A mouthguard only protects your teeth if it fits securely and stays put — which is the biggest difference between a custom guard from your dentist and a store-bought one. Custom, boil-and-bite, and stock guards all fit differently, and that affects comfort, stability, and protection.
This updates our earlier guide, custom vs. OTC mouthguards.
How the options compare
- Custom (from a dentist): made for your teeth; snug and secure; highest cost.
- Boil-and-bite: molded at home; more personalized than stock; moderate cost.
- Stock: standard size; can feel bulky or loose; lowest cost.
Why fit matters
A sports mouthguard needs to stay in place while you move, breathe, and talk. A loose or bulky guard is distracting and harder to keep positioned over your teeth when you actually need protection. A closer fit is more comfortable and more likely to stay put — which is why fit is the main dividing line between custom and over-the-counter guards.
Are custom guards worth the cost?
Custom guards cost more up front, but the personalized fit, comfort, and durability can make them worth it if you regularly play contact or high-impact sports. A stock guard can still be practical for occasional use, and boil-and-bite sits in the middle.
What if you have braces?
If you wear braces or other orthodontic appliances, the right guard matters even more — it needs room to protect your teeth and hardware without interfering with treatment. Ask your dentist or orthodontist which type fits your sport and your braces.
Frequently asked questions
Are custom mouthguards worth it?
If you play contact or high-impact sports regularly, the personalized fit, comfort, and durability of a custom guard usually justify the higher cost. For occasional use, a store-bought guard may be enough.
Do boil-and-bite mouthguards work?
Yes, reasonably well. They give a closer fit than stock guards at a lower cost than custom, as long as you mold them carefully following the instructions.
Why does mouthguard fit matter?
A guard that shifts or feels bulky is distracting and may not stay over your teeth on impact. A secure fit makes it more comfortable and more protective.
Can you wear a mouthguard with braces?
Yes, but choose one made to fit over orthodontic hardware. Ask your dentist or orthodontist which type is right for your sport and your braces.
