A great deal of people does not have enough room for these teeth in their jaws.
A short explanation:
Which teeth are wisdom teeth?
Wisdom teeth are the last teeth to appear, approximately from 18th to 25th year. Of all permanent teeth they are the last to grow.
Do all people have to have problems with wisdom teeth?
If they grow normally, no. They actually can be very useful, and with appropriate oral hygiene they can remain healthy for the rest of your life.
What are impacted wisdom teeth?
Because wisdom teeth are the last to grow sometimes there’s no place for them, so only a half of them appears, or they are not visible at all. This type of wisdom teeth are called impacted.
Why are impacted teeth causing problems?
There are a few reasons:
-Cavities. These teeth are extremely hard to clean and keep healthy. Fixing them is also hard because they are hard to reach.
-They damage the tooth next to them. Because of their position cavities can appear on surrounding teeth and even lead to root resorption.
-Over impacted wisdom teeth’s crown there is usually a fold of soft tissue that makes it easy for bacteria to reproduce which in the end leads to infection. That part of the gingiva can be swollen and painful and bad breath is another symptom. It is not rare for the swelling to expand to the cheek or lymph nodes.
-Pushing other teeth forward. Orthodontists often request the extraction of wisdom teeth.
-Cysts. Cysts create a deformity in the bone and require a surgical procedure.
