If you have blonde or lighter hair, you likely have already dabbled in the purple product trends. Purple shampoo is used to brighten our locks — and now, the same can be true for our teeth. Similar to the way the purple color in the shampoo keeps hair from looking yellow and brassy, purple serums and toothpastes can do the same. According to Women's Health, a popular toothpaste option is the Popwhite Purple Power Duo created by Pop White Smile. Ideal for those with sensitive teeth, this is a good option for a temporary brighter smile.

But if you want white teeth for longer, you may want to consider the Hismile V34 Color Corrector serum. Unlike toothpaste, this purple-based serum uses the purple hue to cancel out the yellow tint in your teeth. The product is water soluble, so you won't see any purple residue after rinsing. According to Dentaly, this is a great product, but is best used after a whitening treatment, either one done professionally or at home. Even still, people are loving the product — and taking to TikTok to let others know.
