Toothpaste is not always paste. It can be a gel, powder, or paste that you brush onto your teeth and gums to help get rid of accumulating plaque and improve your oral health. According to the American Dental Association (ADA), toothpaste is important to oral health because it helps to remove plaque and its bacterial buildup on teeth and fights off periodontal (gum) disease. Most toothpaste also contains fluoride, which bolsters tooth enamel and fights tooth decay.
What’s in Toothpaste?
The exact composition of different toothpastes may vary slightly depending on the benefits being touted by the particular brand (such as whitening teeth or reducing gum inflammation). In general, toothpastes include the following ingredients:
- Gentle abrasives, such as magnesium carbonate, dehydrated silica gels, calcium carbonate, hydrated aluminum oxides, and phosphate salts.
- Glycerol, sorbitol, or other so-called “humectants,” substances that keep the toothpaste from drying out.
- Thickeners like seaweed or mineral colloids, synthetic cellulose, or natural gum to give the toothpaste a homogeneous appearance and texture.
- Fluoride to help make tooth enamel stronger and more resistant to decay.
- Flavoring agents that do not cause tooth decay, such as saccharin.
- Detergents, such as sodium lauryl sarcosinate, to make the toothpaste foamy.
