Teeth and Their Importance
Teeth are vital components of the human and other living beings' mouths and digestive systems. They play a crucial role in the process of nutrition and digestion by helping to break down food and reduce its size for easier swallowing and digestion.
Types of Teeth and Their Functions
Human teeth are composed of different types, and each type serves a specific function.
Structure of a Tooth and Its Main Components
A tooth is composed of several main parts. The outermost layer is the enamel, which is the hard and strong layer that covers the outer surface of the tooth.
The effect of plaque on the teeth
The presence of plaque on the teeth leads to the loss of minerals in the enamel layer and its erosion, after which holes begin to form, and then acids and bacteria move to the second layer of the tooth (dentin).
Complete tooth decay
When damage from bacteria and acids reaches the third layer of the tooth (pulp), which contains blood vessels and nerves, then symptoms begin, such as pain when biting on the tooth or sensitivity to hot or cold foods. The body begins to resist these bacteria by forming white cells that form the abscess.
Back teeth (molars)
More susceptible to decay due to exposure to foods for a long time; This makes it more susceptible to plaque formation compared to front teeth, such as canines and incisors. Its location also makes it more difficult to clean with brushes and other care methods
Dry mouth
It is a condition characterized by decreased saliva secretion, and decreased saliva secretion in the mouth increases the risk of tooth decay. Because saliva contains antibodies that resist acids and bacteria
