Wisdom Teeth Extraction

Wisdom Teeth Extraction


Third molars, more commonly known as “wisdom teeth” are the last 4 teeth of the 32 teeth that surface in the mouth. Most times, they appear around the ages of 17-25 years old.
Wisdom teeth can be found at the back of the mouth, both top and bottom close to the throat. They are called ‘’wisdom teeth’’ because they appear at the time an individual is beginning to reach maturity.
Sometimes in some individuals, wisdom teeth do not appear and function properly as a result of inadequate space in the mouth. They may become stuck (impacted) in a potentially dangerous or undesirable position.

Degrees or Types of Impaction of the Teeth Within the Jaw
  • Soft tissue impaction: in soft tissue impaction, the crown of the tooth develops through the bone, but it is covered by the gum (gingival). This may encourage trapping of food below the gum which may result in tooth decay or infection. Swelling and pain may also result from soft tissue impaction.
  • Partial Bony Impaction: In this situation, there is a partial eruption of the tooth but some parts of the crown appears below the surrounding jaw bone and the gum. Infection may also result as there is difficulty in cleaning the area.
  • Complete Bony Impaction: In this form of impaction, the jaw bone completely encloses the tooth. This can be removed with more complicated technique.
Reason to Remove Wisdom Teeth

It is not mandatory to remove wisdom teeth. However, there are several reasons why a person needs to undergo this dental procedure. For example, removal of wisdom teeth is done as a result of swelling, pain, infection, decay or as a measure to prevent serious problems that may arise in the future. There may be harmful implications if wisdom teeth are left untreated and these include:

  • Damage to nearby teeth:The second molars are the teeth that appear directly before the wisdom teeth. These may be affected by impacted wisdom teeth leading to tooth decay, possible bone loss or periodontal disease.
  • Disease:Although it’s not a common occurrence, tumours and cyst may penetrate areas around the impacted wisdom teeth.
  • Tooth Crowding: Other teeth may become misaligned as a result of pressure put on them by impacted wisdom teeth. This misalignment is also known as twisting or crowding. This theory, however, is not acceptable by every dental professional.
Wisdom Teeth Examination

Like every other dental procedure, a thorough examination is done by your dentist to observe surrounding teeth and wisdom teeth. The dentist may order a digital or panoramic X-ray to properly analyze the wisdom teeth and pinpoint any problems.
Wisdom Teeth Examination may also reveal decay or deterioration of nearby teeth. Evaluation and treatment of impacted wisdom teeth are usually recommended. This is to ensure early identification of potential problems. A thorough examination determines the best option to take by the dentist on impacted wisdom teeth.

What does the removal of wisdom teeth involve?

The removal of wisdom teeth is very common and can be done under local anaesthesia. Patients may choose an oral sedation if they want to be more relaxed while the procedure is going on. A patient may be permitted to go home the same day after the surgery. Guidance and post-operative medications will be given to the patient to manage any discomfort or swelling.
