Malocclusion refers to a misalignment of the teeth and jaws, which can affect how the upper and lower teeth fit together when the mouth is closed. This condition can lead to various dental issues, including difficulty in chewing, speech problems, and increased wear on teeth. Malocclusion is often classified into different types, such as overbite, underbite, and crossbite, each indicating a specific alignment problem. Several factors can contribute to malocclusion, including genetics, thumb sucking, and early loss of baby teeth. Treatment options vary depending on the severity of the condition and may include orthodontic devices like braces or aligners. Addressing malocclusion is important for maintaining overall oral health and improving the function of the teeth and jaws.
