Toothpaste
Toothpaste
Toothpaste (/tuːθpeɪst/) is a gel or paste used in conjunction with a toothbrush to clean and maintain the health of teeth. Toothpaste is used to promote oral hygiene by removing dental plaque and food particles, suppressing halitosis, and delivering active ingredients such as fluoride to prevent tooth and gum disease.
Etymology
The term "toothpaste" is derived from the words "tooth" and "paste," indicating its primary function and form. The word "tooth" comes from the Old English "tōþ," while "paste" originates from the Latin "pasta," meaning "dough, pastry cake, paste."
Composition
Toothpaste is typically composed of several ingredients. These include:
- Fluoride: A mineral that helps to prevent tooth decay by strengthening the tooth enamel.
- Abrasives: Substances such as calcium carbonate or silicates that help to remove plaque and stains from the teeth.
- Humectants: Ingredients like glycerol that keep the toothpaste from drying out.
- Detergents: Such as sodium lauryl sulfate, which creates the foaming action of toothpaste.
- Flavoring agents: Such as saccharin or sorbitol, which give toothpaste its taste.
Types of Toothpaste
There are several types of toothpaste available, each designed to address specific oral health concerns. These include:
- Whitening Toothpaste: Contains additional or special abrasives to help remove stains and whiten teeth.
- Sensitive Teeth Toothpaste: Contains ingredients like potassium nitrate or strontium chloride to help reduce tooth sensitivity.
- Children's Toothpaste: Typically has a milder flavor and less fluoride than adult toothpastes.
Related Terms
- Dental Floss: A cord of thin filaments used to remove food and dental plaque from between teeth.
- Mouthwash: An antiseptic liquid used for rinsing the mouth and throat.
- Toothbrush: A tool with bristles, used with toothpaste to clean the teeth and gums.
