Jaw abnormalities refer to any irregularities in the structure or function of the jaw, which can affect chewing, speaking, and overall oral health. Common types include overbites, underbites, and crossbites, where the upper and lower teeth do not align properly. These conditions can result from genetic factors, developmental issues, or injuries. Treatment for jaw abnormalities often involves orthodontics, such as braces or aligners, to correct alignment. In more severe cases, surgical intervention may be necessary to realign the jaw. Regular dental check-ups can help identify these issues early, ensuring better outcomes for patients with jaw abnormalities.
