Burns Gums.
I received this product a day ago. I tried it and I could only wear it for a minute.I thought my tooth was falling out.it touch my tongue and burn the hell out of my gums and teeth. Don't recommend this at all. Teeth hurt like crazy after I rinse it out of my mouth. My tongue has sores.<br />Stick to brushing your teeth. Eventually you will get white teeth.
