A bad bite can affect the shape of the face, and most of them have a greater impact on the shape of the face and even on health. I have seen many celebrities on the Internet before and after the orthodontic treatment, the face shape will change, sometimes change the teeth, the whole face shape will change, the whole line looks more smooth, comfortable and harmonious. The bite of the teeth is closely related to the shape of the face, so a misaligned bite will definitely affect the shape of the face. If there is a bite misalignment, such as the often said partial (teeth together) situation, usually this type of people will show a crooked face. When walking on the road, no one may notice the crooked face, but people may think that the patient’s face looks strange. People with crooked faces usually not only look uncomfortable and feel weird, but they themselves are also deeply disturbed by occlusal problems, as patients often have occlusal interference in their bite, even to the joints, often referred to as the temporomandibular joints. Such people often have a combination of chronic pain in the temporomandibular joint area, headaches and discomfort. Therefore, in addition to the effect of malocclusion on the shape of the face, it can have a greater impact on the health of the whole body. Therefore, it is recommended that once a malocclusion occurs, we should seek medical attention as much as possible.
