Also called "third molars". They are the last series of tooth to erupt. There is usually one wisdom tooth on each corner of your mouth so there are four wisdom teeth in total. They start to erupt between the age of 16 years to 25 years olds.

However  when they do so , they generally  cause problems. There is also often  not enough room for them to grow and so they become impacted (through evolution our jaw is getting smaller).

Infection	crownding	decay/ erosion

What are the possible problems caused by wisdom teeth?

• Infection caused by build up of plaque and bacteria
• gum diseases
• damage such as caries of the adjacent tooth (second molar)
• crowding or displacement of other teeth
• cysts or tumour development

When should wisdom teeth be removed?

It is now recommended by specialists to remove impacted wisdom teeth between the ages of 14 and 22 years even if they do not cause any problems, as at this age range people tend to recover quicker and surgery is easier and the risk of complications are small.

So it is always a good idea to have your wisdom teeth checked even before they cause any problems.
