Benefits of braces: 1, correct occlusion. Uneven teeth lead to uneven bite force, which not only causes tooth wear, but also makes teeth loose and fall off earlier. Orthodontics can make the tooth arrangement and occlusal relationship normal, which is good for teeth. 2. Conducive to periodontal cleaning and health maintenance. Orthodontic cleaning is convenient, and it can also prevent dental caries and periodontal disease. 3. Prepare for the restoration of missing teeth. People who have missing teeth but are unwilling or not suitable for dental implants can also close the gap of missing teeth through orthodontics to achieve beautiful results. People with loose teeth and gaps can concentrate the gaps in their teeth through orthodontics and insert teeth in the parts where the gaps are formed, which can also achieve the purpose of aesthetics. However, patients need to go to regular hospitals for correction in order to achieve perfect results.
