Review on 🧼 Optimized 3-Pack of Fresh Guard Soak by Efferdent for Cleaning Guards & Retainers, 24 Count by Veronica Fermin

This product is very aggressive. The powder made me cough every time I poured it into a jar to clean my night shield, but more importantly, it left a chemical coating on my night shield that essentially burned the inside of my mouth. The inside of my cheeks, upper and lower lip have been affected for a few months. It's like I've been sucking on sunflower seeds all day and the salt has wrinkled my mouth from the inside. This feeling lasted for several weeks even after I stopped wearing night guards. So if you are sensitive to chemicals, do not use this. My $450 Dental Night Protection is now useless, the chemical will not get out of this product.
