Report
Most kinds of toothpaste contain glycerin that may do more harm than good. The thing is, glycerin coats the teeth and prevents remineralization. Like bones, teeth are composed of calcium, phosphorus, and other minerals, which are all delivered to teeth through saliva. When these minerals cannot get in teeth, your teeth are not as strong as they should be. So, make sure you buy glycerin free toothpaste.
