"a barrier that prevents new stains…"
Sure, we all know it is important to brush our teeth to keep them as healthy as possible for as long as possible. But the choice of the toothpaste is also a very important aspect. I always recommend to my patients a toothpaste which maintains a barrier that prevents new stains from forming as they eat and drink during the day. A toothpaste that uses potassium nitrate to relieve sensitivity and sodium tripolyphosphate to block future stains. More over if the toothpaste tubes are eco-friendly, consisting of recycled materials.
