Tooth Powder Dentifrices, including toothpowder and toothpaste, are agents used along with a toothbrush to clean and polish natural teeth. They are supplied in paste, powder, gel or liquid form. Many dentifrices have been produced over the years, some focusing on marketing strategies to sell products, such as offering whitening capabilities. The most essential dentifrice recommended by dentists is toothpaste which is used in conjunction with a toothbrush to help remove food debris and dental plaque. Dentifrice is also the French word for toothpaste.
