You wake up with a headache. Your jaw feels tight, almost sore. You shrug it off as stress or maybe a bad pillow. But what if the real culprit is something you’re doing in your sleep?
Teeth grinding, dentists call it bruxism, is one of those conditions that’s incredibly common yet surprisingly easy to miss. Why? Because you’re asleep when it happens. Most people have no idea they’re grinding until someone tells them or a dentist spots the damage. At Infinity Dental, Dr. Thomas Prendergast sees the signs of nighttime grinding all the time. But once we know it’s happening, we can help.

The Person Who Knows First Might Be Lying Next to You
Here’s the thing about grinding. You can’t hear yourself doing it. But your sleeping partner? They definitely can.
That clicking, clenching, or grinding sound can be loud enough to wake someone up. If your partner has ever mentioned strange noises coming from your side of the bed, don’t brush it off. They might be giving you a valuable clue about your oral health.
5 Telltale Signs You’re Grinding at Night
Not everyone has a partner to warn them. So here are five signs you can watch for on your own.
- Unexplained morning headaches. Grinding puts enormous pressure on the muscles in your jaw, face, and temples. That tension often shows up as a dull headache first thing in the morning. If your headaches tend to fade as the day goes on, grinding could be the reason.
- Jaw soreness or tightness. Do you wake up feeling like you’ve been chewing gum for hours? That’s not random. That’s your jaw muscles letting you know they’ve been working overtime while you slept.
- Worn, flat, or chipped teeth. This one doesn’t happen overnight. But over time, grinding literally wears down the chewing surfaces of your teeth. They may look shorter, develop small chips, or feel rough to your tongue. Dr. Prendergast can spot this type of wear immediately during a routine exam.
- Increased tooth sensitivity. As grinding wears away enamel, the hard outer layer of your teeth, the softer inner layer becomes exposed. That can make your teeth suddenly sensitive to hot, cold, or sweet things.
- Clicking or popping in your jaw. Chronic grinding can strain the joint that connects your jaw to your skull. If you notice clicking, popping, or even locking when you open your mouth wide, your nighttime habit may be partly to blame.
Why Grinding Hurts More Than Just Your Teeth
Grinding doesn’t just damage teeth. It can lead to loose teeth, gum recession, and even changes in your bite. Some people develop chronic facial pain that goes far beyond a morning headache. The longer grinding goes untreated, the more wear and tear builds up.
The Good News: There’s a Simple Solution
Dr. Prendergast offers a straightforward, comfortable fix for teeth grinding: a custom-made nightguard.
Think of it like a mouthguard for sleeping. It fits over your teeth and creates a protective barrier that absorbs the force of grinding instead of your teeth taking the hit. Patients are often surprised by how much better they feel in the morning once they start wearing one.
What to Do If Any of This Sounds Familiar
You don’t have to live with morning headaches or worn-down teeth. If any of these signs feel familiar, mention them at your next appointment. Dr. Prendergast can examine your teeth for wear patterns and help you figure out whether grinding is the culprit.
And if your partner has been dropping hints about nighttime noise? Believe them. Your smile, and your jaw, will thank you. Give us a call. We’ll help you wake up feeling better.
