Crest 3D White Whitestrips 1 Hour Express Teeth Whitening Kit, 7 Treatments

I've tried many different brands of whitening products but this by far gives the most consistent, long-lasting result. Granted, it can make your teeth a little sensitive but my teeth are always noticeably whiter after one use. This will always be my go-to repurchase.

I bought the Crest Whitestrips Duo Bundle because apparently “coffee teeth chic” isn't in style anymore. Within a week, my teeth were so bright my Zoom camera kept auto-adjusting like I was the sun. My dentist said, “Wow,” my friends said, “Who are you trying to impress?” and my dog refused to make eye contact because the glare was too much. The “Perfect Duo” part is legit—it whitens your teeth and your self-esteem at the same time. Bonus: when I smiled at my neighbor, they tripped on the sidewalk. Do I feel bad? Yes. Am I still smiling? Also yes. Warning: you will start judging everyone else's teeth. It's a side effect. 10/10. My only complaint is that I can't sneak snacks at night anymore—my teeth light up the kitchen like motion-sensor lamps.
