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.
In humans, there are usually 20 primary (baby) teeth and 28 to 32 permanent teeth, the last four being third molars or wisdom teeth, each of which may or may not grow in. Among primary teeth, 10 usually are found in the maxilla (upper jaw) and the other 10 in the mandible (lower jaw).
