The Problem with Toothpaste

We spend 2.2 billion dollars on toothpaste in the United States. The number of choices on the shelves is mind-blowing, but what you don’t know, and the toothpaste companies don’t seem to care about, is the permanent tooth destruction toothpastes are causing. Toothpastes have abrasive particles usually containing hydrated silica. These particles can vary greatly in their abrasiveness. Toothpastes have abrasive ratings called “Relative Dentin Abrasivity” which can range from 8 to 200. Low abrasive toothpastes are considered to be less than 70, medium 70 to 100, high 100 to 150 and harmful greater than 150. If toothpaste is too abrasive, it will wear the enamel of your teeth regardless of the softness of your toothbrush. This usually causes sensitivity, staining, increased risk of cavities and weakening of the tooth. Ironically, some of the toothpastes marketed for sensitivity are too abrasive worsening the problem it’s claiming to correct. Further proof of toothpaste abrasivity can be seen by the other uses of toothpaste such as scrubbing grout in shower, linoleum scuffs, jewelry and crayon on walls just to name a few. Delmarva Dental Services recommends low abrasive toothpastes. You can find abrasivity values on our website. RDA = Relative Dentin Abrasivity See Video  “Toothpaste Too Abrasion”
