Best Drugstore Teeth Whitener
A simple yet effective solution, swap out your regular toothpaste with one that has whitening ingredients. But remember to use it every time you brush your teeth, or you're unlikely to see the necessary results. We like this 2-in-1 kit by Colgate as it comes with whitening toothpaste, new toothbrush, and a built-in whitening pen. You will see results on your teeth within days!
