Over thousands of years, different cultures used different ingredients for their tooth powders and pastes, such as crushed tree bark, oyster shells, chalk, and charcoal. Charcoal is still a common ingredient for particular brands of toothpaste today. Starting from the 1800s, tooth powders were gradually replaced by the kind of toothpaste that we are familiar with. Early toothpaste included soap or chalk. Colgate, one of the most popular brands today, first sold toothpaste in jars in 1873.
數千年來，不同文化使用不同的成分製作其牙粉跟牙膏，例如壓碎的樹皮、牡蠣殼、白堊和木炭。木炭依舊是現今特定牙膏品牌的常見成分。從 1800 年代起，牙粉逐漸被我們熟悉的那種牙膏所取代。早期的牙膏包含了肥皂或白堊。現今最受歡迎的品牌之一高露潔，在 1873 年首次販售罐裝牙膏。
