Teeth are an essential part of the human body, playing a crucial role in digestion, speech, and overall oral health. Each type of tooth has a specific function, structure, and name. Understanding the names of teeth, their functions, and their importance can help maintain good dental health and prevent oral diseases. This article explores the names of teeth, their classifications, significance, and tips for maintaining oral hygiene.
Classification of Human Teeth
Humans have two sets of teeth in their lifetime:
- Primary (Deciduous) Teeth – Also known as baby teeth, they start to emerge at around six months and are eventually replaced by permanent teeth.
- Permanent Teeth – These are adult teeth that replace baby teeth and last a lifetime with proper care.
Below is a table categorizing the different types of teeth along with their functions:
| Type of Teeth | Number in Adults | Number in Children | Function |
|---|---|---|---|
| Incisors | 8 | 8 | Cutting and biting food |
| Canines | 4 | 4 | Tearing and ripping food |
| Premolars (Bicuspids) | 8 | 0 | Grinding and crushing food |
| Molars | 12 (including wisdom teeth) | 8 | Chewing and grinding food |
Names and Functions of Different Teeth
1. Incisors
- Location: Front of the mouth (four on the top, four on the bottom)
- Shape: Flat, thin, and sharp
- Function: Used for cutting and biting food

2. Canines (Cuspids)
- Location: One on each side of the incisors (top and bottom)
- Shape: Sharp and pointed

- Interesting Fact: Canines are the longest teeth in the human mouth.
3. Premolars (Bicuspids)
- Location: Behind the canines (two on each side, top and bottom)

4. Molars
- Location: Back of the mouth (three on each side, top and bottom)
- Shape: Large and flat
- Function: Used for chewing and grinding food into digestible pieces
- Interesting Fact: The third molars, also known as wisdom teeth, often require removal due to lack of space in the jaw.
Importance of Teeth in Daily Life
