Is whitening toothpaste harmful for teeth?

Posted by info on December 11, 2014 at 8:50 AM

The reason the whitening toothpaste is called "Whitening" is because the paste is more abrasive than the non-whitening toothpastes. Toothpaste brands aren't legally allowed to put any chemical into the toothpaste, such as peroxide to lighten the teeth. The stain that the whitening toothpaste gets rid of is on the surface of the tooth usually caused by the food you eat. Because the whitening toothpaste is abrasive, it can wear down the enamel on your teeth if used daily, causing abrasion and sensitivity.

You may want to ask you Dental Hygienist the next time you go in for a cleaning,(or your dentist if you see him/her first)


You probably will not see a huge difference in the whiteness of your teeth unless you have heavy deposits of stain on your teeth. After you use the toothpaste it will stay white as long as the debre is gone. Things that cause stain on the outside of your teeth: coffee, coke, green tea, tea, smoking, corsodyl mouthmouth. If used enough, some of these stains can be absorbed into your teeth as well. Whitening toothpaste should only really be used once per week.

The only way to actually lighten the shade of the enamel is by chemically beaching the teeth. this is not harmful to the teeth and the results are always predictable. 

Tooth whitening is only legally allowed to be performed by a dental proffessional, please ask your dentist for more details.
