Not a professional, but after a bit of research, I found that a lot of times cavities and dental issues are caused by bacteria in your mouth vs directly sugar alone. So I started using the IORinse, and it’s awesome! So are the rest of the products, including a (fluoride free) hydroxyapatite toothpaste! Don’t knock it until you try it! Again, we are super alternative and willing to try anything before using heavy metals and toxins! PS the io rinse is a concentrate to add to a water flosser!
