Wisdom teeth - what are they?

Wisdom teeth or 3rd molars are the last teeth to form and the last teeth to erupt. Since they are the last teeth to erupt, the decision to keep them or remove them is largely dependant on the amount of space available for them in the mouth after eruption of all other teeth. 

​

The most common reason why the wisdom teeth become impacted is due to inadequate space behind the second molar. The recommendation to remove or keep them is based on their eruption position, ability to keep clean, and the presence of disease such as cavities or gum disease. 

​

​

Other factors to consider: 

​

• The damage the wisdom tooth might cause to the adjacent 2nd molar if it is tipped toward the second molar. The 3rd molar can contribute to cavities, pocket formation, and root resorption of the second molar. 

• The possibility of developing a cyst or tumour formation around the impacted wisdom tooth. However, that is a small percentage (under 2% of cases) and is not generally a reason per se to remove wisdom teeth.

• Wisdom teeth with larger follicular space are strongly recommended for removal. This can be assessed by the dentist using a panoramic or 3-D radiograph. 

• The need to create a space prior to certain orthodontic treatments or prior to some prosthetic or restorative treatment. 

• Recurrent pain or infection associated with wisdom teeth.

​

Major warning signs that you might have an impacted wisdom tooth:

​

• If all of the sudden you start noticing a new kind of pain in the mouth that starts in the back of your jaw and radiates to the ear. 

• Itchy throbbing pain in the back of your jaw. 

• Metallic funny taste in the mouth. 

• Tender, swollen, or puffy gum behind your last molar. 

• Swollen lymph node under your jaw or down the neck is a sign you have an infection.​
