These lightening products and products which help improve your teeth may be considered by the FDA to be food products because they are not labeled as food, even though they are made from plants. I have written more about this in my book "Healthy Eating: How to Eat and Still Be Healthy". These are the top 10 best dental whitening products that have been scientifically proven to make your teeth brighter. These are not the only ones, but some are most beneficial to your teeth, but they are definitely the best. 1. Dental Whitening Cream Dental Whitening Creams are one of the most effective whitening treatments. They are very inexpensive and have a great side effect-they whiten the back of your teeth, and also your gums. There are lots of products on the market, but I suggest you get this one by Kool Aid. You can get it at Walmart, Walgreens or your local pharmacy. 2. Denture Whitening Gel I have written a review of this product in the past. I just bought the same bottle of it from my local Walgreens pharmacy a couple of days ago. This is my 2nd brand of denture whitening gel. It is one of the most expensive.
