WISDOM TEETH

WHAT ARE WISDOM TEETH?

Wisdom teeth, also known as third molars, are the last teeth to develop, and tend to be appear in the late teens or early 20s. Most people have all 4 wisdom teeth, however occasionally some are missing, and sometimes they do not develop at all. 

Our prehistoric human ancestors had much larger jaws, and therefore they had enough space for wisdom teeth to grow through (erupt) normally. Evolutionary and diet changes now mean that we don’t require our wisdom teeth, and often there is not enough room for them to completely erupt. 

The term impacted is used to describe a wisdom tooth that is stuck in the jaw, or erupts in an abnormal position, due to a lack of space.

CAN WISDOM TEETH BE LEFT?

 

A wisdom tooth can be kept in place if it: 

  • Has erupted completely

  • Is normally aligned

  • Functions normally without pain

  • Is not affected by decay or gum disease

  • Can be easily maintained with normal oral hygiene measures

If the decision is made to leave your wisdom teeth in place, then you will need to continue to see your dentist for regular check-ups, cleaning, and x-rays to ensure that these wisdom teeth don’t develop problems. 

WHEN DO WE NEED TO REMOVE WIDSOM TEETH?

 

Wisdom teeth may need to be removed if they are

  • Impacted

  • Painful

  • Infected 

  • Developing cavities 

  • Causing gum disease

  • At risk of damaging neighbouring teeth 

  • Difficult to keep clean and maintain long term

  • Getting in the way of orthodontic treatment

An impacted, or partially impacted, wisdom tooth can cause jaw pain, gum inflammation, food trapping, and bad breath. Your Oral and Maxillofacial Surgeon will determine the need for wisdom tooth removal by assessing the position of your wisdom teeth, checking your overall oral health, and taking x-rays. 

Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner
