Is Whitening Toothpaste Safe for My Teeth?

Brushing with a whitening toothpaste can be a inexpensive and convenient way to brighten your smile over time, but you may wonder if it can simultaneously harm your teeth. Let’s take a look!

What is Whitening Toothpaste?

In additional to the mild abrasives and cavity-fighting ingredients found in regular toothpaste, a whitening toothpaste usually contains more abrasives and a very low dose of a bleaching agent. Gentle abrasives, such as calcium carbonate, magnesium carbonate, and hydrated aluminum oxides and silica, polish away surface stains. A small amount of a bleaching agent, like hydrogen peroxide or carbamide peroxide, is meant to slowly whiten teeth over time.

Can Whitening Toothpaste Damage My Teeth?

Like any toothpaste, the mild abrasives in a whitening toothpaste can erode your enamel if you consistently brush too vigorously and/or do not use a soft-bristled toothbrush. And although some whitening toothpastes may cause temporary tooth sensitivity, all toothpastes on the market are considered safe for teeth with proper brushing technique. Many people claim that a toothpaste with a Relative Dentin Abrasivity score (RDA) less than 70 is safer for your teeth than a toothpaste with a higher RDA value, such as a whitening toothpaste. However, the recognized safety threshold for toothpaste is an RDA value of 250; everything from 0-249 is considered safe if used correctly.

The American Dental Association (ADA) has stated: “Clinical evidence supports that lifetime use of proper brushing technique with a toothbrush and toothpaste at an RDA of 250 or less produces limited wear to dentin and virtually no wear to enamel… [RDA] should not be used to rank the safety of dentifrices with RDA values below 250.”

Does Whitening Toothpaste Work?

Most whitening toothpastes only remove surface stains from teeth instead of actually changing the color of enamel. The design and recommended use of whitening toothpastes just doesn’t allow them to deliver the same dramatic whitening effects as our professional ZOOM!® Teeth Whitening, available in-office or via custom take-home trays. Our whitening system will safely brighten your teeth up to eight shades in just one visit. You’ll be amazed at the results!
