Reason #4 an airway dentist can help you!

Dark Circles Under Eyes

Dark rings under the eyes are not just a sign of poor sleep. They are an indication that the upper jaw's development and growth is not what it should be. This is technically called venous pooling. If you see this in a child, sleep and brain development are usually a concern.

Happy Nutrition Fact Friday!

It’s that time of year when cinnamon takes center stage. From warm drinks to baked treats, this spice doesn’t just taste like fall, it’s packed with health benefits too!

Did you know, ancient physicians used cinnamon as a natural remedy for respiratory ailments such as coughs and colds. Its warming properties and natural antimicrobial compounds made it a valued treatment in traditional medicine across Egypt, China, and Greece. Today, modern research continues to explore cinnamon’s immune-supporting and anti-inflammatory benefits.

Swipe to see more of why a sprinkle of cinnamon can go a long way!🍁

Reason #3 an airway dentist can help you!

Scalloped tongue

When there is not enough room in the mouth for the tongue, it will push against the teeth and form indentations on the side of the tongue. This is called a scalloped tongue. However, it is not the tongue that’s a problem. It’s the house it lives in.

If the dog is too big for the dog house, what do you do? Get a larger dog house. In most cases – both children and adults – it is possible to expand the jaw to create larger jaws, healthier bodies and brighter smiles.

A scalloped tongue in adults is 70% indicative of sleep apnea.
