Kohalt Niconin Dental Rinse 200ml Mouthwash Unopened This product is less irritating than typical mouthwashes, so it can be used by both children and adults. It can be used in combination with brushing and flossing to keep the mouth clean, and it's recommended because even just rinsing when you're in a hurry can temporarily prevent bad breath. ~From the product pamphlet~ You can use this product if your child can gargle on their own. Please refrain from using it on infants under 4 years old. There are 5 of the same item. We will offer a discount if you purchase them in bulk.
