Toothpaste: Paste or gel dentifrice used to clean and maintain the health of teeth

This substance has several purposes, such as removing plaque from one's teeth, whitening one's teeth and freshening one's breath.

Several toothpaste brands specialize in caring for teeth sensitive to certain conditions (for example heat, cold) or flavours (such as sweetness). The majority of these products work by strengthening the tooth enamel, thus easing discomfort and providing the teeth with a protective outer layer.

Traditionally, toothpaste has a minty flavour, as this is said to allow a sense of freshness in the mouth. However, fruit and flavours have been popular in the past. Fruit toothpastes, however, are discouraged by dentists due to their acidic and tooth-eroding properties.

Swallowing big amounts of toothpaste can make humans very sick and is poisonous. Due to this, the FDA started making toothpaste companies to put a notice about swallowing from 1997 to present.
