An adult human has 32 teeth, which are essential for biting, chewing, and grinding food. These teeth are divided into four main types: incisors, canines, premolars, and molars.
Incisors are the teeth at the front of the mouth and are used for biting and cutting food. Adults have eight incisors, four on the top and four on the bottom. Canines, also known as cuspids, are sharp teeth located next to the incisors and are used for tearing food. Adults have four canines, two on the top and two on the bottom.
Premolars, also known as bicuspids, are located behind the canines and are used for grinding and crushing food. Adults have eight premolars, four on the top and four on the bottom. Molars are large, flat teeth located at the back of the mouth and are also used for grinding and crushing food. Adults have 12 molars, six on the top and six on the bottom.
Most adults have a full set of teeth by the time they are about 13 years old. However, some people may have more or fewer teeth due to genetics or other factors. Some people may also lose teeth due to injury, decay, or other conditions, and may need to have them replaced with dentures or dental implants.
Having a full set of healthy teeth is important for many aspects of daily life, including speaking, smiling, and eating. It is important to take good care of your teeth by brushing and flossing regularly and visiting the dentist for regular check-ups and cleanings. By maintaining good oral hygiene, you can help to ensure that you have a healthy set of teeth for many years to come.

The primary teeth include the following
- 8 incisors: These are the teeth at the front of the mouth that are used for biting and cutting food.
- 4 canines: These are the sharp teeth that are located next to the incisors and are used for tearing food.
- 8 molars: These are the large, flat teeth located at the back of the mouth and are used for grinding and crushing food.
As the child grows, the primary teeth will eventually be replaced by a full set of 32 permanent teeth. This process begins around the age of six when the first permanent molars emerge. The permanent teeth continue to emerge until the age of about 21 when the third molars (also known as wisdom teeth) are typically fully developed.
