Frequently Asked Questions
What is the most durable boil and bite night guard?
Based on our 30-night caliper tests, The Doctor's NightGuard Advanced Comfort had the lowest thickness loss at just 4.5%, significantly outperforming the DenTek (8.3%) and Oral-B (12.5%).
How do I boil and bite a night guard correctly?
Bring water to a boil, remove from heat and wait 30 seconds, then submerge the guard for the exact time on the packaging (usually 30–60 seconds). Bite down firmly and hold for 30–60 seconds. Poor technique is the main cause of a bad fit.
