- Tooth decay is caused by acids. - To combat acidity, a basic substance is needed. - Toothpastes typically contain mild bases like calcium carbonate or sodium bicarbonate, or other alkaline agents. - Fluoride compounds are also added to toothpaste to help remineralize enamel and make it more resistant to acid attacks, but the base component is for acid neutralization.
To protect tooth decay we are advised to brush our teeth regularly. The nature of the toothpaste commonly used is
