#malocclusion, #orthodontics, #orthodontic treatment, #open bite, #deep bite, #anterior crossbite, #clear aligners, #brackets, #tooth alignment
Malocclusion is a condition in which the upper and lower teeth do not fit together correctly. When the teeth fit together well, it is easier to chew food effectively, speak clearly, and maintain a natural appearance. Leaving malocclusion untreated may reduce chewing efficiency and make tooth decay and gum disease more likely, so an accurate diagnosis and treatment at an appropriate time are important. Please consult an orthodontic specialist to decide whether and when to begin orthodontic treatment.2026-06-26
