How Abrasive is Your Toothpaste?

aggressive-brushingThere are abrasives in most whitening toothpastes. Abrasives scrub stains away similar to the way you would scrub a dish clean. But high-abrasive toothpastes can wear away the enamel on your teeth over time. This can expose the softer layer of dentin underneath, leading to dentin sensitivity, also called tooth sensitivity.

Many whitening toothpastes also contain chemicals that remove surface stains from your teeth. Some whitening toothpastes also contain ingredients that bleach your teeth every time you use them.

If you are among the tens of millions of American adults who suffer from sensitive teeth, you don’t have to choose between sensitivity relief and whiter teeth. Look for a toothpaste with low-abrasivity that also offers whitening. Pick a solution that will clean and protect your teeth from sensitivity.  Check below to see where your toothpaste ranks.

In addition to picking the right toothpaste, it is important to remember to not brush too hard, as that can also wear down the enamel on your teeth, causing tooth sensitivity.  Select a soft bristled toothbrush, and be aware of how much pressure you use to brush.  Better yet, try an electric tooth brush, such as the Sonicare FlexCare Platinum, that has a pressure sensor that let’s you know when you’re brushing too hard.

If you’re not sure which toothpaste or tooth brush is best for you, you can call our office to discuss your options, or ask one of our doctors or hygienists next time you’re in the office.

Relative dentin abrasivity (RDA) is a measurement of the abrasive effect that the components of the toothpaste have on the tooth, particularly on enamel and dentin.  The higher the RDA value, the more abrasive the toothpaste.
