Wisdom teeth usually appear between the age of 18 and 25, marking the final end teeth development, but in rare cases they do not even grow.
Overall there are four wisdom teeth, two in the upper part, two in the bottom of the oral cavity and they are occupying practically the last row of the dental arch.
Often, the wisdom teeth cannot grow in regular way as other teeth, so that their appearance can cause discomfort, and in many cases, inflammations in various forms.
Given that they are the last teeth in the jaw, there is a very often problem that there is simply no space for their growth, so that their further development would just cause damage to the firmness of nearby teeth, problems in chewing and in general pain when moving the jaw.
Wisdom teeth extraction process is not a required process; it is something which is decided by the dentist after having made a dental X-ray, after which he will have a broader impression of whether or not to intervene.
