Chemicals In Toothpaste
Toothpaste helps prevent plaque and improves cosmetic functions.

SINGAPORE: Oral hygiene has two important functions - prevent plaque and improves cosmetic functions. There were many methods used in the past to keep the teeth clean. Some ancient people chewed on frayed twigs, while others rubbed their teeth with cloth or swabbed them in vinegar. The ancient Egyptians were the first to use toothpaste that was mixed with powdered pumice (a porous rock formed in volcanic eruptions) with vinegar and applied it to their teeth. Even today, some toothpaste contains pumice, but has many added ingredients to it.

Toothpaste contains several different necessary ingredients. A binder holds the other liquids and solid ingredients together. The most commonly used binders are sodium alginate and magnesium aluminum silicate. This affects the appearance of the paste.

The foaming of the toothpaste is due to the presence of foaming compound (sudsier). This helps clean particles on the teeth. Sodium lauryl sulfate is the most commonly used sudsier. Toothpaste also contains abrasives that help to clean teeth by removing plaque, stains, polish teeth and most importantly getting rid of those nasty remnants of the food. The most common abrasives that are used in toothpastes include hydrated silica, aluminium oxides, and calcium carbonate, different phosphates of calcium or aluminium. Apart from binders and abrasives, it also contains humectants and flavouring agents. Humectants keeps the toothpaste moist where as flavouring agents gives it a particular flavour, such as mint or cinnamon.

Fluoride is a final ingredient that almost every toothpaste has, with sodium fluoride being the most common. Water is also used in the final production process, as well as a preservative which protects the toothpaste from developing bacteria. Sodium benzoate is a preservative often used.

Some toothpaste contain desensitizing agents to reduce the sensitivity of tooth surfaces below the gum line. Others also contain a bleaching agent that may make teeth look whiter.
