Preventive Dentistry

Built for impact, not for sleep.

A mouth guard is worn during sports and other activities where a blow to the face is a real possibility. It's a different appliance with a different job than a night guard — this one is about protecting teeth from an outside impact, not from grinding.

What it is

A cushion against impact, not against clenching.

A mouth guard cushions the teeth, lips, and surrounding tissue during activities where contact or a fall is part of the game — basketball, football, hockey, martial arts, and similar sports. It helps absorb and distribute impact forces that might otherwise be concentrated on the teeth and surrounding tissues.

That's a different purpose than a night guard, which is worn during sleep to manage the effects of grinding and clenching. The two aren't interchangeable, and we'll help you get the right one for what you actually need.

When it may be appropriate

Any sport where a hit to the face is on the table.

Contact and collision sports are the clearest case, but plenty of other activities carry real risk of a fall or an elbow to the mouth — cycling, skateboarding, gymnastics, and recreational pickup games among them. If there's a realistic chance of a blow to the face, a mouth guard is worth considering.

It's also worth a conversation if you already have crowns, veneers, bridgework, or other restorative work — an impact that a natural tooth might shrug off can do more damage to dental work that isn't protected.

Benefits and trade-offs

Fit is what separates a good guard from an ignored one.

What it does well

A properly fitted guard stays in place during play, doesn't interfere with breathing or speaking as much as a bulky off-the-shelf version, and spreads impact force away from any single tooth.

What to weigh

Different sports and different mouths call for different designs — thickness, coverage, and material can all vary by activity and by patient. A mouth guard also isn't a guarantee against every dental injury or every concussion; it reduces risk, it doesn't eliminate it.

What patients can expect

A guard shaped around your own bite.

A custom guard starts with an impression or scan of your teeth, so the fit follows the actual shape of your mouth rather than a generic mold.

We'll talk through what your sport and level of play typically call for, so the guard fits both your mouth and how you'll actually use it.

Long-term considerations

Growing mouths and worn guards both need rechecking.

For younger athletes, teeth and jaws change as they grow, so a guard that fit well a season ago may not fit as well now. Guards also wear down with regular use. Checking the fit periodically keeps the protection where you actually need it.

Heading into a new season? Let's get a proper fit.

A consultation is a conversation, not a commitment. We'll talk about your sport and what makes sense for you.
