Custom Night Guard vs. Store-Bought: Which Protects Your Teeth Better?
If you grind or clench your teeth at night, the guard you wear makes a real difference. A custom night guard is made from impressions of your own teeth, while a store-bought guard is shaped to fit as many mouths as possible.
The two are not equal in fit, comfort or lifespan. Our dentists in Bellevue, WA help patients weigh them often.
Here's how the two options compare.
Why the Right Guard Matters
Grinding and clenching put heavy force on your teeth while you sleep. Over time, that force can lead to tooth erosion and cracks, along with sore jaw muscles and morning headaches.
Repairing that wear can mean crowns or a full mouth rejuvenation plan. A well-made guard is a more conservative first step.
Fit: Made for You or Made for Everyone
Store-bought guards come in two styles. Stock guards are worn straight out of the package, and boil-and-bite guards are softened in hot water so you can press them into a rough shape.
A custom guard starts with precise impressions of your teeth. Because it follows the contours of your bite, it stays in place without you clamping down to hold it.
Fit affects comfort, too. Cleveland Clinic notes that a poorly fitting mouth guard can cause soreness in the teeth, gums or jaw.
Thickness and Material
Over-the-counter guards are often thick and soft so one shape fits many smiles. That bulk can feel awkward to wear nightly.
A custom guard is planned for your mouth, so it covers what it needs to and little more. Ours use high-quality materials made for nightly wear.

Jaw Position and Comfort
According to Cleveland Clinic, a custom guard can place your jaw in a more favorable position to ease strain on the TMJ muscles. A generic guard can't be planned around your bite in the same way.
Federal dental researchers also advise making sure a guard is not designed to permanently change your bite. If any guard causes pain, stop wearing it and call your dentist.
Durability and Cost Over Time
Store-bought guards cost less at the register. They also wear out faster, and Cleveland Clinic notes you may need to replace one a few times a year.
A custom guard costs more up front, but with proper care it can last several years. Over that time, the cost gap may be smaller than it looks.
When a Boil-and-Bite Guard Is Fine Short Term
A boil-and-bite guard can work as a stopgap. It may help if you just noticed grinding, are waiting on a custom guard, or need a spare for a trip.
It is not a long-term answer for ongoing grinding. Waking up with jaw soreness, headaches or a new chip is a sign to see a dentist, since a damaged tooth may need a filling or a crown.

Frequently Asked Questions
Can a night guard stop me from grinding my teeth?
A night guard protects your teeth rather than curing the habit. It acts as a cushion, so the force of grinding and clenching lands on the guard instead of your enamel.
Cleveland Clinic notes that most people who grind can ease their symptoms with a custom mouth guard. If stress or another cause plays a role, your dentist can talk through next steps.
How does Kevin M. Brown DDS make a custom night guard?
Our dental team starts by taking precise impressions of your teeth during a visit to our Bellevue office. Your guard is then custom-made to fit the unique contours of your teeth.
That close fit is what lets the guard stay comfortable through the night. If anything feels tight or sore once you start wearing it, let us know so we can take a look.
How should I clean my night guard?
Rinse your night guard with water each morning and brush it gently with a soft toothbrush to remove debris. Let it dry before you put it back in its case.
Keep it away from hot water and direct sunlight, which Cleveland Clinic warns can warp the material. A warped guard may no longer fit the way it was designed to.
Can a night guard change my bite?
A properly made night guard is designed to protect your teeth, not move them. The National Institute of Dental and Craniofacial Research explains that these appliances fit over the teeth and do not change the teeth or bite.
The same agency advises choosing a guard that is not designed to permanently change your bite. Stop wearing any guard that causes pain and call your dentist.
Should I bring my night guard to dental checkups in Bellevue?
Yes, bringing your night guard to checkups lets our team inspect it for cracks, thinning or changes in fit. Regular visits help make sure it still gives you the protection you need.
Cleveland Clinic also recommends bringing your guard to dental visits. When wear starts to show, we can let you know whether it is time for a replacement.
