A Revealing New Study About Whitening Toothpastes

A Revealing New Study About Whitening Toothpastes

Today, there is a whole section in the oral care department at local drugstores devoted to teeth whitening, giving you many options to choose from if you want to address staining at home without visiting a dentist. 

One of the most popular types of whitening products apart from teeth whitening gel is whitening toothpastes. For years, dentists have been cautioning patients that some whitening toothpastes are actually hazardous to the dental enamel because they contain ingredients that can cause scratches. Now, there is a new study that suggests that using these products may not even do much good for people with stained teeth.

About the Study

This new study into the benefits of whitening toothpastes was conducted by a team of six scientists. The study was published in the November and December 2015 edition of the peer-reviewed medical journal General Dentistry, which is produced by the Academy of General Dentistry and is well regarded as a leader in the field of dental research.

What the Study Involved

The scientific team behind the General Dentistry study wanted to see how well whitening toothpastes performed when compared to conventional toothpastes at eliminating stains. For the tests, the team used one regular toothpaste, two toothpastes that contained phosphate salts to remove stains with friction and one toothpaste that included phosphate salts and hydrogen peroxide to address staining with friction and chemicals.

The test was performed on 60 samples of dentin, the bony portion of human teeth. To recreate natural staining, the teeth were dipped into a primer and black tea and left submerged for 60 minutes a total of 15 times. Then, the teeth were brushed using a conventional toothbrush and one of the four toothpastes. Photographs were taken and then analyzed for color and brightness.

Scientists found that all four toothpastes made the teeth shinier and cleaner looking. This is what you'd expect from any toothpaste. What was surprising, though, was that none of the whitening toothpastes did a better job at removing any of the stains than the non-whitening toothpaste.

The Final Takeaway

The results of the General Dentistry study seem to indicate that whitening toothpaste is no more effective at addressing dental staining than a regular toothpaste regardless of whether or not it contains hydrogen peroxide. While it's possible that over time, the toothpastes may have slightly diminished staining, the results were nothing close to what's possible with whitening gels like the ones sold here at

So should you not use whitening toothpastes? Because of the risks associated with abrasive phosphate salts, you may want to steer clear of whitening toothpastes. If you do choose to use one, be sure to let your dentist know so that he or she can keep an eye out for any signs of damage.
