A normal adult will generally have 32 teeth, 16 on the top and 16 on the bottom. You can divide the teeth into 4 areas according to the top, bottom, left and right, and count the teeth from the incisors to the sides. For example, in the picture below, the marked “central incisor” can be called “lower left 1”, the marked “lateral incisor” can be called “lower left 2 “, and so on. In addition, there is another method, which is to add the orientation in front of the labeled tooth name, for example, the labeled “central incisor” can also be called “lower left central incisor”, the labeled “lateral incisor” can also be called “lower left lateral incisor”. can also be called “lower left lateral incisor”, and so on, so that you can call the name of your teeth more professionally. As shown in the picture.
