason the clot is lost and bleeding resumes, bite on a moistened tea bag directly on the wound and keep a constant pressure for at least one hour. This will form a new blood clot. If bleeding persists, contact your dentist or a medical authority.

To reduce swelling, apply ice every 15 minutes on the cheeks in the hours following surgery. It is important to space the periods of application of ice 45 minutes otherwise, the effect is reversed. By application of ice, there is a decreased blood flow which results in a reduction of inflammation, thereby reducing swelling. However, if the ice is applied too long, inflammation is increased in response to the new trauma (cold).

If swelling persists after the first day, apply moist heat. In the days following surgery, the inflammatory reaction is complete, so there is more reason to apply ice. Rather, it should rather apply heat to increase blood circulation to accelerate tissue healing.


Never apply heat on the day of surgery.
The days following the surgery: rinse with water and salt 48 hours after surgery. Repeat 4 to 5 times per day. A some swelling is normal and bruises (blue) may appear on the skin and disappear in 5 to 7 days.

Perhaps you have difficulty opening the mouth, this problem should subside after 4 to 5 days. To reduce discomfort, apply heat on the second day after surgery. If the problem persists beyond a week, contact your dentist.

If there are antibiotics to be taken: follow the dosage as prescribed and do not forget to finish the entire prescription even when there is more pain. Discontinuation of antibiotics can create resistant bacteria that make ineffective, the future use of these antibiotics.

For all other information please contact your dentist as soon as possible.

Risks and Possible Complications

  • INFECTION: an antibiotic may be prescribed by the dentist, if necessary.
  • ALVEOLITIS: a temporary complication, when there is loss of the initial blood clot. Characterized by intense pain, a bad taste in the mouth and sometimes difficulty opening the mouth. Dry socket can last several days and can be relieved by applying a tea bag. If pain persists, contact your dentist.
  • PARATHESIA: During a tooth extraction, the nerve is rarely touched. If that’s the case, this can cause a loss of sensitivity, affecting the tongue or lower teeth. This loss of sensation is rare and usually temporary. Only exceptional cases can cause permanent damage.

Although it is impossible to eliminate all risks, our dentists by fields of expertise can reduce the risk of complication through their daily experience and specific vocation.
