Orthodontics is a specialized branch of dentistry that focuses on diagnosing, preventing, and correcting irregularities in the alignment of teeth and jaws. It involves the use of braces, aligners, and other appliances to gradually move teeth into their proper position, improving bite function, facial aesthetics, and overall oral health. Orthodontics is not only about creating a straighter smile but also about ensuring proper jaw alignment to prevent issues like uneven tooth wear, speech difficulties, and chewing problems.
