At the International Academy of Biological Dentistry and Medicine, biological dentistry recognizes that oral development involves more than the teeth and jaws. The position of the tongue can also influence how the mouth functions and develops, particularly during childhood.
What Is Healthy Tongue Posture?
When the mouth is at rest, the tongue typically rests gently against the roof of the mouth, with the lips closed and breathing occurring through the nose. This position helps support normal oral function and works together with the muscles of the face and jaw.
When the tongue consistently rests low in the mouth or pushes against the teeth, it may affect the forces placed on developing oral structures. Over time, tongue posture can be one of several factors influencing tooth position, bite development, and jaw growth.
Breathing and Tongue Position
Tongue posture and breathing patterns are closely connected. Persistent mouth breathing may cause the tongue to rest lower in the mouth rather than against the palate. Nasal congestion, airway concerns, oral habits, and other factors may contribute to these patterns.
For growing children, identifying persistent mouth breathing or unusual tongue positioning early provides an opportunity for appropriate evaluation.
Looking at Oral Development as a Whole
Biological dentistry encourages practitioners to consider how the tongue, jaws, teeth, facial muscles, and airway work together. Rather than focusing exclusively on whether teeth appear straight, evaluating oral function can provide a more complete picture of development.
The International Academy of Biological Dentistry and Medicine is committed to advancing education about biological dentistry and whole-body health. Greater awareness of tongue posture and oral function can help practitioners and families support healthy development from an early age.
