I'm almost out of toothpaste, so I decided to try switching to Tom's of Maine. I got the cinnamon flavor, as I dislike mint for the most part. Unfortunately, I had a very painful few days before I gave up on it. The toothpaste burned the inside of my mouth.
At first I thought that the cinnamon was very strong and I wasn't used to it, or just changing to a new toothpaste for the first time in years, or maybe my gums were having a sensitive day. But it happened again, and again, and finally after 3 days of trying to use the smallest amount possible I decided it wasn't worth it any more. Even a day after I stopped and went back to my old toothpaste, parts of my mouth are still tender.
I sent Tom's a message, asking for a refund, and they've agreed. It's only a few dollars, but it's the principle of the thing.
I also got a new toothbrush, made by Preserve and purchased at Trader Joe's. It's made of recycled yogurt cups, and comes in a plastic sleeve that serves as a pre-paid mailing envelope. The idea being that once you use the toothbrush, you put it back in the package, tape the thing closed and mail it back so it can be recycled through Preserve's Gimme 5 program. If I have to get a toothbrush, I'm a fan of this plan.
