I have done some experimenting with products, and in order to make it into our routine for good they must work well and be a good price. Here's a couple that I have found:
Tom's of Maine ToothpasteThis brand has many flavors to choose from but we prefer the Peppermint Baking Soda with Fluoride. We experimented with other natural brands without fluoride, but we noticed our teeth started to hurt after a while. This one works great and we have been using it for years with no cavities. After you have used a natural toothpaste for a while, if you use a conventional brand it will actually feel like your mouth is burning and have sickly sweet taste.
We preferred the original recipe, before the company sold out (google it for more info). The updated version was not as good, but they seem to have made some adjustments, and it is better now. It is more expensive than conventional brands, but we can buy it online in multi-packs and save money.
