The resting position of the tongue plays a crucial role in the development of facial and dental structures, affecting overall oral health. When the tongue is correctly positioned, with the tip resting on the roof of the mouth and the rest gently touching the palate, it promotes proper tooth alignment and jaw growth. This optimal tongue position also maintains an open airway for breathing, preventing issues like snoring and sleep apnea. 

However, a low resting tongue position, often stemming from a failure to transition from a visceral swallowing pattern during breastfeeding, can lead to various problems.

Children exhibiting a low tongue position may experience malocclusion, improper jaw growth, and breathing difficulties. Mouth breathing becomes common, resulting in dry gums and teeth, leading to dental issues like caries. Additionally, a wrong tongue position in the lower jaw can contribute to progeny, where the lower jaw undergoes increased growth. 

This chain of events can trigger a vicious cycle, impacting breathing, tonsil size, and overall health. Sleep apnea may also manifest, disrupting proper rest and potentially causing irritability, lack of appetite, and concentration disorders in children.

Beyond oral health, a misaligned tongue can have systemic effects on the entire body. Children may adopt an incorrect head and neck position during sleep, leading to misalignment of vertebras. Hence, addressing tongue position disorders becomes crucial not just for oral health but for holistic well-being.
