Lesson Content

The Mouth

The mouth is a vital part of the human body, essential for eating. It contains teeth, which break down food before digestion.

What are Teeth?

Teeth are hard structures in the mouth used for cutting, tearing, and grinding food.

Types of Teeth

Incisors and Canines

Incisors: Front teeth with sharp edges for cutting and slicing food. They also help bite into food and shape it for chewing.

Canines: pointed teeth next to incisors, used for tearing food and holding it firmly. They also assist in the chewing process.

Premolars and Molars

Premolars: Teeth behind canines with broader surfaces for crushing and grinding food. They break down food and assist in chewing.

Molars: Largest teeth at the back, with flat surfaces and ridges for grinding and crushing food. They are the final stage of chewing, preparing food for swallowing and aiding digestion.

Importance of Oral Hygiene

Good oral hygiene is essential for overall health. It prevents tooth decay and gum disease, which can lead to serious health problems.Regular brushing and flossing remove plaque, preventing cavities and gum disease. Good dental hygiene promotes overall health, keeps teeth strong, and boosts confidence.
