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.
If a person has all of their teeth except for their wisdom teeth, their teeth will be numbered 2 thru 15 and 18 thru 31. If a person has had their lower right first molar extracted (tooth #30), the teeth on either side of this tooth space will still keep the numbers 29 and 31. Some people have all four of their second premolars (bicuspids) removed as part of their orthodontic treatment plan.
