A custom nightguard is an investment in protecting your teeth, and a little daily care keeps it clean, fresh, and lasting as long as possible. A guard that is not cleaned properly can collect bacteria, develop an odor, and wear out sooner. The good news is that caring for one takes just a minute a day. Here is a simple, practical routine, plus the things to avoid.
Clean it every morning
The most important habit is to clean your guard right after you take it out in the morning, while any film is still fresh and easy to remove. Rinse it thoroughly under cool or lukewarm water, then gently brush it with a soft toothbrush. You can use a small amount of mild liquid soap or a non-abrasive toothpaste. Rinse again well so no soap residue is left behind. This quick routine prevents buildup before it has a chance to harden.
Let it dry before storing
Bacteria thrive in moisture, so let your guard air dry completely before putting it away. Set it on a clean surface for a few minutes after cleaning, then store it in its case. A dry guard in a dry case stays much fresher than one sealed away damp.
Store it the right way
Keep your nightguard in a sturdy, ventilated case whenever it is not in your mouth. A case with air holes lets it dry and protects it from damage. Keep it out of direct sunlight and away from heat sources like a car dashboard or a windowsill, since heat can warp the material and ruin the fit. And keep it somewhere pets cannot reach, because dogs in particular are notorious for chewing nightguards.
Deep clean it regularly
In addition to daily cleaning, give your guard a more thorough cleaning every week or so. You can soak it briefly in a mix of water and a small amount of mouthwash, or use a denture or retainer cleaning tablet according to the package directions. This helps keep it fresh and reduces buildup you cannot see. Always rinse well afterward before wearing it again.
What to avoid
A few common mistakes can shorten the life of a guard. Steer clear of these:
- Hot or boiling water, which can warp the guard and change the fit.
- Harsh chemicals like bleach, which can damage the material.
- Abrasive or whitening toothpastes, which can scratch the surface.
- Leaving it loose in a bag or pocket where it can be crushed or get dirty.
- Leaving it in a hot car or sunny windowsill.
Know when to replace it
Even with great care, a nightguard does not last forever, especially if you grind heavily. Watch for signs of wear like thin spots, cracks, a guard that no longer fits snugly, or one that has developed an odor you cannot clean away. If you are choosing between options, our comparison of custom vs store-bought nightguards explains why custom guards generally last longer. And if you are not sure you even need one, review the signs of nighttime grinding.
