Buying Guide

Choose the right material

Hard, soft, and hybrid materials distribute bite forces differently—hard guards (1–2mm) often resist wear while soft 3mm options can cushion muscle strain more effectively

Upper vs lower guard fit

Upper guards are commonly recommended for coverage and stability; lower guards can be thinner and more comfortable for some wearers—pick the jaw position that suits your bite and comfort

Prioritize custom fit

Custom dental night guards made from in-home impressions provide a closer fit than boil-and-bite models, improving comfort and reducing jaw clenching that causes soreness

Consider guard thickness

Thickness (1mm to 3mm) affects cushioning and jaw posture—thinner hard guards offer durability, while thicker soft or hybrid guards provide greater shock absorption for sore muscles

Factor in value and ratings

Compare brands with consistent high user ratings and transparent product types—look for options that balance quality materials and positive reviews to maximize soreness reduction
