Deciduous teeth, also known as baby or primary teeth, are the first set of teeth that humans and other mammals develop. They start to come in (erupt) when a baby is about 6 months old. There are 20 deciduous teeth in total: 10 in the upper jaw and 10 in the lower. These include:

1. Incisors: These are the front teeth used for biting and cutting. There are four upper and four lower incisors.

2. Canines: These are the sharp, pointed teeth on either side of the incisors. They are used for tearing food. There are two upper and two lower canines.

3. Molars: These are the larger teeth at the back of the mouth used for grinding food. There are four upper and four lower molars.

Permanent teeth, also known as adult or secondary teeth, replace the deciduous teeth and are intended to last a lifetime. Most people have 32 permanent teeth: 16 in the upper jaw and 16 in the lower. These include:

1. Incisors: Like the deciduous teeth, these are the front teeth used for biting and cutting. There are four upper and four lower incisors.

2. Canines: These are the sharp, pointed teeth on either side of the incisors. They are used for tearing food. There are two upper and two lower canines.

3. Premolars: These are also known as bicuspids. They are used for crushing and grinding food. There are four upper and four lower premolars.

4. Molars: These are the larger teeth at the back of the mouth used for grinding food. There are six upper and six lower molars.

5. Wisdom Teeth: These are a third set of molars that usually come in during late adolescence or early adulthood. Not everyone develops wisdom teeth, and for those who do, they often need to be removed due to lack of space in the mouth.
