Custom night guards are supposed to fit better than the boil-and-bite drugstore versions, so I looked at Teeth Night Guard Lab's Soft Flexible 2mm Slim Fit guard (item SOFTSLIM) to see if that holds up.
This guard is manufactured by Sparkling White Smiles Dental Lab, made in the USA, and free of BPA, latex, and phthalates — the same manufacturing standard as a guard fitted at a dentist's office, just ordered direct instead.
The 2mm slim profile is designed to be thin enough for all-night comfort while still absorbing clenching and grinding forces — you send in an impression kit, and the lab stores your mold for easy reorders later.
This model currently holds 704 reviews, and Teeth Night Guard Lab has specialized in custom grinding guards for over 20 years. It's also HSA/FSA eligible, which effectively lowers the out-of-pocket cost for a lot of buyers, and ships free.
