In a truly perfect world, brushing, flossing, and the occasional trip to the dentist are the ticket to permanently sparkling white teeth. Unfortunately, basic dental hygiene usually isn't enough to get the megawatt smile of your dreams. For that, you'll need to step up your game, and we've got just the thing: Crest Whitening Emulsions.

Crest Whitening Emulsions are a leave-on treatment that can remove stains from wine, juice and, of course, coffee. Don't confuse these Emulsions for Crest Whitestrips (which are also great, for the record) — these take literally seconds to apply, so you can swipe them on right before you have to run out the door, or even while on the go.

It's wickedly simple, too: Just squeeze the tube the way you would toothpaste, but directly on your teeth. The built-in applicator means you don't have to use your fingers or a brush, and the emulsion sinks in really quickly, so you aren't left with a film or nasty aftertaste.

The magic is in the formula: It's packed with peroxide droplets, which are both super effective while still being gentle enough for sensitive smiles.

This set comes with two pens, and here's the best part: They're on sale! Each pen lasts forever, so you can either keep the second pen as a backup or drop it into the stocking of a coffee-obsessed family member (they won't be offended once they see the results).

Over 1,100 five-star reviewers have raved about the emulsions. "I am obsessed!" shared a happy shopper. "The taste is minty, [and it] doesn't taste horrendous. The effectiveness and ease are wonderful. I saw a difference after one use!!!"

They're ridiculously easy to use. (Photo: Amazon)

One java lover added: "Wow — just wow! Finally, a product that actually works! I drink coffee every day, so my teeth were starting to look super yellow. I’ve been using this product for three days, and my teeth are white! You can see the results right away. Definitely earned the five stars."

This customer even swore that she won't ever even try another whitening product! "I love this teeth whitening product. It works super fast and does not taste like peroxide, like many do. The consistency is more like petroleum jelly, so [it's] thick enough to stay in place. No aftertaste, no odd feelings. Plus, my teeth look so white. I will not use anything else from now on."

Grab it now at this very, um, toothsome price.
