Pearly white teeth never go out of style. However, if you don’t want to shell out hundreds for your dentist to whiten your chompers, you’ll need a great at-home teeth whitening kit. Fortunately, there are a ton of affordable teeth whitening products available on Amazon for under $50. In fact, there might be too many choices, which is why we’ve compiled a list of the best teeth whitening products on Amazon.
Keep reading to review the top-rated whitening kits, powders and strips designed for at-home use. Plus, we’ll break down how these home remedies work and what you should look for in a whitening product.
How Do Teeth Whitening Kits Work?
Teeth can and will get stained. It’s the sad truth. Harsher stuff such as coffee, wine and cigarettes will obviously speed up staining or discoloration, but everyday foods like balsamic vinegar, spaghetti sauce and fruits will also cause your teeth to lose their pearly whiteness as well.
For most people, brushing and flossing twice a day isn’t enough to fight yellow teeth. That’s where teeth whitening products come in. Teeth whiteners come in a variety of forms, from simple toothpastes to light-activated gels. They’re all effective means to whiten those fangs, but some are more intensive and some are simply easier to use. It all depends on your preferences.
Besides simple solutions such as toothpaste upgrades or whitening strips, there is a more serious option: teeth whitening kits. These kits typically use an LED lighted mouthpiece and a gel solution to whiten teeth. Basically, the LED light activates the main ingredient in the teeth whitening gel (carbamide peroxide). This means you don’t have to whiten as often, but the sessions for LED kits are slightly more work on top of regular brushing.
Here’s how it works: apply the gel to the LED mouthpiece, let it sit in your mouth for 15-30 minutes, and then brush away the excess gel after removing the mouthpiece. Do this once a day for a few days while streaming your favorite show, and enjoy whiter teeth in as little as a week.
You can also find whitening strips, which are applied directly to the upper and lower teeth, as well as charcoal-based powders that naturally absorb stain-causing contaminants.
Whether you want to try a serious whitening kit or you’re just looking for a simple toothpaste upgrade, we’re here to help. Below are some of the top-rated and best-selling teeth whitening products on Amazon. Keep reading to brighten your smile without hurting your wallet.
1. Active Wow Teeth Whitening Powder
This whitening powder toothpaste has stellar customer ratings with almost 20,000 Amazon customer reviews and 4.1 stars. The reasons for these rave reviews are pretty straightforward: the stuff really works and it’s super easy to use. It replaces your normal toothpaste and uses activated charcoal to deeply clean teeth, resulting in more pearly chompers after a single-use. Just be sure to spit carefully when you’re done brushing, as the powdery toothpaste is black and can be messy. If you can get over the odd sensation of applying black powder to turn your teeth white, this charcoal-based product is easily one of the best teeth whitening products on Amazon.
Pros: Simple, natural and very easy to use.
Cons: Can be messy and the black color can seem counterintuitive to first-time users.
2. Crest 3D Whitening Strips Kit
Crest’s whitening strips have become a hit because they’re easy to use and highly effective. Just put on the strips for an hour a day, and get a brighter smile in 3 days. Plus, the strips will stay on while you talk or drink water, so you can still function while you whiten.
Pros: Effective, very easy to use.
Cons: Most expensive product on this list. Like many teeth whitening kits, these strips can cause tooth sensitivity and mild pain.
3. AsaVea Teeth Whitening Pen
Peroxide-based pens are an affordable, easy way to remove teeth stains. These highly-rated pens from AsaVea use a carbamide peroxide to break down stains that your toothbrush just can’t reach. Before using the pen, be sure to brush, floss and dry your teeth with a tissue. Then turn the bottom of the pen until gel appears on the brush. Apply a thin layer to your teeth (not your gums or lips) and wait 30 seconds before relaxing your lips. Do this twice a day and enjoy whiter teeth in as little as a few days.
Pros: Quick, convenient, affordable and great for travel.
Cons: Not as effective on tough stains.
4. Cali White Activated Charcoal Toothpaste
Another easy way to whiten teeth is by swapping out your regular toothpaste for a quality activated charcoal toothpaste such as this one from Cali White. It uses natural ingredients including food-grade activated charcoal (active carbon), organic coconut oil and baking soda. This chemical-free formula offers one of the safest means of whitening teeth. Just don’t be afraid of the black color.
Pros: Natural, safe and no extra gear required.
Cons: Black color can seem strange at first.
5. Zero Glow Teeth Whitening Kit
If you have mild teeth stains — not yellowing caused by decades of coffee and cigarettes — this is a good at-home whitening kit. And at just $27, this product from Zero Glow is the most affordable kit on our list and has some impressive reviews to boot. It comes with the LED base, three mouthpieces and three carbamide peroxide syringes. The Zero Glow kit is great if you’re unsure about teeth whitening kits and don’t want to spend too much. It’s also good if you need some whitening ASAP, as just one session (20-30 minutes with the mouthpiece in) will yield whiter teeth.
Pros: Affordable, fast whitening.
Cons: No case for the mouthpieces. Carbamide peroxide be tough on sensitive teeth. Best for mild staining.
6. Cali White Teeth Whitening Kit
Another great whitening kit is this one from Cali White. It comes very highly-rated with over 4,000 reviews and includes a handy travel case (for, say, taking the kit to a destination wedding). This Cali kit can work in as little as 10 minutes, making it great if you’re too busy for a 30-minute session. Also, a handful of reviewers with sensitive teeth say the kit was gentle – probably thanks to a lower percentage peroxide gel.
Pros: Soft on sensitive teeth, works quickly.
Cons: Only includes two syringes of gel. Some users report whitening faded too quickly. Peroxide can cause tooth sensitivity and gum pain.
7. iSmile Teeth Whitening Kit
This teeth whitening kit from iSmile has a special trick: it uses your smartphone as a power source. Most other kits have batteries in the LED light, but this one plugs right into your phone. This means the mouthpiece is more streamlined, and you won’t have to replace any batteries. This kit also uses peroxide pens instead of syringes. Apply the gel to your teeth with the pen, and then insert the mouthpiece for 15 minutes.
Pros: Powered by your smartphone. Includes a desensitizing gel, which is ideal for users with sensitive teeth
Cons: Slightly pricey compared to budget options. Peroxide can cause tooth sensitivity and gum pain.
8. Active Wow Teeth Whitening Kit
Active Wow’s teeth whitening kit is another option worth considering. The kit offers the most bang for your buck with 35 treatments. Your teeth will get considerably whiter after just seven uses, so you can use the kit and then shelf it until need be. Active Wow’s kit also boasts the best reviews for any kit on our list with over 2,200 reviews and 4.1/5 stars.
Pros: Many uses from a single kit, nice minty flavor. Fast results.
Cons: Can cause mild gum pain. Replacement molding trays not sold separately if you need replacements.
9. Opalescence PF Teeth Whitening
If you run out of peroxide gel syringes, there’s no need to purchase a whole new kit. Instead, restock with these highly-rated syringes from Opalescence. They’re 35% carbamide peroxide and feature a minty flavor that reviewers love. One review comes from a dentist who notes that the gel in these syringes is good and sticky, as a peroxide gel should be in order to avoid dilution from saliva. The syringes also have a long shelf life (two years) so you can keep them handy for future whitening treatments.
Pros: Affordable restocking option; high viscosity.
Cons: Syringes only; requires an additional kit.
