In both sides of this line, we now have dental arch. In a traditional dental situation, there are 10 tooth in proper or left of the arch each in higher and decrease jaws in major tooth. So, in complete, there are 20 major tooth if no dental issues like trauma, lacking tooth (hypodontia), and different components exist.
