You wake up, and before you have even had coffee, your jaw already aches. Maybe it is a dull headache near your temples, a tooth that suddenly feels sensitive, or a partner who says you make a grinding sound in your sleep. If any of that sounds familiar, there is a good chance you grind or clench your teeth at night, and your smile is quietly paying the price.

The good news? Protecting your teeth while you sleep is one of the simplest things you can do in all of dentistry. Here is everything you need to know about night guards: how they work, how to tell if you need one, and what one really costs.

What Is a Night Guard and How Does It Work?

A night guard is a slim, custom-fitted tray that slips over your teeth while you sleep. Think of it as a cushion between your upper and lower teeth. When you clench or grind (your dentist will call it bruxism), the guard absorbs the force so your enamel, fillings, and jaw joints do not have to.

A custom night guard is made from precise impressions of your own teeth, so it fits snugly, stays in place, and is thin enough that most people forget they are wearing it after the first week or two.

How Do You Know If You Grind Your Teeth at Night?

Here is the tricky part: grinding happens while you are asleep, so most people have no idea they are doing it. Watch for these common signs:

• Jaw soreness, tightness, or clicking, especially in the morning
• Frequent morning headaches around your temples
• Teeth that look flattened, chipped, or shorter than they used to
• New or growing tooth sensitivity to hot and cold
• A partner who hears grinding or scraping sounds at night
• Scalloped edges on your tongue or bite marks inside your cheeks

Even if you have never noticed a thing, your dentist often can. Worn enamel and tiny stress cracks show up clearly during routine dental checkups, which is one more reason not to skip them.

What Happens If You Ignore Teeth Grinding?

Grinding puts hundreds of pounds of force on your teeth, night after night. Left alone, that pressure adds up:

• Enamel wears down, making teeth sensitive and more prone to decay
• Fillings crack and dental crowns chip or come loose
• Teeth can fracture badly enough to need root canals or extractions
• Jaw muscles and the TMJ (the joint in front of your ears) become painful and tight

In severe, long-term cases, grinding can wear teeth down so far that patients need full mouth restoration to rebuild their bite. A night guard is a small step that helps you avoid a very big one.

Custom Night Guard vs. Store-Bought: What Is the Difference?

You have probably seen boil-and-bite guards at the pharmacy, and it is fair to wonder whether they do the same job. Here is how the two compare:

• Fit: A custom guard is made from exact molds of your teeth. Store-bought guards are one-size-fits-most, which usually means bulky and loose.
• Comfort: Custom guards are slimmer and easier to sleep in. Many people give up on pharmacy guards within a few nights because they feel like a mouthful of plastic.
• Protection: A custom guard spreads biting force evenly. A poorly fitting guard can concentrate force in the wrong places and even shift your bite over time.
• Durability: Custom guards are made from dental-grade materials and typically last for years. Soft drugstore guards often chew through in months.

For occasional, mild clenching, an over-the-counter guard is better than nothing. If you grind regularly, a custom guard is the safer investment for your teeth.

Is Your Teeth Grinding Linked to Sleep Apnea?

Here is something many people do not know: nighttime grinding and sleep-disordered breathing often go hand in hand. For some patients, clenching is the body’s response to a partially blocked airway during sleep.

If you also snore loudly, wake up gasping, or feel exhausted no matter how long you sleep, mention it to your dentist. You may benefit from a sleep apnea oral appliance instead of, or alongside, a standard night guard. Treating the breathing issue can calm the grinding too, so it is worth getting the full picture before choosing an appliance.

How Much Does a Night Guard Cost?

Cost is usually the first question, so let’s talk numbers.

Over-the-counter guards run about $15 to $60. Custom night guards made by a dentist typically range from around $300 to $800, depending on the material and the complexity of your bite. That difference buys you a precise fit, stronger materials, and a guard designed for the way you actually grind.

Many dental insurance plans cover part of the cost of a custom night guard when grinding is documented, since protecting your teeth now prevents far more expensive repairs later. One cracked tooth that needs a crown can easily cost more than the guard that would have prevented it. Our team is happy to check your benefits and give you an exact quote before anything is made.

How Do You Care for Your Night Guard?

A little routine keeps your guard clean and comfortable for years:

• Rinse it with cool water every morning, then brush it gently with a soft toothbrush
• Let it dry fully before closing the case to prevent bacteria buildup
• Keep it away from heat and hot water, which can warp the fit
• Bring it to your dental visits so we can check the fit and wear
