Many toothpastes will also include artificial sweeteners. The minty taste that you associate with toothpaste isn’t a natural flavor. Manufacturers add saccharin and other ingredients to make the taste of toothpaste better. Without it, the process of brushing your teeth wouldn’t feel as pleasant. If brushing your teeth left you with a bad taste in your mouth, it might reduce your desire to brush regularly. Toothpaste now comes in flavors as diverse as lemon, grape, and bubblegum to make them more appealing – not just for adults, but for children too.
Toothpaste also includes ingredients to keep the tube from drying out. Without the moisture retention of humectants, your mouth would dry too soon. These are the same ingredients that keep you from having dry skin. Finally, toothpaste uses thickeners to make sure that the actual substance maintains a gooey form.
