If you participate in sports, you've probably heard about mouth guards. But did you know that 10 to 39 percent of all dental injuries happen during sports? Many of these injuries are preventable with proper mouth protection. Let's explore why mouth guards matter and which type provides the best protection.
How Often Do Sports Injuries Happen to Teeth?
Sports-related mouth and facial injuries are shockingly common. Contact sports like football, rugby, and ice hockey have the highest injury rates—about one in 10 to one in 60 athletes get injured annually. Even non-contact sports like basketball and baseball have significant injury rates.
When a tooth gets knocked out or broken during sports, it's not just a dental problem. A single traumatic injury often requires five to ten additional procedures to fix properly. The costs, pain, and long-term complications are substantial.

Why Custom Mouth Guards?
You can buy generic mouth guards at sporting goods stores. You've probably seen them—the cheap plastic ones. Unfortunately, these provide minimal protection. Stock mouth guards reduce injury risk by only 15 to 25 percent because they don't fit well and they move around during activity.
Boil-and-bite mouth guards, where you soften them in water and bite to mold them, are better. They reduce injury risk by 40 to 55 percent. But they wear out quickly and don't maintain good fit.
Custom-fabricated mouth guards made by dental labs provide the best protection—reducing injury risk by 85 to 95 percent. That's a huge difference. They fit your mouth perfectly, stay in place during intense activity, and provide superior shock absorption.
How Custom Mouth Guards Protect You
Custom mouth guards work through several protective mechanisms. First, they distribute the force of impact across a larger area. Without a guard, a blow concentrates force on one or two teeth. The guard spreads that force across your whole arch, reducing damage.
Second, the guard creates space between your teeth and your lower jaw. This prevents your teeth from smashing into each other and fracturing. The 3 to 4 millimeter thickness of the guard maintains separation even during hard impacts.
Third, the guard cushions impact to your jaw, mouth tissue, and supporting bone. This reduces soft tissue cuts (which are painful and leave scars), reduces fractures of supporting bone, and protects your teeth themselves.
Research shows that athletes with custom mouth guards experience 50 to 70 percent reduction in tooth loss, 60 to 80 percent reduction in tooth fractures, and 90 to 95 percent reduction in mouth cuts. Those are impressive protection numbers.
Getting a Custom Mouth Guard
Your dentist takes an impression of your upper teeth (where most injuries happen). Modern offices might use a digital scan instead, which is more comfortable and accurate.
The lab uses this impression to make a stone model of your mouth exactly. Learning more about Oral Health Habits Complete Guide can help you understand this better. They then heat special ethylene vinyl acetate (EVA) plastic material—the same stuff used in athletic shoes—and form it tightly over the model using vacuum pressure. The thickness is carefully controlled to provide maximum protection while still being comfortable enough to wear.
The finished guard fits like a glove. It stays in place without falling out, doesn't interfere with breathing or speaking, and can be worn for entire games or practices without discomfort.
Why Kids Need Mouth Guards Too
Growing children absolutely need mouth guards if they play sports. Their teeth are still developing, and a trauma to a young tooth can cause permanent damage affecting how permanent teeth erupt and develop. Plus, young athletes have many years of potential future injuries to prevent.
If your child has braces, they still need a mouth guard—a special one designed to work with orthodontic appliances.
Replacing Your Mouth Guard
A well-maintained mouth guard lasts about two to three years before the material starts degrading. However, athletic kids with intense grinding patterns might need replacement at 12 to 18 months.
As kids grow and their teeth erupt, new mouth guards are needed. Generally, mouth guards should be re-made or re-evaluated annually for growing children and every two to three years for adults.
You'll know it's time to replace yours when it becomes uncomfortable, doesn't fit as well, or the material looks worn or damaged.
Caring for Your Mouth Guard
To extend the life of your mouth guard:
- Rinse it daily with cool water after use
- Weekly, brush it gently with a soft toothbrush and mild soap
- Store it in a protective case with ventilation holes so it can air dry
- Never expose it to heat (keep it out of hot cars, don't put it in hot water)
- Never leave it in direct sunlight for extended periods
- Keep it in a case when not using it
Special Situations
If you play with braces, your dentist will make a custom guard accommodating the brackets and wires. Standard guards don't work with braces—they're uncomfortable and risk damaging expensive orthodontic equipment.
If you've had teeth replaced with implants or crowns, protecting those restorations with a mouth guard is especially important. These restorations cost thousands of dollars—protecting them makes financial sense.
If you have jaw joint problems (TMJ dysfunction), talk to your dentist about mouth guard design. They can sometimes modify designs to help rather than aggravate your condition.
Speaking and Breathing With a Guard
Good custom mouth guards shouldn't significantly affect your ability to speak or breathe. Some athletes worry they'll have trouble talking during games or practices.
In reality, well-fitted custom guards made by experienced dental labs allow normal speech and breathing. Some adjustment period is typical—first wearing might feel slightly awkward—but within a practice or two, most athletes barely notice they're wearing it.
Thick guards or poorly fitted guards might interfere with speech. This is why custom fabrication matters. Quality guards minimize these issues.
Compliance and Staying Safe
The best mouth guard provides no benefit if you don't wear it. Research shows that 30 to 45 percent of athletes who get mouth guards don't wear them consistently.
Reasons include discomfort, difficulty speaking, or not wanting to look silly. The solution is getting a high-quality custom guard designed for comfort and made from clear material so it's less visible. Coaches and parents insisting on use also helps tremendously.
Athletes whose parents emphasize mouth guard use show 40 to 50 percent higher compliance than athletes without parental reinforcement. When coaches make mouth guard use part of standard practice expectations, compliance improves even more.
Professional Inspection
Your dentist should inspect your mouth guard annually. They'll check for material degradation, make sure the fit is still appropriate, and determine if replacement is needed.
Growing children need more frequent inspection. As their teeth erupt and their jaw grows, the mouth guard might not fit properly anymore.
Conclusion
Custom mouth guards provide outstanding protection against sports-related tooth injuries—reducing tooth loss, fractures, and mouth cuts by 60 to 95 percent. They're comfortable, allow normal speech and breathing when properly made, and last two to three years with good care. For anyone participating in organized sports or high-impact activities, a custom mouth guard is one of the best investments you can make for your dental health and safety. Talk to your dentist about getting a properly fitted custom mouth guard before your next season starts.
