How do whitening toothpastes actually work?

Typically slightly abrasive, most whitening toothpastes contain ingredients like silica that work to scrub the surface of the teeth, and deeply clean the outside layer. “Some also contain hydrogen peroxide and carbamide peroxide, which are bleaching agents,” adds Wilczynski. “Although these will be at a very low level compared to professional whitening products — so they're so safe for home use.” Activated charcoal is another popular scrubbing ingredient — but it isn't endorsed by all dental professionals, as it can be known to wear away enamel.

Some whitening toothpastes also contain the chemical ‘blue covarine’, which adheres to the surface of the teeth and creates an optical illusion that can make teeth appear less yellow. Others are boosted by enzymes that help to gently break down plaque and staining.

Whichever whitening technology you reach for, Wilczynski recommends always choosing a toothpaste containing fluoride: "It's the essential ingredient for protecting and fighting against tooth decay.”


Are they safe for your teeth?

Yes. The majority of shop-bought, FDA-approved whitening toothpastes offer gentle yet effective results and should be suitable for most. But the health of everyone's teeth and gums varies greatly, so it's always advisable to speak to your dentist before investing in any new at-home dental care.
