Frequently Asked Questions
Is the Oral-B nighttime dental guard good for teeth grinding?
It's a decent beginner option. It's the easiest to mold (5/5 moldability score in our test), but its 12.5% thickness loss in 30 nights means it won't last more than a few months for moderate-to-heavy grinders.
How do I mold the Oral-B nighttime dental guard?
Boil water, remove from heat, wait 30 seconds, submerge the guard for 60 seconds, center it over your upper teeth and bite down firmly. It's one of the most forgiving boil-and-bite guards we've tested — very hard to mess up.
