Eating on one side for a long time will cause unbalanced development of jaw joints on both sides during the adolescent development period. Eating on one side for a long time after adulthood will not cause enlargement of the dentition, but it can make the chewing muscles thicker, which may result in misalignment of the jaws, large and small faces, gingivitis and other conditions. 1. Malocclusion: As the other side of the teeth is not chewing for a long time, the center line of the lower front teeth will be tilted to the other side, which will cause the back teeth to appear edge-to-edge, tip-to-tip malocclusion. 2. Large and small face: the other side of the teeth that do not chew for a long time will lack exercise, resulting in poor development of facial tissues, shrinkage and uneven development, with one side of the face being large and the other side being small. 3. Gingivitis: the other side of the teeth due to long-term waste, may accumulate a lot of tartar and tartar between the teeth, prone to dental caries and thus triggering gingivitis. If you eat on one side for a long time, it is recommended that you chew on both sides when eating, and once you have symptoms, it is recommended that you go to the hospital in time for examination and standardized treatment under the guidance of the doctor.
