If you don't pay attention to oral hygiene at ordinary times, it is also prone to gingivitis and gingival atrophy. The best correction age is 12 years old, which can get very good results. But he is an adult, because he was born without teeth or with large bone mass, resulting in sparse teeth and large gaps. It is unlikely to take orthodontics to bridge the gap, and the effect is minimal. You can also use veneers to repair front incisors, which looks beautiful. Posterior teeth can be flossed frequently to avoid the accumulation of dental caries and soft dirt. Porcelain bridge can also be used to repair teeth, but porcelain bridge is harmful to teeth and needs to remove enamel with a thickness of about 2 mm So what method is suitable for you depends on your age and dental condition.
