Orthodontics is a special field of dentistry that focuses on the prevention and correction of malposition of teeth and jaws. While a general dentist focuses primarily on cavities and gum disease, orthodontists promote healthy teeth by targeting issues like improper jaw alignment, crooked teeth, and crowded teeth. But creating a beautiful, straight smile isn’t all that orthodontists do. By treating some of the underlying orthodontic problems that lead to tooth decay and tooth loss, orthodontists also help their patients maintain healthy teeth and gums.
