We Test Night Guards With Digital Calipers

Independent, data-driven reviews for teeth grinding and bruxism. No fluff. Just thickness measurements, wear rates, and honest fit tests.

Most night guard reviews online are written by people who have never worn the product. We buy every guard with our own money, wear it for 30 consecutive nights, and measure exactly how much thickness it loses using a digital caliper.

📋 Our testing standard: 7 night guards wear-tested · 30 nights each · 3-point caliper measurements · thickness loss range: 2.7% – 32% · All products purchased with our own money. Full protocol →
