You wake up with a dull headache. Your jaw feels tight. Your teeth are sensitive to cold water. You chalk it up to stress. A bad night’s sleep. Maybe you slept with your mouth open. But could you be grinding your teeth while you sleep?
It’s more common than you’d think. And most people have no idea they’re doing it.
Why Nighttime Grinding Is So Easy to Miss
Bruxism is the technical term for teeth grinding and clenching. It can happen during the day, but nighttime grinding is the sneaky version because you’re asleep. You’re not aware of it. No one can tell you it’s happening unless your partner notices the sound. Unlike daytime clenching, which you might catch yourself doing during a stressful meeting, nighttime grinding happens completely under the radar.
Some people grind occasionally. Others do it every single night, for hours at a time. Over months and years, that pressure adds up.
Sign #1: Worn, Flattened, or Chipped Teeth
This is often the first thing we notice during an exam. Natural teeth have ridges, grooves, and slightly rounded edges. Ground-down teeth look flat. The chewing surfaces get worn smooth. The edges of your front teeth might look uneven or chipped.
If your teeth look shorter than they used to, or if you can see yellow dentin showing through where enamel has worn away, grinding is a likely culprit.
Sign #2: Jaw Pain or Tenderness
Your jaw muscles work hard when you grind. Imagine clenching your fist for hours every night. Your hand would be sore. The same idea applies to your jaw.
Many patients describe waking up with a tired, achy jaw. It might hurt to open wide first thing in the morning. The muscles near your ears or along your cheeks may feel tender to the touch.
Sign #3: Morning Headaches
Grinding puts enormous strain on the muscles that connect your jaw to your skull. That tension radiates. Many people who grind wake up with headaches that feel like tension headaches, pressure around the temples, tightness in the forehead, sometimes pain that wraps around to the back of the head.
If you regularly wake up with a headache that fades as the day goes on, grinding deserves a closer look.
Sign #4: Sensitive or Loose Teeth
Grinding wears through enamel. Once enamel is gone, the sensitive layer underneath is exposed. That’s why many grinders suddenly notice their teeth hurt when they drink something cold or eat something sweet.
In more advanced cases, the constant pressure can even make teeth feel loose or shift out of alignment.
Sign #5: Broken Fillings or Restorations
If a filling, crown, or bridge comes loose or breaks without an obvious cause, grinding could be the reason. The force of nighttime clenching can crack restorations that would otherwise last for years.
What to Do About It
Nighttime grinding is manageable. The most common solution is a custom nightguard. This smooth, protective appliance fits over your teeth while you sleep. It doesn’t stop the grinding, but it absorbs the force so your teeth and jaw don’t take the brunt of it.
We make these right here in our office. They’re custom-fitted to your bite using impressions of your teeth, so they’re comfortable and effective, nothing like the bulky drugstore guards that never quite fit right.
Beyond a nightguard, we’ll also look at the bigger picture. Dr. Sang is trained to evaluate how your bite functions and whether misalignment is contributing to the grinding. Sometimes adjusting how your teeth come together can reduce the problem at its source.
Don’t Wait for the Damage to Add Up
Grinding doesn’t fix itself. And enamel doesn’t grow back.
If any of these signs sound familiar, come see us. Dr. Sang can examine your teeth for signs of wear and help you figure out whether a nightguard or another approach is right for you.
