Buying Guide

Upper vs lower guard

Lower guards often feel less intrusive for jaw alignment, while upper guards can provide broader tooth coverage—choose based on comfort and dental advice

Hardness and thickness

Softer, thicker guards absorb more clenching force for soreness relief; harder, thinner trays prioritize durability and occlusion control

Custom fit matters

Custom-made or impression-based guards conform to your bite and reduce waking jaw soreness compared with generic, one-size options

Material and breathability

Medical-grade EVA or similar dental plastics resist wear and minimize bulk; check for designs that allow airway comfort and saliva flow

Maintenance and longevity

Choose guards that are easy to clean and resilient to daily use to maintain hygiene and consistent soreness relief over months
