Scroll for some details — along with another excellent option for at-home whitening, also on sale.

Why is it a good deal?

If you're someone who keeps an eye out for these babies to go on sale (like we do), you know they're hardly ever discounted unless it's a big savings event, like Prime Day. And speaking of which, they're currently at their Prime Day price, so you know it's a good opportunity to snap 'em up! Plus, you can't beat a respected brand like Crest when it comes to at-home whitening.

Why do I need this?

The Crest 3D Whitestrips Professional Effects Plus kit is one of the most sought-after tooth-whitening treatments on Amazon due to its pro-level smile brightening effects. It also purports to remove up to 25 years of teeth stains without having a negative impact on your enamel.

This pack comes with 20 Professional Effects treatments, with one upper and one lower strip for each sesh. With the new "advanced seal technology," these strips no longer slip, so you can drink water — and even talk — while using them. Just peel a strip off, apply it over your teeth, leave it for about 30-45 minutes and voila! You'll start to notice a whiter smile in as little as three days, with the full effect taking place in about 20. You'll also get four treatments' worth of 1 Hour Express strips to use on days when you want same-day brightness.

What reviewers say:

"Great whitening strips!" exclaimed a happy shopper. "They got my teeth white or significantly lighter in one week! I feel confident about my teeth again! My teeth were sensitive the second day of use, but sensitivity was gone the next day and didn’t come back."

"This has done wonders for whitening up my teeth," raved another Crest convert. "I have tried the whitening pens and the blue light trays; however, the strips work a lot better. I’m an avid coffee and tea drinker. Will continue to use."

"These strips work," wrote a final fan. "Just gotta stay consistent and follow instructions. Great alternative to expensive dentist visits and far more convenient."

You can also save on this Crest 3D Whitestrips with Light kit:

These whitestrips will tackle stubborn stains with the power of light, helping to create results that last up to 36 months.

Got stubborn stains? The Crest 3D White Whitestrips with Light removes longtime coffee, wine and other stains on your chompers by combining whitening strips with the power of light. This kit includes 20 Whitestrips and a specialized handheld light. Like the 3D White Dental Whitening Kit, this is easy to use, safe and effective.

"Totally worked and was worth the extra cost to get it done in a week as opposed to the month treatment of the cheaper kit," a five-star fan said. "I only did seven days, and my teeth were significantly whiter."

If you have Amazon Prime, you’ll get free shipping, of course. Not yet a member? No problem. You can sign up for your free 30-day trial here. (And by the way, those without Prime still get free shipping on orders of $25 or more.)
