Toothpaste is a paste or gel dentifrice used with a toothbrush to clean and maintain the aesthetics and health of teeth. It is made up of a complex composition of various ingredients, including:
-
Abrasives: These substances help remove dental plaque and food from the teeth. The most commonly used abrasive in toothpaste is calcium carbonate, while other types of abrasives may include dehydrated silica gels, hydrated aluminum oxides, magnesium carbonate, sodium bicarbonate (baking soda), and more.
-
Fluoride: This naturally occurring mineral helps prevent tooth decay by promoting the remineralization of enamel, the outer layer of the teeth. Toothpaste may contain sodium fluoride, sodium monofluorophosphate, or stannous fluoride as recognized forms of fluoride by the Food and Drug Administration for cavity prevention.
-
Detergents: These ingredients help create foam and aid in the cleaning process. Common detergents found in toothpaste include sodium lauryl sulfate and sodium N-lauroyl sarcosinate.
-
Humectants: These substances help keep toothpaste from drying out, give it a consistent texture, and help it glide smoothly from the tube. Glycerol, glycerin, or glycerine are examples of humectants used in toothpaste.
-
Flavoring agents: These ingredients are added to improve the taste of toothpaste and make it more pleasant to use. Common flavoring agents include artificial sweeteners, such as saccharin or sorbitol, and natural flavors, such as mint or cinnamon.
-
Thickening agents: These substances help give toothpaste its desired consistency. Examples of thickening agents used in toothpaste include carrageenan, cellulose gum, or xanthan gum.
-
Preservatives: These ingredients help prevent the growth of bacteria and fungi in toothpaste, ensuring its shelf life and safety for use. Common preservatives include sodium benzoate or potassium sorbate.
-
Water: Toothpaste contains water as a base ingredient, which helps in the formulation and consistency of the product.
