I was skeptical
I was skeptical. I wear a mouth guard at night for grinding. It was pretty yellow. I let it soak as recommended and ran it for 10 minutes. It was almost clear. I've been getting a new guard every 3 months. Now I won't have to. I'm excited about saving money. I quickly bought one for my grandson who just got a new retainer.
