RetarDEX toothpaste contains no animal by-products and is non-foaming for superior oral care. RetarDEX toothpaste does not contain Sodium Lauryl Sulfate, the foaming detergent present in most toothpastes. This means that, as your mouth does not feel full of suds, you can carry on brushing your teeth for longer. RetarDEX toothpaste has a low level of abrasiveness due to the silica polishers contained in the paste and is effective at removing everyday staining from food, drink and tobacco.
