The Sentinel Promise: Perfect fit or we remake it free.
Why do some NFL players let mouthguards dangle—or skip them altogether? The NFL doesn’t require them, so you’ll see everything from lip shields to clear, retainer-style trays (looking at you, Mahomes). We break down what pros actually wear, what truly protects teeth, and how to choose the right guard for real-world players.
Can a retainer move teeth back after they’ve shifted? Learn the difference between passive retention and active orthodontic movement, when a snug retainer may be different from a poor fit, and when to contact an orthodontist.
Just finished dental work? The right night guard shields crowns, veneers, and implants, stabilizes your bite, and eases jaw tension. See timelines by procedure and which guard to choose.
Front-tooth soreness after wearing a night guard can come from excessive retention, uneven pressure, incomplete seating or an unrelated dental problem. Learn what may be happening and when the guard needs adjustment.
Some people notice more jaw pain when temperatures drop or the weather changes, but cold weather has not been proven to cause TMD or worsen symptoms for everyone. Here’s what research actually shows—and what may help when your jaw feels more sensitive in winter.
What makes one mouth guard more popular than another? We looked at recent Sentinel order data to see which custom night guard customers choose most often—and why the most popular option isn’t necessarily the right choice for everyone.
Grinding or clenching your teeth at night? A custom night guard can protect your smile, relieve jaw pain, and save you hundreds compared to the dentist. Discover costs, types, benefits, and how to order your guard online in this complete guide from Sentinel Mouthguards.
