Wisdom Teeth are the third set of human molars. They usually erupt between the late teens or early twenties. Interestingly, some studies show that more than one third of the global population do not develop them.
Some scientists believe wisdom teeth have become functionless due human evolution and change of feeding and diet habits.
If you belong to the other two thirds of the world population, your wisdom teeth may cause some dental and health issues. It is always a good idea to have your mouth checked by a trusted dentist in order to determine if you have enough room in your jaw for them to erupt in a the correct position.
When Wisdom teeth start to erupt they can push your other teeth causing teeth crowding which will require a more expensive orthodontic treatment later on top of the necessary wisdom teeth extractions - Note this theory is currently under new research as several other studies have found that patients without wisdom teeth still present dental crowding.
Due their position at the end of the mouth, wisdom teeth may be difficult to clean, which can lead them to decay, gum inflammation and infection.
In this scenario, it is possible that a filling, a root canal, or even a tooth extraction is required.
Wisdom teeth can erupt in very odd position, facing forward, backward, sideways, and in very extreme cases, in the area below the tongue, and in many occasions leads to decay on the molars in front of them.
Wisdom teeth could partially erupt, causing a flap of gum tissue to ground over them. This can cause small pieces of food get trapped under this tissue, which lead to harmful bacteria to grow in the area, causing gum inflammation, pain and an infection. If left unattended, severe damage to your gum, nearby teeth and even your jaw bone can occur.
