Wisdom Tooth

Wisdom teeth are the third molars; the last pair of back teeth used to chew that are located in each mouth, to give four wisdom teeth. These are the last teeth to emerge in the gums and usually do so between the ages 17 and 25 or near the age of achieving the majority. This is the reason why these teeth are called wisdom teeth as they appear during the phase of life called the "age of wisdom."

Common Types of Impacted Wisdom Tooth


  • Mesial impaction: The tooth angled from too far towards the front of the mouth. It is one of the most common types of impact.

  • Vertical impaction: These teeth come fairly straight however, there is not enough room in mouth to accommodate it.

  • Horizontal impaction: Teeth impacted horizontally by lying on their side.

  • Distal impaction: Distally impacted teeth that are titled to the back of the mouth.

  • Soft tissue impaction: It occurs when the tooth gets erupted through the gums.

  • Bony impaction: When your tooth is completely within the bone.


Common Problems associated with the Wisdom Tooth:


  • 1. Swelling of the face: swelling of the face, throat and ear can occur when the teeth pierce the gum. But swelling may be due to pericoronitis.

  • 2. Swollen lymph nodes: patients may experience pain in the throat. This is because the teeth affect the lymphatic glands under the jaw.

  • 3. Inflammation of the Gums: When the wisdom tooth pierces, the torn gum lets bacteria enter and can become inflamed.

  • 4. Cysts or tumors: tumors or cysts may form around the wisdom teeth not yet erupted, but such an event is quite rare.

  • 5. Difficulties in brushing: If you have difficulty using floss and toothbrush, it is quite possible that your wisdom tooth is responsible.

  • 6. Chewing Problems: The wisdom tooth not yet erupted may eventually lead to ulcers in the mouth. When this happens, chewing becomes a Herculean task.


Why extract wisdom teeth?


From the historical point of view, there are various hypotheses concerning the problem related to the teeth of wisdom:


Some people agree that due to human evolution, the bones of the jaw are now shorter and less bulky than before, which leaves less room for the eruption of the teeth most the back of the jaws;


Others believe that changes in the use of our teeth and improved dental health mean that all our teeth remain in the mouth longer than before and that there is insufficient space for wisdom teeth.


Be that as it may, because of the location of the wisdom teeth and the current shape of our jaws, little space remains available to allow these teeth to come out and be in good position.


Wisdom Tooth Extraction


The wisdom tooth extraction is often a feared operation. We all have the image of a neighbor, a sister or a colleague with swollen cheeks and the obligation to eat ice and nothing else for two or three days. The procedure requires the incision of the gum and then the practitioner will clear the tooth by milling the bone. It may be necessary to cut the tooth before removing it. The gingiva is closed with resorbable stitches that disappear in less than 3 weeks.


The duration of wisdom tooth extraction varies but is on average 15 to 30 minutes per tooth. The practitioner then gives you instructions that you must follow to the letter.
