Science: Label the teeth | Worksheet | PrimaryLeap.co.uk - Free Printable

Let's solve the task step by step.

Task:

Label the teeth in the diagram using the words from the word bank:
Word Bank: premolar, canine, incisor, molar

Step 1: Understand the types of teeth

Humans have four main types of teeth:
1. Incisors – These are the front teeth used for cutting food.
2. Canines – These are the pointed teeth next to the incisors, used for tearing food.
3. Premolars – These are located behind the canines and are used for crushing and grinding food.
4. Molars – These are the large, flat teeth at the back of the mouth, used for grinding food.

Step 2: Identify the positions in the diagram

Looking at the diagram:

#### Upper Teeth (from front to back):
1. Front teeth – These are the incisors (they are flat and used for cutting).
2. Next to the incisors are the canines (pointed teeth).
3. Behind the canines are the premolars.
4. At the very back are the molars.

#### Lower Teeth (from front to back):
1. Front teeth – Again, these are incisors.
2. Next are the canines.
3. Then come the premolars.
4. At the back are the molars.

Note: The diagram shows two sets of each tooth type — upper and lower — but the labels are grouped with lines pointing to specific areas.

Step 3: Match the labels

We need to fill in the blanks based on the lines pointing to each group.

From the diagram:
- The top line points to the front upper teeth → Incisor
- The second line points to the upper pointed teeth → Canine
- The third line points to the upper teeth behind the canines → Premolar
- The fourth line points to the back upper teeth → Molar

Similarly for the lower teeth:
- The first line points to the front lower teeth → Incisor
- The second line points to the lower pointed teeth → Canine
- The third line points to the lower teeth behind the canines → Premolar
- The fourth line points to the back lower teeth → Molar

Final Answer:

Upper teeth:
1. Incisor
2. Canine
3. Premolar
4. Molar

Lower teeth:
1. Incisor
2. Canine
3. Premolar
4. Molar

✔ This completes the labeling correctly based on human dental anatomy.
