Wisdom teeth removal with new 3D scanning technology

Wisdom teeth removal with new 3D scanning technology
A wisdom tooth often called the "third molar" is the last tooth at the back of each corner of your mouth. They generally erupt between the ages of 17 and 25, although sometimes they appear many years later. People frequently have jaws that are too small for all 32 teeth to fit - 28 is often the most we have room for. 

Why do I need treatment?

Teeth that don't have enough room to erupt into the mouth are called impacted wisdom teeth. They could come out sideways or at a wrong angle. An impacted wisdom tooth may:


  • Grow at an angle toward the next tooth (mesioangular impaction)
  • Grow at an angle toward the back of the mouth (distoangular impaction)
  • Grow sideways at a full 90 degrees into the roots of the molar next to it (horizontal impaction)
  • Grow at the right angle but do not break through the gum line (vertical impaction)

Impacted wisdom teeth are likely to be extracted as they often cause pain, damage to surrounding bone or an infection. They can even cause repeated attacks of infection in the gum surrounding the tooth, this again leads to pain and swelling. If you or a family member is experiencing pain from possible wisdom teeth impaction, please contact our experienced team to book an appointment.

What does the treatment involve?

Wisdom teeth removal is a relatively common procedure, carried out on many patients. When extraction of wisdom teeth is necessary, it will take place at either a dentist's or oral surgeon's clinic.

When the wisdom tooth has not fully erupted into the mouth, it is often necessary to make a cut in the gum over the tooth. Sometimes it is also required to remove some bone surrounding the crown of the wisdom tooth. Rarely the tooth needs to be cut into two or three pieces to be removed. Once the wisdom tooth has been removed the gum is put back into place with stitches. In the majority of cases, these stitches are dissolvable and take around two weeks to disappear. There are a number of anaesthetic options available to patients. The recommended option for you will depend on the expected complexity of the wisdom tooth extraction and your own comfort level.  We offer a local anaesthetic as well as intravenous sedation and general anaesthetic. More difficult wisdom teeth that need to be cut into pieces to remove, can take around 30 minutes.

New 3D scanning technology

PM  Oral Surgery uses cone beam computed tomography (CBCT), the scanner rotates around the patient's head, obtaining up to nearly 600 distinct images, to plan for difficult or high risk wisdom teeth removal. The scanning software then reconstructs a three-dimensional visualisation of the jaw that helps with more accurate surgical planning, compared with panoramic radiography. Our surgery is no longer looking at two-dimensional images but interpreting a three-dimensional picture. Dr Simon Wright believes that seeing things in three dimensions greatly increases patient's understanding of the problem and its location. Also, the use of CBCT potentially reduces patient risk of nerve injury during wisdom teeth surgery.

What to expect after the removal

Although there may be a little bleeding at the time of the extraction, this usually stops very quickly after the surgery. It is important to keep the extraction sites as clean as possible. It may be difficult to clean teeth around the sites of the extraction as it could be sore. If this is the case, it is best to keep the area free from food debris by gently rinsing with an antiseptic mouthwash or warm salt water commencing from the day after surgery.

There likely to be some discomfort and swelling both on the inside and outside of the mouth. This is usually worse for the first three days but it may take up to two weeks before it disappears completely. Patients may also find that their jaw is stiff and we recommend a soft diet for a few days but encourage to return to a normal routine as soon as possible. There may be some bruising of the facial skin that can take up to a fortnight to fade away. Should you have any questions, please contact the PM Oral Surgery on 02 9745 4066.
