At-home teeth whitening kits are a more reasonable, time-sensitive way to make your teeth shimmer. Crest's 3D Whitestrips lead the pack in this regard: They're a comfortable, straightforward, and fairly affordable pick, landing them a spot on our list of the best teeth whitening kits. 

This Black Friday, shoppers can pick up a 44-pack (22 treatments) of Crest Whitestrips for just $30, which is a 35% discount from their normal price. This deal is only $2 more than the lowest price we've ever seen them go for. 

Although Crest's Whitestrips recommend 20 days of use on the package, they also suggest that you'll start seeing results in as soon as three days. In our experience, results are pretty quick and last several months.

How do Crest 3D Whitestrips work? 

If you've not used Crest 3D Whitestrips before (or any teeth whitening kit), they work by lifting stains via literal strips you put on your teeth.

Each strip is coated in a whitening gel and the strips are intended to stay on your teeth for up to one hour to work fully. The strips are easy on your enamel, too, and don't usually increase sensitivity — though anyone with highly-sensitive teeth does run the risk of feeling some sensitivity while using these.

Don't just take our word for how well they work, either, as orthodontists also praise Crest's 3D Whitestrips, calling them one of the most effective and affordable whitening products you can use. And when they're on sale, that affordability gets even better. 

Do teeth whitening kits actually work? 

Yes, teeth whitening kits like the Crest 3D Whitestrips absolutely do work. Many people may see progress in as little as one use, though it's better to use the kits over their recommended timeframe to see the best benefits as possible. 

Though 3D Whitestrips may not always be as effective as professional whitening, orthodontists still view them as an effective and affordable alternative. 

Will Crest Whitestrips hurt my teeth? 

Though it's impossible to say for certain that they won't hurt every single user, Crest 3D Whitestrips are safe on tooth enamel and won't increase sensitivity. So long as they're used correctly, these are completely safe to use. 

If you're unsure of how safe they are to use, or have pre-existing dental conditions, consult your dentist prior to use. 

Can I still use these if I have sensitive teeth?

Yes, you can use Crest 3D Whitestrips if you have sensitive teeth. Do keep in mind, however, that while the strips themselves aren't supposed to increase sensitivity, those with highly sensitive teeth may experience it while using these strips. 

Consult your dentist prior to use if you have highly sensitive teeth.
