Explain teeth with help of diagram
Answers
Answer:
Teeth are made up of different layers — enamel, dentin, pulp, and cementum. Enamel, which is the hardest substance in the body, is on the outside of the tooth. The second layer is dentin, which is softer than enamel, and the deepest layer inside the tooth is pulp, which consists of nerves and blood vessels.
THE DIFFERENT TYPES OF TEETH AND THEIR PURPOSE
As mentioned above, there are five types of teeth in your mouth and each of them performs a specific and unique duty. These different types of teeth are:
Incisors: The top four and bottom four front teeth are called incisors. These
are usually the teeth you use to initially bite your food into portions that can be easily chewed.
Canines: The four pointed teeth on either side of your incisors are called canines. These are the sharpest teeth in your mouth and are used for ripping and tearing foods.
Premolars: Premolars, also known as bicuspids, are the next teeth in the series. These are used for chewing and grinding your food and you have four on either side of your mouth.
Molars: Your primary molars are slightly bigger than your bicuspids but serve a similar purpose.
Third Molars: Commonly known as wisdom teeth, your third molars are often removed, or extracted when they erupt in your late teens or early twenties.
