Jaw deficiencies refer to conditions where the jaw does not develop properly, leading to misalignment or underdevelopment. This can affect both the upper jaw, known as the maxilla, and the lower jaw, called the mandible. Such deficiencies can result in difficulties with chewing, speaking, and even breathing, impacting overall quality of life. Common causes of jaw deficiencies include genetic factors, developmental issues, and certain medical conditions. Treatment options may involve orthodontics, such as braces, or surgical interventions to correct the alignment and improve function. Early diagnosis and intervention are crucial for effective management of these conditions.
