WISDOM TEETH OR THIRD MOLARS
Wisdom teeth, also called “third molars”, usually appear between late teens and late 20s. Most people have four wisdom teeth, although some have fewer and some a few more. Often there is insufficient space and this can result in a long struggle for the teeth to appear. During this time, they may cause painful repeated gum infections.
Also, as is often the case, they may be growing crooked and trap plaque (germs) inside the gum next to the neighbouring tooth. When this happens, decay can occur in an important chewing molar.
