The primary function of premolars is the crushing of foods before they are transferred to the molars for the final grinding. Humans have eight premolars, two on either side of the mouth and in the upper and lower jaw, respectively. Premolars: They are also called Bicuspids and are found adjacent to the canines, towards the back of the mouth.The primordial function of canines is to rip and tear tough foods like meat. Canines : Also called Cuspids, canines are located next to the incisors, with two on the top of the mouth and two on the bottom.The primary function of incisors is to aid the mastication process – eating and biting food into chewable pieces and moving them inwards. They are flat and broad and have a shovel-like structure. The shape of incisors is like small chisels. There exist four incisors in the upper human jaw and four on the lower. Incisors: Alternately known as ‘Cutting Teeth,’ incisors are located at the center of the dental arch – the front part of the mouth.Likewise, adult humans have all their permanent teeth in place by the age of 21. It is essential to mention that the first milk teeth of babies erupt when they are between the age of 6 to 12 months. On the contrary, children merely have 20 teeth which we term as milk teeth or primary teeth. To begin with, human adults have 32 teeth which are known as permanent teeth or secondary teeth. Now that we have talked about the fundamentals of human teeth, let us examine its four types, their shape, and function. The main reason why humans have four different kinds of teeth is that as a species, humans are omnivorous and hence require different types of teeth to handle both plant-based items and meat. The shape and morphology of the different teeth types depend on their function. Another interesting facet of human teeth is that they are of four varied types – each having a typical appearance and job. In addition, the teeth coupled with the tongue also assist us to speak more fluently. The purpose of teeth is to chew foods and facilitate better consumption. They are the strongest parts of the human body and are composed of proteins and minerals like collagen and calcium. We all know that teeth are an integral part of human anatomy.
