Because there are many reasons for the enlargement of the gap, it is recommended to go to the hospital for an oral examination to see what the cause is, and to treat the symptoms. For simple children’s milk teeth gap can not care, but rather conducive to the replacement of new teeth. If the permanent teeth grow out of the gap, but the gap is not very large, you can temporarily observe, because the child is still in the stage of growth and development, children’s teeth gap may be temporary, the gap will be adjusted to normal. If the gap between the permanent teeth at the time of eruption is obviously large, it is recommended that the hospital take X-rays and other checks. For adults with large gaps between their teeth, it is not possible to directly fill them with materials, but requires a doctor to analyze the cause of the gap. If the gap is caused by deformity of tooth development during the process of tooth development and formation, or due to tooth loss, it can be improved by resin filling, or artificial restoration. When the above two methods still fail to achieve the desired results, a joint solution with implants, orthodontics, periodontics, or even orthognathic surgery is needed. If the gap is caused by periodontal disease, it is necessary to actively treat the periodontal disease, depending on the severity of the periodontal disease, and the size of the gap to determine whether restorations, periodontal surgery, orthodontic treatment to improve the size of the gap.
