As a dental hygienist in a pediatric dental office and having looked at thousands of little mouths, I would like to share a few facts. The letter "s" would identify the lower right first molar. Baby teeth are identified using letters a-t and adult teeth are numbered 1-32. The upper right second molar is a, first molar b, canine or cuspid c, lateral d, right central e, left central f, left lateral g, canine or cuspid h, first molar i, second molar j, lower left second molar k, lower left first molar l, cuspid or canine m, lower left lateral n, lower left central o, lower right central p, lower right lateral q, canine or cuspid r, lower right first molar s, lower right second molar t. I did notice in the picture of her crying with Lee holding her, wearing the Ohio State jersey, it looked as though her bottom cuspids were not in yet. Also from her swim suit picture smile the tooth spacing is different than the last known picture with her great grandpa. Lately it has been noticed that children are missing the upper lateral teeth. They just aren't forming. I will have to take a closer look at some of the more recent pictures that we know of. In my opinion a lot of the pictures that are out there are when Caylee was younger. Most of her adult teeth would just be tooth buds growing in the bone. But girls sometimes have tooth development faster than boys and little girls have lost the bottom two centrals at 4 years old although rare. Caylee was not yet 3 and 3 is the age that we start cleaning children's teeth. Most 3 year olds do have 20 teeth however there are exceptions. Some have congenitally missing molars or molars that are slower to develop than the rest of the teeth. There are so many possibilities on why the numbers 18 and 20 are stated.
