The Anatomy of Your Teeth: A Comprehensive Guide - Part 2

Types of Teeth and Their Functions

Humans have four different types of teeth, each designed for specific functions:

1. Incisors

Overview: Incisors are the sharp, chisel-shaped front teeth (four upper and four lower).

Function: They are primarily used for cutting food into manageable pieces.

Interesting Fact: Incisors are often the first teeth to appear in babies, usually around six months of age.

2. Canines

Overview: Canines are the pointed teeth located next to the incisors (two upper and two lower).

Function: They are used for tearing and grasping food.

Interesting Fact: Canines are the longest teeth in the mouth, and their roots go deeper into the bone, providing stability.

3. Premolars

Overview: Premolars, also known as bicuspids, are located behind the canines (four upper and four lower).

Function: They have a flat surface with ridges for crushing and grinding food.

Interesting Fact: Adults typically have eight premolars, which replace the primary molars that children have.

4. Molars

Overview: Molars are the large, flat teeth at the back of the mouth (six upper and six lower, including wisdom teeth).

Function: They are used for grinding and chewing food, breaking it down into smaller, digestible pieces.

Interesting Fact: Molars are the strongest teeth, designed to withstand the heavy forces of chewing.
