It seems that purple is a very powerful color! We know purple shampoo is a thing to help tone your hair, but now it seems that purple toothpaste has been created to make your teeth whiter!
A brand of toothpaste by the name of "Popwhite" makes purple toothpastes and mouthwashes that can apparently whiten your teeth without the use of peroxide. This might be a good thing because it is said that peroxide could possibly weaken your enamel. So this new toothpaste - which works just like purple shampoo - could minimize the yellow tones in your teeth and leave you with a brighter, whiter smile!
