About Space

Dental arches rely on balanced pressure and structural space to maintain their shape. Jaw compression patterns can influence how space distributes across the arches.

Pressure Distribution
Matters

When jaw pressure is uneven, arches may experience uneven loading patterns. Balanced positioning may support more even pressure distribution across the dental arches.

“In December, I noticed my upper and lower arch expanded. My premolars were showing more when I smiled. My lower arch was rounding out to be more of a wide U shape.”

“I think it is visible that my upper palate became a little wider and the teeth are less inclined inwards, especially on the left side!”

“I have issues with jaw tension & subconscious clenching. My jaw muscles are barely tight at all now! I actually love the feeling of taking it out in the morning as it’s clear my whole structure is finding its way towards better alignment.”

“Where I once had crowding on the lower teeth, I now have a small gap! My right side is definitely inflating and my palate is growing. So excited.”

“My top front teeth are straight. A week off my Invisalign retainer would have meant overlapping before. With Reviv, they’re staying aligned. Something is different.”
