Types of Teeth Worksheet Solution and Explanation

#### 1. Label the teeth below.
The image shows a diagram of an open mouth with labeled parts A, B, C, and D. Here are the correct labels for each part:

- A: Incisors
- These are the front teeth used for biting and cutting food.

- B: Premolars (or Bicuspids)
- These are the teeth located between the canines and molars, used for tearing and crushing food.

- C: Canines
- These are the sharp, pointed teeth next to the incisors, used for tearing food.

- D: Molars
- These are the large, flat teeth at the back of the mouth, used for grinding and chewing food.

So, the answers are:
- A: Incisors
- B: Premolars
- C: Canines
- D: Molars

#### 2. Complete the ways the teeth A-D break down food. The first word is completed for you.

Each type of tooth has a specific function in breaking down food. Let’s fill in the blanks based on their functions:

- A: This tooth bites and cuts food.
- Incisors are primarily used for biting and cutting food into smaller pieces.

- B: This tooth tears and crushes food.
- Premolars (bicuspids) have a combination of sharp edges and flat surfaces, making them effective for tearing and crushing food.

- C: This tooth tears and pierces food.
- Canines are sharp and pointed, designed for tearing and piercing food.

- D: This tooth grinds and chews food.
- Molars have broad, flat surfaces that are ideal for grinding and chewing food into smaller, more manageable pieces.

So, the completed sentences are:
- A: This tooth bites and cuts food.
- B: This tooth tears and crushes food.
- C: This tooth tears and pierces food.
- D: This tooth grinds and chews food.

#### 3. Which type of tooth do you use to break down these types of food?

We need to match the types of food with the appropriate teeth based on their functions:

- a. Apples, broccoli, or mango:
- These foods are hard and require cutting and tearing.
- Answer: Incisors and Canines

- b. Chicken or beef:
- These foods are meaty and require tearing and chewing.
- Answer: Canines and Premolars/Molars

- c. Rice or nuts:
- These foods are small and require grinding and chewing.
- Answer: Molars

So, the answers are:
- a. Apples, broccoli, or mango: Incisors and Canines
- b. Chicken or beef: Canines and Premolars/Molars
- c. Rice or nuts: Molars

#### 4. How many types of teeth A-D does an adult have if they have all their permanent teeth?

An adult with all their permanent teeth has a total of 32 teeth, which are distributed as follows:

- Incisors (A): There are 8 incisors in total (4 in the upper jaw and 4 in the lower jaw).
- Premolars (B): There are 8 premolars in total (4 in the upper jaw and 4 in the lower jaw).
- Canines (C): There are 4 canines in total (2 in the upper jaw and 2 in the lower jaw).
- Molars (D): There are 12 molars in total (6 in the upper jaw and 6 in the lower jaw).

So, the answers are:
- No. of A in adult mouth: 8
- No. of B in adult mouth: 8
- No. of C in adult mouth: 4
- No. of D in adult mouth: 12
