How effective is citric acid in toothpaste for maintaining oral health and preventing cavities?

Citric acid in toothpaste can be effective for maintaining oral health and preventing cavities. It helps to break down plaque and bacteria on teeth, which can reduce the risk of cavities. However, citric acid can also erode tooth enamel if used in high concentrations, so it is important to use toothpaste with citric acid in moderation.
