What kind of teeth do bears have?
Bears are heterodonts, meaning they have different types of teeth: incisors, fangs, molars and premolars.
Bears use their teeth for a variety of tasks, but mainly to chew, grind and grind food to eat. They also use them to kill and catch things.
They have a total of 42 teeth:
- 12 cutters
- 4 Canines
- 16 premolars
- 10 molars
- The incisors are the front teeth used to cut food and tear the meat from prey.
The canines are the sharp, pointed teeth in the upper and lower jaw that carry prey when bears kill their food.
Premolars are flat teeth located behind the canine teeth and in front of the molars. They help in grinding food.
And finally, the molars are large, sharp back teeth that crush and grind food.

How many teeth do bears have?
Most bears have a total of 42 teeth: 12 incisors, 4 canines, 16 premolars and 10 molars.
Bears have very diverse teeth. They use their teeth to crush and break apart nuts, seeds and other plant foods. They also use them to tear the flesh of animals they have killed.
They will often bite into food at a 45 degree angle rather than the 90 degree that most carnivores do.
This is because the bears' saliva contains enzymes that help them digest plants better than other animals can manage on their own.
How do bear teeth work?
Bears' teeth serve different purposes. Like so many other omnivores, they also use teeth to eat, cut, grab, crush and grind food or other things.
As mentioned, bears have different types of teeth, each with its own purpose. Depending on their type and location, they serve different purposes.

Black bear cutters are straighter and less curved, and are more suitable for cutting vegetation.
Molars (Grinders)
Bears have molars on each side, three up and two down. These are wide and flat teeth.
Molars are the largest and most important teeth in a bear's mouth. They are used to grind food and are shaped differently depending on the type of bear.
Premolars
Bears have four premolars between each of their canines and molars. Bears have 16 premolars in all. They are used in cutting the foods in many parts and for grinding the food in smaller pieces. Bears usually have a gap between their premolars. This is called a diastema and is seen in many herbivores.
This gap is useful for catching stems or twigs.
