These are the third molars, which appear around 17 and 21 years and are the
last teeth to appear. The name derives from the fact that this is the age
at which worldly wisdom is attained.
When they come through correctly, healthy wisdom teeth can help you chew
food, but when there is not enough space in the arch then the wisdom teeth
get impacted or they may erupt in an abnormal pathway and cause problems.
Impacted teeth are the teeth, which are trapped inside the jawbone or soft
tissue.
Wisdom teeth that aren’t in the right position can make it difficult to
floss. This can lead to accumulation of food particles, which makes them
prone for cavities.
Wisdom teeth that have partially erupted may cause deep periodontal pockets
and in turn may also lead to pain, swelling and stiffness in your jaw.
Other complications include crowding or damage neighboring teeth or a cyst
may form around an impacted tooth and can damage the nearby vital tooth
structures.
