What are wisdom teeth?

  • Wisdom teeth, also called "third molars", are found at the very back of your mouth and are the last teeth to come in.
  • They have been called wisdom teeth because they usually appear during the late teen years, which have been called the "age of wisdom".
  • Wisdom teeth do not make you smarter, but they can be painful and give you problems. You may not get all four wisdom teeth.

Should wisdom teeth be removed?

  • Not everyone’s wisdom teeth need to come out.
  • Wisdom teeth that become trapped in the jaw bone are called "impacted" and may need to be removed. Consult a dentist or oral care provider for more information.

What are the symptoms associated with wisdom teeth?

You may experience:

  • Pain
  • Swelling
  • Headaches
  • Sore throat
  • Difficulty opening your mouth
  • Pus coming from the gum ( gum infection )
  • Tooth decay/cavities  (wisdom teeth that are partially out of the gum are prone to decay)

See an oral care provider if your teen has any of these symptoms, or have any other concerns.

Of all the body parts, the mouth area is injured the most during contact sports. Wearing a mouthguard (PDF file) (order resource) while active is a simple but effective way of protecting teeth.

What does a mouthguard do?

  • A mouthguard acts like a shock absorber that helps to protect and cushion your teeth, lips mouth and jaw when playing contact sports.
  • Wearing a mouthguard can help prevent serious injuries like broken jaws, chipped teeth and cuts to your tongue and cheeks.

When is wearing a mouthguard a good idea?

  • During any sport where the mouth is at risk for injury. A few examples are hockey, basketball, football, soccer and wrestling.

How to take care of a mouthguard

  • Rinse your mouthguard under cool water after each use and air dry.
  • Occasionally clean it with a mild soap and water.
  • Check your mouthguard regularly. If it shows signs of wearing down, tearing or cracking, it must be replaced. If it is custom made contact your dental professional.

What are the different kinds of mouthguards?

Choosing a mouthguard is very important. There are three types of mouthguards to choose from.

  • Custom-made 
    They are made by a dental professional and are individually designed, which ensures the best fit.
  • Self-adapted 
    They can be purchased in most sports stores. They are moulded to fit the mouth by boiling the mouthguard in water and then biting into the warm plastic. They can feel bulky and interfere with breathing and speaking.
  • Ready-made 
    They can be purchased in most sports stores. They come in many different shapes and sizes, but little can be done to adjust the mouthguard to fit your mouth properly. They are often too bulky, loose, and uncomfortable and can interfere with breathing and speaking.
