An adult human typically has 32 teeth, assuming all their wisdom teeth have come in and none have been removed. These 32 teeth are broken down into four categories:
- Incisors (8): The sharp front teeth for biting.
- Canines (4): Pointed teeth on either side of the incisors for tearing.
- Premolars (8): Located between the canine and molars, used for tearing and grinding.
- Molars (12): The broad teeth at the back of the mouth for grinding food. This includes the four wisdom teeth.
It's important to note that some adults may have fewer than 32 teeth due to wisdom teeth removal or other dental procedures.
