Lamazuna solid toothpaste; no more excess fluoride! If you are looking for a toothpaste that is both highly effective and 100% natural, you have probably come to the right place. Lamazuna has created solid, natural, vegan and above all very well-composed toothpastes. Although they are akin to the most tantalizing sweets, these products are dedicated to dental hygiene and they do it very well. The main (and most common) ingredient in Lamazuna toothpaste sticks? Calcium carbonate, a natural ingredient known for its cleansing, purifying and shining action. To use your Lamazuna toothpaste, simply rub your toothbrush previously wet with hot water against the block of material at the end of the stick, then brush your teeth as usual (or better than usual, up to you. duty).
