Frequently Asked Questions
Are online custom night guards as good as dentist ones?
In most cases, yes. D2C brands like Pro Teeth Guard and JS Dental Lab use the same FDA-cleared materials and dental lab processes as dentists, at 60–80% less cost. Our thickness-loss data confirmed both performed excellently over 30 nights.
How do at-home impression kits work?
Each brand ships you putty-based impression trays. You bite down for 2–3 minutes, mail the trays back, and receive your custom guard within 1–2 weeks. Pro Teeth Guard and JS Dental Lab both had accurate, comfortable final fits in our tests.
