The best teeth whiteners come in an array of designs, including teeth whitening kits, whitening toothpastes, and strips applied directly to your upper and lower teeth. They aren’t expensive, but they can make a big difference when keeping your smile brighter in between trips to the dentist.

When choosing from among the best teeth whiteners there are a few things to keep in mind. Firstly, do you want to use only natural ingredients? If so, that will narrow the amount of teeth whitening kits available to you. Many of the formulas use the same active ingredients, such as hydrogen peroxide, used by dentists. These are safe for most people, but if you’re pregnant or breastfeeding, choose natural ingredients.

Are you prepared to get a little messy in the bathroom? Then you can take your pick of the best teeth whiteners that use gels, serums and powders. Many of the best electric toothbrushes also have whitening modes, but adding in a whitening toothpaste or strips can reduce more of the stubborn stains that your toothbrush can’t lift alone.

There are many things that stain teeth, including red wine, coffee and even fruit juices, but most smiles can be whitened at home without the hassle or cost of whitening treatments at the dentist. It’s also worth bearing in mind that even the best dental insurance doesn’t cover teeth whitening, so the cost falls to you.

Luckily, there are many ways to whiten your teeth at home. Some of the best teeth whiteners also come with LED lights to boost the active ingredients found in the paste and brighten your teeth quicker. Let’s take a look at these now…

Included in the box is an enamel-friendly whitening gel made with the same hydrogen peroxide ingredient used by dentists. This sits in the mouth tray, which fits over the teeth for five minutes (or longer if the teeth are very stained) and ensures the gel is evenly applied on your teeth, including in-between those nooks and crannies. 

There’s also a bottle of Plus White’s Stainguard Post Rinse, which helps lock in your new whiteness and prevents stains from reappearing. The results with Plus White’s teeth-whitening system are apparent from the get-go, making this the best teeth whitener for when you need to show your smile at a moment (or five)’s notice.

The Cali White Deluxe Teeth Whitening Kit comes with plenty of bits and pieces including an LED light with built-in timer to boost the whitening results, two 5ml gel syringes, two mouthpiece trays, and a patented Universal Comfort Fit tray made with a safe and clean medical-grade silicone. 

The tray also has a gum-safe design with easy-breathe ventilation. There’s also a travel case (with cool palm tree design, no less) to store the mouth trays in. Natural ingredients in the gel include xylitol and organic peppermint oil.

Device needs charging

Colgate gets top grades all round with its Optic White Kit. It takes just ten minutes’ use daily for ten days to get the same long-lasting white smile you’d get at the dentist. It’s also designed to rid you of up to ten years’ staining on your teeth. That’s impressive.

Used together with Colgate’s blue-light whitening device, the 9% hydrogen peroxide whitening gel can make teeth six shades whiter while also lifting stains faster.

True to Colgate form, the easy-to-control serum has a pleasant taste and offers a natural level of whiteness without causing extra sensitivity. There are no fiddly trays to mess around with either: simply dispense the serum into the gadget, place it on your teeth, then wait while the gadget does its thing.

Lumineux Oral Essentials Teeth Whitening Strips

Get a brighter smile without all the chemicals

Type: Strips | In the box: 28 strips | Number of uses: 14 treatments

Sugar-free
All-natural ingredients
Fuss-free and portable
Strips don’t always fit snugly

With ingredients straight from mother nature, Lumineux promises a whiter smile in just seven days. This set of sugar-free vegan teeth-whitening strips is ideal for sensitive teeth, and uses non-toxic ingredients.

These include coconut oil, lemon peel oil and sage oil to remove stains from teeth, rather than rely on the peroxide chemicals found in some other teeth whitening treatments. The strips also contain Dead Sea salt to help reduce sensitivity to hot or cold liquids. 

Lumineux’s teeth whitening strips are safe to use with most porcelain, caps, crowns and veneers, and are incredibly straightforward too. Just select an upper and lower strip, remove the backing, apply to the teeth and wait 30 minutes before removing the strips. It’s as easy as that. 

Because Lumineux’s teeth whitening strips are so portable and fuss-free, it also makes them the best teeth whiteners to take away overnight or on vacation.

Active Wow Teeth Whitening Charcoal Powder

Go back to basics with this all-natural powder

Type: Powder | In the box: One jar of coconut-charcoal powder | Number of uses: 100

All-natural
Good for sensitive teeth
Gets messy when brushing
Results not as quick

If you prefer to keep your wellness products all-natural, Active Wow’s 24k White Teeth Whitening Charcoal Powder is the perfect choice. Free from chemicals, artificial flavors and colors, it works from the get-go to make your teeth whiter without any sensitivity. 

The activated coconut charcoal not only whitens teeth, but detoxifies the mouth to freshen breath and gently polish away stains. This economical powder can last up to a 100 uses and it’s easy to use too. Simply wet your toothbrush, dip it in the powder, and gently brush your teeth for one to two minutes before rinsing thoroughly. Use once or twice a day.

Admittedly, this teeth-whitening solution won’t be for everybody, as it can get a little messy and you have to rinse thoroughly. Also, it isn’t as fast acting as the other kits in our best teeth whiteners guide, but it’s ideal if you want to take your teeth-whitening regime back to basics and go chemical free.


9. HiSmile: Best teeth whitener for sensitive gums

A teeth whitening kit loved by celebrities

Expensive

Popular among celebrities and social media influences, the HiSmile kit is similar in form factor to many at-home whitening products, with an activator LED, trays and syringes full of whitening gel. 

Unlike others that contain dental-grade peroxide, however, the HiSmile whitening gel relies on ingredients like sodium bicarbonate (baking soda), sodium chlorite and plant extracts. Without the harsher chemicals, the HiSmile system also is less likely to cause tooth sensitivity or gum irritation. It’s also vegan friendly.

The Rembrandt 1-Week Whitening Kit packs two weeks' worth of treatments into half the time, giving you faster results than many other teeth whitening kits. The biggest difference between this and others featured in our best teeth whiteners kit is that the Rembrandt strips are designed to be used safely twice a day. 

The box contains 28 enamel-friendly hydrogen peroxide strips. Rembrandt’s kit has generous strip proportions, especially for the lower-teeth. Larger strips fit more comfortably and stay on better than other kits with smaller strips, with the added advantage of whitening both the front and back of your teeth.

Dr Song's best teeth whitening kit comes with extra goodies to help protect your teeth from sensitivity or irritation. While most tray and syringe-type kits only include the whitening gel, a teeth tray and maybe an accelerator light, the Dr Song kit adds two syringes of remineralization gel and Vitamin E swabs for your gums. 

The remineralization gel gives your enamel a boost of fluoride and calcium after your whitening treatments, and the Vitamin E swabs help protect your gums from potentially-irritating exposure to the whitening gel.

Burst also makes it supremely easy to upkeep your smile with a convenient, discounted subscription program that sends you one or two packs of strips every three months and saves you $5 per box.
