Adult oral upper and lower jaws generally have a total of 28 to 32 permanent teeth and are arranged in a more orderly manner to form a stable dental occlusion. However, people often lose teeth in the mouth due to tooth decay, periodontal disease, trauma and other reasons in life. Sometimes people do not care about a missing tooth because they think it is a small matter. In fact, even a single missing tooth can cause a series of dental and dental problems, and the consequences are even worse if the tooth is not set for a long time. When a tooth is missing, it will lead to ① neighboring teeth tilting toward the gap ② neighboring teeth food embedding ③ neighboring teeth decay ④ opposing teeth elongation ⑤ bite curve change ⑥ future dental space is occupied by neighboring teeth and opposing teeth. Therefore, for the sake of dental health and dental stability, it is recommended to have a veneer as soon as possible after tooth loss.
