Occlusion is a term that is used to refer to the alignment of your teeth. Ideally, your teeth should fit easily within your mouth without any crowding or spacing. In addition, none of your teeth should be rotated or twisted. The teeth of your upper jaw should slightly overlap the teeth of your lower jaw so that the points of your molars fit into the groves of the opposite molar. Deviations from ideal occlusion are known as malocclusion. If the teeth are misaligned, they will not be able to perform vital functions and may cause dental and medical problems.
