A custom sleep appliance needs more than a brief check that it fits over the teeth. The delivery appointment establishes how it seats, how securely it stays in place, whether the starting position is comfortable, and whether you can insert, remove, and care for it confidently. It also creates a baseline for later reviews of tooth pressure, jaw symptoms, and bite changes.
The fitting follows the medical and dental suitability decisions made earlier in the treatment pathway. It does not replace the diagnosis of sleep apnea or confirm that treatment is already effective. After delivery, adjustment and follow-up are usually needed, with objective assessment through the clinician managing the sleep condition. Before you leave, you should understand the starting instructions, what to do if the appliance causes a problem, and which appointment comes next.
