Human teeth are made up of two primary parts: the crown and the root. The crown is the portion of the tooth above the gums while the root is the part that anchors the tooth to the bone. Human teeth also compose of enamel and dentine that makes the teeth harder and less prone to tooth decay. Different mammals have very similar teeth. Due to teeth variation because of different food that different mammals eat, pig teeth can be a very good model for studying development of human teeth because they are mammalian omnivores. Like humans, pigs are diphyodant or develop and erupt two different generations of teeth in their mouths. Pig and human teeth also have outer coating of enamel, which is the hardest tissue in the human body. Dental Erosion Dental erosion is the gradual loss of normally hard surface of the tooth due to chemical and not the bacterial, processes. Erosion shows up hallow parts of the teeth and a general wearing away of the surface of the tooth. This can expose dentin underneath the enamel. Because…show more content…
