Teeth whiteners help lighten discolouration on the enamel's surface and can penetrate deeper into the tooth to eliminate intrinsic discolouration. If you want your results to last, Nevada, pay close attention to the ingredients and the type of product you're using.

"the key Ingredients to teeth whitening solutions that genuinely whiten tooth enamel colour is peroxide based, either carbamide peroxide or hydrogen peroxide." When applied to teeth, "these substances penetrate the enamel to reverse intrinsic [internal] and extrinsic [external] stains."

That is to say, and if you want a treatment that lasts, you should go with one that uses peroxide. She says that the concentration, duration, and delivery mechanism of peroxide-based whitening treatments are crucial in determining their efficacy.

The SmileDirectClub Teeth Whitening Kit

We tried twenty-one teeth whiteners and settled on SmileDirectClub's whitening kit as the clear winner. After using it for just one week, our tester saw a significant difference in the colour of his teeth without experiencing increased sensitivity.

Our tester, who has had professional teeth whitening and previously used gel-based whitening products, was pleasantly surprised to find that the SmileDirectClub Teeth Whitening Kit caused no pain throughout the whitening procedure.

Previously, she had mistakenly equated efficiency with discomfort and was relieved to learn that this was not always the case. The tester reported no pain when using the kit's LED light equipment and whitening gel.

Dental Teeth Whitening Strips

Because of their user-friendliness, whitening strips are among the most popular options for brightening teeth, but we're all too aware of the strips' tendency to slide around on the teeth.

With the whitening strips from Spotlight Oral Care, you can avoid that problem and get great results. "The product sticks to both the front and back of my teeth effectively—it has a vacuum-sealed effect," observed our tester, praising the strips' effectiveness and comfort.

After finishing the tests, our tester saw a change of five hues, with no tingling or discomfort. Our reviewer's sole complaint was that using the strips takes an hour out of each day.

Teeth-Whitening Kit Auraglow Deluxe

Whiten your teeth in as little as 30 minutes each session over a week with a portable LED device and Auraglow's Deluxe Teeth Whitening Kit. Our tester discovered that after using the gadget for the recommended period, their teeth were up to ten shades whiter.

The item itself was to blame for two of our tester's complaints. Regular users will notice that the tray is too big for their lips, and the gadget will need to be charged once a week even though it won't alert you that the battery is becoming low.

Whitening Pen From Auraglow

Teeth whitening pens are a convenient option for instant results and touch-ups. More than 20 treatments are included in the Auraglow Teeth Whitening Pen's convenient brush applicator.

The pen didn't wow our reviewer as much as others on our list, but they still believed it was useful as a portable option. They mentioned things like, "This product is simple and uncomplicated." "It doesn't take much time—literally 60 seconds—and it's easy to bring with you while you're travelling."

Teeth Whitening Trays, Opalescence Go, Prefilled

In between white strips and an LED gadget, a whitening tray may provide a more comfortable and, in some cases, more effective alternative.

You'll see results more quickly with the Opalescence Go Prefilled Trays since they employ a concentration of hydrogen peroxide that's 15% greater than some of the other alternatives on our list.

Although the greater dose produced considerable discomfort and sensitivity, our tester noted effects practically immediately after using it. While Opalescence's high-concentration formulation worked well for our lab's testing, the company also offers a 10% hydrogen peroxide formulation for their trays.

Sensitive Crest 3D Whitestrips

Intense bleaching might cause teeth to become more sensitive, which is a major worry for those considering it. Tooth sensitivity is a common complaint among patients who have had professional teeth whitening.

"Whitening... momentarily dehydrates the tooth," she adds. Peroxide "may permeate through the enamel to the dentin layer of the tooth and irritate the pulp (nerve) of the tooth," thus "whitening can also create tooth sensitivity."

Although tooth sensitivity is a common side effect of teeth whitening procedures, there are solutions on the market that are specifically meant to reduce sensitivity, such as the Crest 3D Whitestrips that we used for our test.
