There is no best way to deal with large gaps in adult incisors, and you will need to choose between resin fillings, braces, and other methods of treatment depending on the specific situation. 1. Resin Filling: Resin filling is a method to improve the gap by using a resin close to the color of the teeth, which needs to be bonded into the gap, and can quickly improve the symptoms of large gaps in the incisors. 2. Braces: Most large gaps in the front teeth are most likely related to growth spurts, which can be fixed with braces. Braces can bring the teeth closer to the center to slowly reduce the gap, which is a more natural and healthy way to correct the gap without harming the teeth. A large gap between the incisors is likely to lead to the emergence of food congestion, if not treated in a timely manner, may also trigger gingivitis and other uncomfortable symptoms, so it is recommended to go to the regular hospital in a timely manner, according to the doctor’s advice to choose the appropriate treatment.
