C. Premolars
D. Molars

Explanation

**Step-by-Step Solution:**

1. **Understanding the Types of Teeth**: First, we need to identify the different types of teeth in humans. The main types are incisors, canines, premolars, and molars.

2. **Identifying the Function of Each Type**:
- **Incisors**: These are the front teeth used for cutting food.
- **Canines**: These are pointed teeth next to incisors, used for tearing food.
- **Premolars**: These are located next to canines and are used for crushing and grinding food.
- **Molars**: These are the large teeth at the back of the mouth, also used for grinding food.

3. **Focusing on Grinding Teeth**: Since the question specifically asks for teeth used for grinding, we need to focus on premolars and molars.

4. **Identifying Their Location**: Both premolars and molars are present on each side of both jaws.
- **Premolars**: There are two premolars on each side of the upper jaw and two on each side of the lower jaw.
- **Molars**: There are three molars on each side of the upper jaw and three on each side of the lower jaw.

5. **Conclusion**: The teeth that are present on each side of both jaws and are used for grinding are the **premolars** and **molars**.

**Final Answer**: The teeth used for grinding, present on each side of both jaws, are the **premolars** and **molars**.
