Jaw pain, sensitive teeth, morning headaches — these may all trace back to one hidden culprit: teeth grinding. Left untreated, bruxism can lead to broken teeth, TMJ disorders, and chronic pain. This complete guide explores the symptoms, causes, and risks of teeth grinding — and most importantly, the proven ways to find relief and protect your smile.
Finishing braces or Invisalign is just the beginning—retainers keep your smile straight. Discover how long you should wear a retainer, what to expect at each stage, and why consistent wear is the secret to lasting results.
Dental retainers are essential for keeping your teeth in place after orthodontic treatment — but how long should you wear them, how do you clean them, and when should you replace them? This complete guide breaks it all down and shows why Sentinel retainers offer dentist-grade quality at a fraction of the cost.
Can you wear a night guard during the day? The answer is yes—but it’s not always the most practical choice. While a standard night guard can protect your teeth from clenching and grinding outside of bedtime, it may feel bulky, affect speech, and wear out faster with all-day use. This article explores the benefits, drawbacks, and the best daytime-friendly alternatives—like slim, nearly invisible guards—so you can protect your smile 24/7 without sacrificing comfort.
Not all night guards are created equal — and some contain materials that may trigger irritation or allergic reactions. Common culprits like MMA (methyl methacrylate), PVC, and latex can cause redness, swelling, or discomfort in sensitive individuals. At Sentinel Mouthguards, we take the guesswork out of safety. Our custom night guards are crafted from dental-grade EVA and copolyester — completely free from MMA, PVC, latex, phthalates, and silicone — so you can protect your smile with total confidence.
