Why Do We Have Baby Teeth?
"Most other vertebrates, i.e., fishes and reptiles, have teeth that come and go on an incoming and ongoing basis. This is a boon to all those tropical trinket tourist traps that sell necklaces with shark teeth. A given fish or reptile has a set of teeth that are pretty much all the same."

Milk Teeth and the Replacement of Teeth
"Elephants eat a very abrasive diet, and the teeth wear strongly as they move forward. By the time the tooth is lost, it is largely worn away. Generally only two teeth are active at any time. Elephants have a maximum of six cheek teeth on each side of the upper and lower jaws; captives often live beyond the time when they lose their last tooth and must be fed a diet of soft materials."

Eruption Charts
"Teeth vary in size, shape and their location in the jaws. These differences enable teeth to work together to help you chew, speak and smile. They also help give your face its shape and form."
