So they can eat plants, but not animals.
If by round, you mean 'not sharp' that would be most of the vegetarian animals, such as: cows, deer and koalas. They have wider flatter teeth in order to chew plants, grass, leaves and vegetation, kind of like the molars humans have in the back of the mouth.
The sharpness or dullness of an animals teeth determines what type of food it eats. Animals that are herbivores have the dullest teeth since they don't need sharp teeth to cut through meat.
Pigs have rounded teeth that are adapted to their diet of plant material and soft meats. Pigs are not carnivores so they don't need sharp teeth.
The perch's teeth adapted to their function of eating harder prey than what their ancestors ate. This means that a perch has relatively hard and pointy teeth.
They are adapted by the way they are structured and the way they are shaped like a worm and the teeth they have
Animals that have broad and sharp teeth in the front, followed by broad flat teeth inside are likely herbivores. Some examples of such animals include cows, horses, and elephants. The sharp front teeth help to cut and tear vegetation, while the flat back teeth are used for grinding and chewing food.

the teeth of carnivores were sharp so that they could cut through meat and bone easily. and since herbivores didn't need that their teeth were flat

Omnivores typically have a combination of sharp teeth for tearing and flat teeth for grinding. This allows them to consume both meat and plants efficiently. Their teeth are adapted to handle a diverse diet that includes both animal and plant materials.
In their incisors, yes. They do have upper molars though, just like a domestic cow does.
Sharp teeth for carnivores and broad and flat molars for the herbivores. For the omnivores, well, either of those two.
flat teeth
Molars and the bath teeth that crush and grind food!
FLAT
Because they are carnivores. Sharp teeth are needed to tear flesh. Flat, broad teeth are needed to crush the rigid cell walls and fibers of plants.
