People today ascribe a number of meanings to the Eye of Horus, including protection, wisdom, and revelation. It is often associated with the Eye of Providence found on US $1 bills and in Freemasonry iconography.
The crown, or visible part of the tooth, forms before the roots do. Eventually, the 20 primary teeth are replaced by 32 permanent teeth. The primary molars are replaced by permanent premolars (also called bicuspids) and the permanent molars come in behind the primary teeth. Most often, the first teeth to emerge are the lower two front teeth (incisors) and the upper and lower first molars, the molars closest to the front of the mouth. They are followed by the upper two front teeth.
Between 6 to 12 years of age, the roots of these 20 baby teeth degenerate, allowing their replacement with 32 permanent adult teeth. The third molars (wisdom teeth) have no preceding baby version and generally erupt in mid to late adolescence.
