Teeth and its type
Explanation:
A normal adult mouth has 32 teeth.The type of teeth are classified as follows:
*Incisors(8 total):The middle most four teeth on the upper and lower jaws.
*Canines(4 total):The pointed teeth just outside the incisors.
*Premolars(8 total):Teeth between the canines and molars.
Molars(8 total):Flat teeth in the rear of the mouth,best at grinding food.
*Wisdom teeth or third molars(4 total):These teeth erupt at around age 18,but are often surgically removed to prevent displacements of other teeth.
Listed below are the form and functions of types of human teeth:
Incisors:Incisors are present at the front of the mouth.These teeth have sharp edges and are adapted for cutting food into small,chewable pieces.Human have eight incisors,four incisors in the upper jaw and four in the lower jaw.
Canines:Canines are also called cuspids.They are situated at the corners of the dental arches.They are characteristically sharp,elongated and pointy surface.Their primary function is to grip and tear food(tough food such as meat). Humans have four canines,two in the upper jaw and two in the lower jaw.
Premolars:Premolars are also called bicuspids and are located behind the canines.These teeth have a flat surface with ridges,which is adapted for crushing and grinding food into smaller portions.Humans have eight premolars,tow on each side of the jaws.
Molars:Molars are the largest and strongest teeth.It has a large and flat biting surface,which is well-adapted for grinding foods.Humans have 12 molars ,six in each jaw.Four of those are wisdom teeth which is also called third molar,which come in between the ages of 17 to 25.
Wisdom teeth:Wisdom teeth also referred to as the third set of molars.They are vestigial and final set of molars.This set of teeth appear between the age of 17 to 25.Most of them remove their wisdom teeth and this mainly because of the poor alignment and partial eruption,which results in the bacterial infectious diseases,pain,swelling and stiffness of the jaw.
Therefore,there are 32 teeth in the mouth and are classified into five types.
