Which One Does My Child Need?
There is no one-size-fits-all solution. Our team evaluates each child’s breathing, oral function, posture, jaw growth, and sleep to make the best plan. Often, a combination of therapies and appliances—coordinated with your dentist, orthodontist, or ENT—is the most effective approach.
