Orthodontics is the branch of dentistry that specializes in the diagnosis, prevention and treatment of dental and facial irregularities. More than 4 million people in the United States and Canada are in the care of an orthodontist and are looking forward to beautiful, healthy smiles. Orthodontics can boost a person's self-image as the teeth, jaws and lips become properly aligned. But an attractive smile is just one of the benefits. Proper orthodontic treatment can prevent tooth decay, gum disease, bone destruction, and chewing and digestive disorders. How early can a child seek orthodontic treatment? In some cases, children as young as 3 or 4 years of age. Many orthodontic problems are easier to correct if detected early rather than waiting until jaw growth has slowed. Early treatment may enable a patient to avoid surgery or other more serious corrections later in life. Are you ever too old to get braces? No. Healthy teeth can be moved at any age, so an orthodontist can improve the smile of practically anyone. It's not uncommon for an orthodontist to treat patients in their 50's, 60's, and older! The most common disorders occurring for different age groups are included in this section.
