You just picked up a mouthguard for your kid’s soccer season, and now your dentist is telling you that you need a nightguard because you grind your teeth. It can sound like the same piece of plastic with two different price tags, so it makes sense to wonder if you actually need both. The truth is, these appliances protect against completely different threats, and using the wrong one can leave your teeth vulnerable to damage.
At Sunrise Dental Arts, we often see this confusion, especially among patients who play sports and experience jaw tension or morning headaches. Our team helps San Diego patients understand which of our dental procedures fit their specific needs rather than relying on a generic drugstore solution. The difference becomes much clearer once you understand what each guard is designed to do.
What A Sports Mouthguard Is Designed To Do
A sports mouthguard is designed to absorb sudden impact, such as a stray elbow during basketball or a fall off a bike. It is intentionally thicker than a nightguard, helping cushion your teeth, lips, and jaw while distributing the force of a hard hit across a wider area.
According to the American Academy of Pediatric Dentistry, dental injuries occur at a rate three times higher during competition than during practice, and most athletes involved were not wearing a mouthguard. A properly fitted sports guard can reduce the risk of serious dental injuries and is an important preventive step for patients who regularly participate in activities where impacts and falls can happen.
What A Nightguard Is Designed To Do
A night guard faces a different kind of risk than a sports guard. Instead of protecting against sudden impact, it protects your teeth from the repetitive pressure caused by nighttime grinding and clenching, known as bruxism. Because it is worn for hours while you sleep, a nightguard is designed to fit comfortably against your teeth without the bulk of a sports guard.
Over time, chronic grinding can wear down enamel, crack teeth, and contribute to jaw pain or frequent headaches. A nightguard creates a barrier between your upper and lower teeth, helping protect your enamel from those forces. Many patients do not realize they grind their teeth until we spot signs of wear during a routine exam, which is another reason regular checkups matter even when nothing feels wrong.
Why You Might Need Both
If you play sports and also grind your teeth at night, you are dealing with two separate risks that call for two separate solutions. A sports guard worn during a game will not help you overnight, and a nightguard would not survive a hard hit on the field, because it is not built to withstand that kind of force. Wearing the wrong guard for the situation means you are only half-protected, which defeats the purpose of wearing one at all.
- A sports mouthguard protects against sudden trauma during games and practices
- A nightguard protects against gradual wear from grinding and clenching
- Custom versions of each fit your exact bite, unlike one-size-fits-all store options
This is exactly why we take the time to evaluate what is actually happening in your mouth before recommending a guard, rather than assuming one appliance can do double duty. Grinding can also chip or wear down existing dental bonding over time, which is another reason a nightguard is worth discussing even if you think your grinding is mild.
Custom Guards Versus Store-Bought Options
It is worth mentioning that boil-and-bite guards from the drugstore are better than nothing, but they rarely fit as well as a custom option made from an impression of your own teeth. A guard that shifts around or feels bulky is one you are less likely to wear consistently, which defeats the purpose entirely. Custom-fitted guards stay in place, feel more natural, and actually get worn night after night or game after game.
If you have ever tried a store-bought guard and given up on it within a week, a custom fit is likely the reason your experience will be different this time. We often see patients who assume all mouthguards feel bulky and uncomfortable simply because they have never tried one designed for their own teeth. For patients who have invested in dental implants, a properly fitted nightguard also helps protect that restorative work from unnecessary grinding pressure over the years.
