Sometimes i see pictures with open mouthes and see like 3 premolars or only molars... so maybe some people eill find this usefull, its not a very complete study though. but still.
central incisor, bigger than lateral, a bit tipped to the centre.
lateral a bit more tipped to the center than central incisor (sometimes people have this one tipped the othr way though),
canine is even more tipped. from the front you can see its curve surface,
then theres two premolars (bicuspids) or one... many times people have just one since sometimes they get one removed for orthodontics
then there are three molars in decreasing sizes. (did not draw the third since many people get them extracted)
the central incisor is slightly more narrow than the lateral, and the lateral has a little slope in its bitting edge.
canines are smaller thn upper ones and have a tipping to the centre.
then 2 premolar and three molars each one of them more tipped to the centre.
all of the inferior teeth are covered by upper ones
there a lot more things about teeth positions, sizes and shapes, but this is the basic to do a very decent set of teeth
