The Sentinel Promise: Perfect fit or we remake it free.
Daytime clenching causes jaw pain and tooth wear. Here’s why the best mouth guard isn’t the thickest—it’s the best-fitting. Learn how Sentinel’s No-Show Daytime Guard helps you relax your jaw in total comfort.
Standard mouth guards protect your teeth — not your cheeks. Sentinel’s dual-arch Tongue & Cheek Biting Relief Guards cover both the upper and lower teeth, completely eliminating your ability to bite or catch your cheek while you sleep.
It often starts with a small accident — a quick bite that leaves a sore spot you can’t stop hitting. Over time, that simple injury can turn into a frustrating cycle of irritation made worse by stress or habit. Learn how to break the loop, calm your mouth, and heal with gentle protection and awareness.
At Sentinel Mouthguards, we merge cutting-edge 3D printing technology with handcrafted precision to create the most accurate, comfortable night guards possible. While 3D printing gives us unmatched model accuracy, our hands-on finishing process ensures every guard fits naturally and comfortably—because some details still require the human touch.
Tongue and cheek bites are tiny injuries that can cause big pain. Here’s how to soothe them quickly, what to avoid while healing, and how a custom relief guard can stop them from happening again.
