What are wisdom teeth? – Wisdom tooth extraction 
Wisdom teeth often known as third molars are the last teeth to erupt. One usually gets them in late teens or early twenties. However, even instances of eruption in late adulthood are common. If they erupt smoothly and without any interruption, then they can be proved as an asset. But the problem with third molars is that in case they do not erupt properly or are misaligned, they would need to be extracted. If they are poorly aligned, then they can damage the adjacent teeth.
What problems can a wisdom tooth cause?

 It is also possible that wisdom tooth is impacted. This means that the wisdom teeth remain intact in the soft tissue and partially break or erupt through gums.
If they remain partially open, then the chances of bacteria entering the tooth are high which may cause infection & lead to the swelling in the jaw, pain and general illness. 
Because of the misaligned positioning of the jaw, it will become difficult to brush or floss making the tooth prone to decay and gum disease.
There is 4 set of wisdom teeth two on each upper and lower jaw.
Nowadays majorly due to lifestyle changes people do not get wisdom teeth. This is because the jaws do not develop completely & properly which restrain the wisdom teeth to erupt. Contact Us For – wisdom tooth extraction
