Helps remove plaque for cleaner teeth. You'll love having your child brush with Orajel Toddler Training Toothpaste because it helps clean teeth with a special patented ingredient, Microdent. Best of all, it's fluoride-free so it's safe to swallow. Swallowing too much fluoride can cause fluorosis or white spots on your child's permanent teeth. This is especially important if your child doesn't quite have the skills yet to spit out all the toothpaste but yet loves to brush! Orajel Toddler Training Toothpaste also does not foam and is not abrasive. For toddlers up to 4 years old.
