Commercial toothpastes, even natural brands, leave a greasy film on the teeth. Your mouth will feel clean and refreshed and some have found dental soap to be naturally whitening to their teeth. No fluoride added. Ingredients: Saponified oils of coconut, olive, and palm, clove bud essential oil and xylitol. 100% natural ingredients.
