Adults have 12 molars, 4 canine teeth (2 upper and 2 lower), and 4 incisors in total. Adult teeth usually refer to permanent teeth, which follow a specific arrangement. In the middle are the incisors—four in total (two upper and two lower)—whose main function is to cut food for easier chewing. Adjacent to the incisors are the canines, four in total, which help further tear or shear large pieces of food.

Adult teeth usually refer to permanent teeth, which follow a specific arrangement. In the front center are the incisors—four in total (two upper and two lower)—whose main function is to cut food for easier chewing. Next to them are the canines, four in total, which help further shear large pieces of food into smaller portions. At the back of the mouth are the molars, totaling 12, which grind food thoroughly, aiding digestion and nutrient absorption in the gastrointestinal tract. Additionally, around the age of 18, adults may develop wisdom teeth, though the number varies; typically, there are between 4 and 8.
It is recommended to maintain good dental hygiene by brushing teeth morning and night to reduce food debris accumulation and prevent cavities. Using an appropriate toothpaste can also promote dental health. When chewing food, it's advisable to alternate between both sides of the mouth.
