How mouthguards help adults sleep better and protect their teeth

Waking up with jaw pain, headaches or worn-down teeth? You might need more than just a good night’s sleep—you might need a mouthguard. At Aspen Dental, we understand how exhausting it can be when your smile is working against you instead of for you. Mouthguards aren’t just for athletes anymore. They’re a simple, effective way to protect your teeth from grinding, clenching and other oral health issues that can disrupt your rest and damage your smile.

Our care team is here to help you find the best mouthguard for your needs and lifestyle. We’ll guide you through the options, explain the differences and make sure your guard feels comfortable enough to wear every night.

What are mouthguards and why do adults need them?

A mouthguard is a protective device that fits over your teeth to absorb pressure and reduce friction. While many people think of them as sports gear, more and more adults are using them to manage teeth grinding and jaw clenching—habits that often show up when stress is high.

The tricky part is that most people don’t realize they’re grinding or clenching until the symptoms pile up. Maybe you wake up with jaw soreness. Maybe your teeth feel more sensitive than usual. Or maybe you notice a small chip and wonder how it happened. It’s like snoring—you may not notice it yourself, but the signs are there if you know what to look for.

According to the American Dental Association, about 10–15% of adults grind their teeth at night. Over time, that can mean cracked teeth, worn enamel or chronic jaw pain. A well-fitted mouthguard acts like a shock absorber, softening the impact and giving your teeth and jaw the protection they need.

Common conditions mouthguards can help with

Teeth grinding (bruxism)

If you’ve ever chalked up your morning headaches to poor sleep, bruxism may be the hidden culprit. Grinding often happens in the deepest part of your sleep cycle, which makes it nearly impossible to stop on your own. A mouthguard creates a barrier between your upper and lower teeth so the grinding can’t wear them down. That simple cushion helps reduce strain, prevent chips and fractures and give you a chance to wake up feeling more refreshed.

TMJ and jaw clenching

Jaw clenching can be subtle but relentless. The clicking you hear when you yawn, the tightness that builds up after a stressful day or the dull ache near your ears—all of it adds up. Clenching can also worsen TMJ symptoms, making the joint feel unstable or sore. A custom-fit mouthguard encourages your jaw to rest in a more natural position, easing muscle tension and protecting against further strain. Patients often notice not only relief from discomfort but also an overall sense of relaxation.

Sports injuries and oral trauma

If you’re active—whether that’s basketball on the weekends, cycling long distances or joining a martial arts class—a mouthguard is as essential as a helmet. Sports guards are thicker than night guards and designed to absorb impact. They can help prevent broken or knocked-out teeth, cuts to the lips and tongue and even jaw injuries. Wearing one keeps your smile safe so you can focus on the activities you love.

Types of mouthguards for adults

Not all mouthguards are created equal. Some are meant for short-term or occasional use, while others are designed to protect your teeth night after night for years.

Custom-fit vs. boil-and-bite mouthguards

Custom-fit guards are made from impressions or scans of your teeth. Because they match your unique bite, they feel secure, stay in place and don’t rub against your gums or cheeks. That precision makes a big difference in comfort and consistency. Many patients find they adapt quickly to wearing one because it feels natural.

Boil-and-bite guards, available at most drugstores, can be softened in hot water and molded at home. They’re accessible and affordable, but the fit is less exact. Over time, they may feel bulky or wear down quickly, which can reduce protection. If grinding or clenching is frequent, a custom-fit guard usually offers better comfort and long-term value.

Choosing between over-the-counter and dentist-made options

Over-the-counter guards are convenient, but they can’t match the precision of a guard made by a dentist. One-size-fits-all materials can feel either too soft or too rigid, and they often don’t stay secure through the night.

At Aspen Dental, we start with an exam and a conversation. We look at how your teeth fit together, evaluate any wear or tenderness and design a guard that’s built for your exact needs—whether that’s easing jaw tension, managing grinding or protecting against sports injuries. You’ll also have the peace of mind that comes with professional guidance and ongoing support if your guard ever needs adjustments.

How to choose the right mouthguard for your needs

Comfort, fit and sensitivity

The right mouthguard should feel like it belongs. If it’s bulky, digs into your cheeks or slips around, chances are you won’t wear it consistently. A custom-fit guard is shaped for your teeth alone, with smooth edges and the right thickness to protect without getting in the way of breathing or speaking. For patients with sensitive gums or enamel, we can recommend materials that balance firmness and cushion so it feels protective without being irritating.

There is always an adjustment period, but most patients get used to their guard within a few nights. We’ll guide you through how to seat it properly, what a secure fit feels like and when to check back if something doesn’t feel right.

Cost, durability and insurance

Many patients wonder if a custom guard is worth the investment. While store-bought guards may cost less up front, they often wear down quickly and need replacing more often. A professionally made guard is built to last longer with proper care. Depending on your insurance plan, custom guards may also be covered when they’re considered medically necessary for conditions like bruxism or TMJ. At Aspen Dental, our team will help you understand your coverage and walk you through all your financing options and insurance so cost doesn’t become a barrier to protecting your smile.

Where can you get a custom mouthguard?

Why dental clinics are your best option

What to expect during a fitting at Aspen Dental

It starts with a consultation where we listen to your concerns and review your symptoms. Next, we take impressions or digital scans to create a detailed model of your teeth. That model guides the fabrication of your custom guard, ensuring it matches your bite and feels secure.

At your fitting appointment, we’ll test it together, make adjustments if needed and show you how to keep it clean and in good condition. We’ll also check in at future visits to confirm it’s still fitting properly and providing the protection you need.

Frequently asked questions about mouthguards

What is the difference between a boil-and-bite and a custom-fit mouthguard?

Boil-and-bite guards can be molded at home, but they don’t always fit securely or last very long. Custom-fit guards are made by a dentist using impressions or scans of your teeth. They provide a precise fit, more consistent protection and longer-lasting results. Most patients notice right away that a custom guard feels more natural, which makes it easier to wear every night.

Are mouthguards only for sports or can they help with teeth grinding too?

Mouthguards aren’t just for athletes. In fact, nighttime use is one of the most common reasons we recommend them. They can protect against grinding and clenching, reduce TMJ symptoms, and help you wake up with less pain and more energy.

Do I need a mouthguard if I wear dentures or have dental work?

Yes. Custom mouthguards can be designed to fit comfortably around dentures, crowns or other dental appliances without causing disruption. We’ll take into account any existing dental work to make sure your guard feels secure and supportive.

How do I know if I need a custom-fit mouthguard from a dentist?

If you grind your teeth, wake up with headaches or feel tension in your jaw, a custom-fit mouthguard may be the best solution. A consultation is the easiest way to find out. Even if you’re unsure, a quick evaluation can give you peace of mind and help prevent small issues from turning into bigger problems.
