Orofacial myofunctional disorders (OMDs) encompass a range of issues that can arise when the muscles of the face and mouth are not functioning properly. These disorders can lead to a variety of problems, including: Tongue Thrust: This occurs when the tongue pushes against the teeth during swallowing, leading to dental issues such as open bites and misaligned teeth. Abnormal Swallowing Patterns: Incorrect swallowing can affect the development of facial muscles and lead to dental problems. Speech Difficulties: Improper muscle function can result in articulation problems and speech impediments. Mouth Breathing: This can be caused by airway obstructions or habits such as thumb-sucking, leading to improper jaw positioning and other complications.
