Toothpaste abrasiveness is measured using the Relative Dentin Abrasivity (RDA) value, with a lower value indicating lower abrasiveness. Current scientific data suggests that any toothpaste with an RDA of 250 or below is safe for daily use
. The most common form of fluoride in toothpaste is sodium fluoride, which is recognized for cavity prevention by the FDA
. Some common abrasives in toothpaste include magnesium carbonate, silicates, phosphate salts, hydrated aluminum oxides, and dehydrated silica gels
. Sodium lauryl sulfate is used to create the foamy action in toothpaste but can cause mouth sores in some people
. The American Dental Association recommends using a toothpaste with a low RDA value, ideally in the 0-70 range, to minimize abrasiveness
. It is important to choose a toothpaste that meets your individual needs, such as sensitivity, whitening, enamel repair, or gum health
