This happens because differentiated teeth is what God wanted.
Yes, reptile teeth are usually undifferentiated. Human teeth are differentiated into incisors, molars, premolars, and canines.
Birds do not have teeth. Mammals have differentiated teeth while the teeth in the mouth of a given reptile are more or less the same except for the fangs of venomous snakes.
Being partially differentiated, or not terminally differentiated.
Mammals get pregnant; reptiles lay eggs. Additionally, mammals have fur, feed their young milk, and usually walk on vertical legs, have differentiated teeth, and are warm-blooded. Reptiles have scales, generally do not care for their young, walk with their legs splayed (except for snakes and some lizards, which have none), do not have differentiated teeth, and are cold-blooded.
Teeth shape is determined by their function. Pointed teeth, like canines, are used for biting and tearing food. Flat-topped teeth, like molars, are used for grinding and crushing food. The variation in tooth shape allows for efficient food processing.

Removable bridges or removable partial dentures are appliances made to replace one or more missing teeth in an arch. Removable bridges all use the same type of tooth material but are differentiated by the materials used to hold the teeth to the partial denture and the way the partial denture attaches to the two (or more) teeth left in the arch (upper or lower).
Adults have 32 teeth differentiated in 16-16 between the two jaws and are categorized in to 4 types i.e, incisors,canines,molar,premolar..This includes the wisdom teeth which are simply a third set of molars. It is possible to be born with less than 32 teeth or more than 32 teeth. If a person has had all four of their wisdom teeth removed, they will have 28 teeth. If they have also had braces, which oftentimes requires the removal of the four first bicuspid teeth, they will function in life with 24 teeth. Children have 20 teeth, once they all come in of course. By the age of 2 years most children have all of their primary (baby) teeth.20http://en.wikipedia.org/wiki/Teeth#Anatomy Humans usually have 32 permanent teeth (and 20 primary teeth (also called deciduous, baby, or milk teeth))
