Humans have 32 teeth. A person develops two sets of teeth within their whole life span. The first set is known as ‘baby teeth’ or ‘primary teeth’ which will begin to be lost by six or seven years old. By the time one reaches 18 years, they generally have their full set of ‘adult teeth’ or ‘permanent teeth’.
Yours is Unique
No two people have identical sets of teeth—your teeth are as exclusive as your fingerprint. Teeth are sometimes very useful for forensics.
Communication with Brain
A structure called cementum is what wraps the root of the tooth and secures the tooth in the gum. Enamel wraps the part of the tooth above the gum. This highly-protected region is known as the pulp. The nerve endings inside the pulp is what communicates with the brain.
Dentists generally advise to keep your toothbrush at least six feet away from your toilet to avoid airborne particles from getting on your toothbrush from flushing.
In a life span, the normal person produces about 100,000 gallons of saliva. As people age, their salivary secretions reduce making them more vulnerable to dental diseases.
Some Don't Loose Baby Teeth
By age 3, the normal child has a full set of 20 primary or ‘baby’ teeth. These small chiclets loosen and ultimately fall out as the permanent or ‘adult’ teeth begin to erupt. If a person doesn’t have a replacement permanent or ‘adult’ tooth, that baby tooth will not loosen, it will stay put.
Teeth By Born
Approximately one in every 2,000 babies are born with teeth. Ouch!
