Wondering if mouthwash and night guards mix well? If you’ve ever asked, “Can you use mouthwash with a night guard?” this guide explains what to watch out for, which products are safe, and how to keep your dental device clean and long-lasting.
“Not all mouthwashes are created equal — the right rinse can freshen your breath without damaging your night guard.”
It might seem simple to toss your night guard into a cup of mouthwash for a quick clean — but some formulas contain alcohol and acids that can damage the material over time. Mouthwash with alcohol can dry out and warp your guard, making it less effective or even uncomfortable to wear.
Instead, it’s best to rinse your night guard with cool water and use a mild, alcohol-free mouthwash if you prefer a fresh scent. NewSmile’s night guards are made from high-quality, BPA-free material designed to resist odor and bacteria buildup when cleaned properly.
“Clean your guard like you brush your teeth — consistently and gently for long-lasting protection.”
When shopping for a compatible mouthwash, choose formulas labeled alcohol-free, gentle, or for sensitive mouths. Brands like TheraBreath, CloSYS, and ACT offer dentist-approved rinses that keep your mouth fresh without harming your guard.
After cleaning, you can briefly soak your guard in diluted mouthwash (one part rinse to four parts water) for 1–2 minutes — but avoid long soaking sessions. For all-around oral protection, NewSmile’s custom night guards are designed for easy cleaning and daily use, helping users maintain freshness effortlessly.
If your guard starts to smell even after cleaning, looks cloudy, or feels rough, it’s time to deep-clean or replace it. Over time, microscopic scratches can trap bacteria — another reason to avoid harsh mouthwashes and abrasive cleansers.
