The ideal age for wisdom teeth removal can vary from patient to patient since tooth development is different from person to person. This can vary from the teenage years to the twenties.
The only way to know is to have an examination and radiograph taken to determine the stage of development of the third molars and whether or not they are at risk for pathology or if there is active pathology present. I recommend that patients in their teens have a consultation and radiograph performed to determine if or when they should be extracted.
