More Information
Cusps are essential in the function of teeth for grinding and breaking down food. Different teeth have a different number of cusps, which are adapted to their specific function in the dental arch.
Tips
A common mistake is confusing premolars with having one cusp like canines. Always remember that premolars, unlike canines, are designed for a more complex chewing function and typically have two or more cusps.
