Can you sleep with a night guard in?

Night guards are prescribed for nocturnal bruxism, a condition where patients grind or clench during sleep without conscious awareness. The appliance sits between the arches and absorbs occlusal load before it reaches enamel and the periodontal ligament. Lab-fabricated hard acrylic guards, processed over a stone model or milled from a PMMA puck, offer a precise fit that over-the-counter thermoplastic options cannot replicate. That precision is what makes overnight wear tolerable and therapeutically effective.

For general dentists prescribing night guards, the clinical outcome depends almost entirely on fit quality. A guard that rocks, creates a posterior open bite, or irritates soft tissue will be abandoned by the patient inside a month. Turnaround time matters here too: a 5-7 business day fabrication cycle keeps the patient compliant because the appliance arrives before the motivation fades. Labs that deliver a verified occlusal record, articulated correctly, produce guards patients actually wear.

From a lab workflow standpoint, night guards fall under the broader sleep and occlusal appliance category alongside snore guards and repositioning splints. Dentists who order consistently across that category benefit from a single lab relationship where the technician knows their preferred design, bite registration protocol, and delivery preferences. That consistency reduces remakes and the chair-time cost of fitting appointments that run long.
