"Wisdom teeth," also known as the third molars, often come in impacted or otherwise unfit to stay in the mouth. This is usually a problem between the ages of 17 and 25. Knowing what to eat after wisdom teeth removal, however, depends on the nature of the surgery and how your mouth reacts to the extractions following the procedure.
The American Association of Oral and Maxillofacial Surgeon (AAOMS) recommends patients have their wisdom teeth out if there is active infection present in the form of gum disease or irrepairable tooth decay, or if there are cysts, tumors or pathology present in the area around the tooth. In addition, if an impacted wisdom tooth does damage the neighboring teeth, it's best to extract it rather than wait for it to cause bigger issues. The process of planning usually begins with a dental X-ray to evaluate the areas of interest, and ends with the extraction of one, two or even all four wisdom teeth.
