Cavities extracted without filling may affect the occlusion, misalignment, and aesthetics. 1. Bite: After tooth decay is extracted, the teeth on both sides may be tilted in a defective way, and the upper and lower teeth may elongate on the opposite side due to the lack of occlusion, even affecting the mucous membranes of the teeth, which will lead to occlusal disorders of the teeth. 2. Misalignment of teeth: After a cavity is extracted and not filled in time, the gap will cause the teeth on both sides to tilt towards the center, resulting in misalignment of teeth. Missing teeth may also lead to food impaction, resulting in gum infection. 3. Affecting aesthetics: Cavities extracted without filling may have a certain impact on the patient’s appearance, especially the incisors, which has a certain impact on the patient’s mental health. If the patient after tooth decay extraction, should go to the hospital in time for tooth filling repair, can be installed through the movable denture or fixed denture and dental implants for tooth filling.
