Some people don’t put much thought into their toothpaste selection, but there are different factors that differentiate certain products from others. Abrasivity is one thing to consider when looking at various options. Here’s how this factor can impact your teeth cleaning needs.

How Is Toothpaste Abrasivity Beneficial?

Abrasivity describes the number of abrasives present in toothpaste. These include materials, like hydrated silica and calcium carbonate, that are helpful in removing plaque and tartar from teeth and gums. These substances are major contributors to tooth decay and gum disease, so wearing away at them can improve your overall oral health. They may also help remove stains from the enamel and whiten teeth.

What Happens When Abrasivity Is Too High?

These abrasives don’t only target plaque and tartar; if too many are present, they may scratch against the tooth enamel and gums. This can lead to tooth sensitivity when exposed to extreme hot or cold foods, as well as gum irritation and inflammation. While these concerns aren't typically an issue with commercially-available toothpaste, people with tooth sensitivity may want to look for options with low abrasivity.

What’s the Proper Level of Abrasivity?

Toothpaste abrasivity is measured using a scale called relative dentin abrasivity (RDA). The American Dental Association recommends an RDA rating of 250 or lower. Products with this rating have been deemed safe for lifetime use without causing tooth and gum issues. Modern toothpaste formulas generally fall well below this level.
