The Only Complete Solution That Stops It for Good
If you’re waking up with painful cheek sores, inflamed tissue, or even small cuts inside your mouth, you’re not alone.
Cheek biting at night is surprisingly common — and it can be both painful and hard to stop.
The good news? There’s a way to stop it entirely.
While most mouth guards protect only one row of teeth, Sentinel’s Tongue & Cheek Biting Relief Guards protect both — eliminating the ability for your teeth to grip and catch your cheeks at all.
🩵 This article is part of our comprehensive guide to tongue and cheek biting relief — a complete resource to help you understand the causes, treatments, and long-term prevention options.
🤔 Why Cheek Biting Happens
Chronic cheek biting typically comes from one or more of these:
-
Nighttime clenching or teeth grinding (bruxism)
-
Stress or anxiety tightening facial and jaw muscles
-
Dental misalignment or changes from crowns, fillings, or tooth movement
-
Sleep disturbances or muscle spasms that cause involuntary jaw movement
When your upper and lower teeth meet without protection, they can pull or “trap” your cheek tissue — leading to painful, slow-healing injuries.
🦷 Why Single Mouth Guards Don’t Fully Solve It
Standard night guards — whether soft, hard, or dual-laminated — cover only one arch (upper or lower).
While they help cushion teeth and reduce grinding, they still allow the uncovered arch to contact the cheek.
That means you can still catch the cheek tissue between your teeth, especially if you clench or move side to side in your sleep.
It’s a bit like putting a glove on one hand and expecting it to stop both from clapping.
💚 The Complete Fix: Sentinel’s Tongue & Cheek Biting Relief Guards
Unlike traditional single-arch guards, Sentinel’s Tongue & Cheek Biting Relief Guards are sold as a set — one upper, one lower — custom-made from your dental impressions to perfectly fit your bite.
Here’s how they work:
-
Full occlusal coverage: Both upper and lower teeth are covered, which means there’s no direct tooth-to-tooth contact and no way to catch your cheek.
-
Smooth, soft material: The guards are made from a thin, flexible, medical-grade thermoplastic that feels comfortable and gentle against soft tissue.
-
Custom fit for comfort: Because they’re molded from your exact impressions, they stay secure through the night — no slipping or rubbing.
-
Completely eliminates cheek trauma: With both arches protected, your teeth simply can’t grip or pinch your cheek, no matter how you move your jaw.
💚 The result: instant relief and long-term protection.
🩹 How Fast Does It Work?
The relief is typically immediate.
Once both guards are in place, you can’t bite your cheeks — period.
Within a few nights, inflammation and soreness begin to fade. Within a week or two, the tissue is usually fully healed.
🧠 Why Custom-Fit Guards Are Worth It
You can find cheap boil-and-bite guards online, but they’re bulky and rarely cover both arches comfortably.
They can even make cheek biting worse by pushing tissue inward.
Sentinel’s guards are:
-
Custom-fit for precision and comfort
-
Latex-free, BPA-free, phthalate-free
-
Made in the USA using premium dental materials
-
Hand-finished and polished for a smooth surface that’s gentle against the cheeks
-
Digitally scanned and stored for fast, easy reorders — no new impression needed unless your bite changes
🧩 Other Ways to Support Healing
While your guards do the heavy lifting, you can help your mouth heal faster by:
-
Rinsing with warm salt water 2–3 times daily
-
Avoiding spicy or acidic foods that can sting or irritate
-
Keeping your guards clean and dry between uses
-
Managing stress and tension, which often trigger clenching
