The teeth are formed in two different phases. Initially, the child will develop 20 teeth, payable from 6 years old, leading to the second phase of the formation of secondary teeth ‘or permanent teeth. Usually an adult will have 32 teeth, including molars burst delay the trial.
Each tooth takes time to appear and four categories of the teeth can be seen in a human mouth. These categories include the incisors, canines, premolars, molars and third molars. In a grown adult, there will be eight four incisors in each jaw teeth on the first floor. Second, two canine teeth protruding at the sides of the jaw and the total number of canines is four. Pre-molar teeth are closely following the canines and premolars have four each jaw arranged as two on both sides.
Therefore, the total number of pre-molar teeth is equal to eight. They include the molar tooth on both sides of the jaw, and in general, the total number of molar teeth is eight. Finally, there will be four third molars in the back of the jaw; one on each jaw is also the last teeth to erupt. The third molars are also known as wisdom teeth and some individuals who do not appear on the surface at all.
The food consumed by human beings varies in consistency and therefore requires certain actions before swallowing. These actions should mark the beginning of the digestive process and also called mechanical digestion. Teeth play an important role in the digestive process and the precise location of each tooth together with its shape and structure different way for food processing actions opens. Let’s see some of the actions performed by each type of teeth in the digestive process.
Incisors: The teeth are sharp and have a horizontal distance that has the potential to act as a knife. Therefore, these teeth will be used in order to take a bite of food relatively mild, but in some cases it will work equally well for consistency too hard.
Dog: As the name implies, it will appear like the teeth of a dog and will be remembered and done only for the purpose of ripping and tearing meat and other foods of the same consistency.
Molar tooth: All molars that appear in a human jaw would be made to grind and chew purpose and the transition from front to back would make it easier for the individual task, as it would be the last act committed by the teeth before swallowing It occurs.
Therefore, obtained bites of incisors and canines ripped from food particles will be crushed by the molars and chewing before swallowing.
