Bruxism and TMD can cause some of the same symptoms, but they are not the same thing. Bruxism describes jaw-muscle activity such as grinding and clenching, while TMD refers to disorders affecting the jaw joints and chewing muscles. Learn how they differ, where they overlap, and why one does not automatically cause the other.
Teeth clenching and teeth grinding are both forms of bruxism, but they involve different jaw movements and can happen while you’re awake or asleep. Learn how to tell them apart, what signs to watch for, and when a night guard may help protect your teeth.
Grinding and clenching can place repeated stress on teeth over time. This guide explains the science behind mouth guard protection, including force, contact area, enamel wear, fit, material behavior, and why night guards differ from sports mouth guards.
Teeth grinding rarely causes dramatic damage overnight. Instead, enamel can gradually wear away, teeth may become flatter or shorter, and fillings, crowns, veneers, or bonding can begin to fail over time. Learn how long-term bruxism changes your teeth, what damage may be permanent, what can often be restored, and how to protect the healthy tooth structure you still have.
Wake up with sore teeth? Learn the most common causes of morning tooth pain—including teeth grinding, clenching, TMJ, sinus pressure, and when to see a dentist.
Dogs love night guards for the same reasons we hate losing them: they smell familiar, fit perfectly in a mouth, and are easy to chew. Here’s what to do next—and how to replace yours.
Paying $500–$1,000 for a custom night guard at the dentist often surprises patients—especially when they discover that much of the cost reflects office visits, clinical care, and practice overhead rather than the appliance itself. While dentists provide valuable services, many people can now order a professionally manufactured custom night guard directly from an FDA-registered laboratory using the same high-quality materials for significantly less. In this article, we'll explain what you're paying for, where the savings come from, and how to decide which option is right for you.
A night guard should feel secure, not painful. Tooth soreness can come from excessive pressure, poor seating, changes in your teeth or an unrelated dental problem. Learn what to check and when the appliance needs evaluation.
Night guard safety is about more than a BPA-free label. Learn what to know about materials, fit, chemical claims, allergies, cleaning and long-term nightly wear—without the scare tactics.
