Though in-office visits can ensure a practically seamless whitening experience, it's not always convenient to schedule an appointment with your local dentist. When a professional appointment just isn't in the cards—or is simply out of budget—there are a number of effective at-home options from top brands like Crest and Auraglow that are worth the buy.

"I've dabbled with teeth whitening kits in my high school days that felt too complicated and daunting to use, but the new ones I've tested in the last few years are as easy to use as brushing my teeth," BAZAAR associate beauty editor Katie Intner notes. And while brightening your smile on your own may seem daunting at first, the best teeth whitening kits complete with pens, strips, and easy-fill trays make the process simple and painless.

"A moldable tray or strip that closely adheres to the teeth but won’t be too large to get on gum tissue should always included in a teeth whitening kit," cosmetic dentist Amanda Lewis tells BAZAAR.com. "Patients with more age usually have a thicker amount of inner tooth structure called dentine and that’s what whitening kits work on."

For those in search of an effective solution to a more luminous smile, the best whitening kits can be an ideal option for a more radiant smile. To help enhance your smile even faster, we've pulled together 15 coveted sets that dentists and beauty lovers alike are raving about

Frequently Asked Questions

What makes teeth look whiter?

When it comes to the natural shade of your teeth, a variety of genetic and lifestyle-based factors can directly impact their color. "Tooth color is a result of both the natural structure of teeth and the presence of stains on teeth. Stains typically come from external sources such as foods, drinks such as tea, coffee, and wine, tobacco use, and tartar," Venda Maloney, oral care early research director at Colgate-Palmolive, explains. "Over time, tooth color becomes darker due to continued exposure to stains as well as enamel wear."

A couple common chemicals used to whiten teeth include carbamide peroxide and hydrogen peroxide, which work in similar ways. Carbamide peroxide lasts longer when its in active form, but needs to be stronger than hydrogen peroxide to work well.

Are teeth whiteners safe to use?

Each ingredient is deemed safe and effective to use at lower percentages, but at higher percentages, they can cause gum tissue damage or an increase rate of tooth sensitivity.

Can I whiten my teeth if they're sensitive?

"One red flag to keep in mind with teeth whitening is increased sensitivity that doesn’t diminish after a 48-hour period," adds Lewis. "Another is gum irritation, as some people will have increased sensitivity, and will need to take more time in between whitening."

According to experts, whitening can temporarily dry out your teeth, which is ultimately what causes their sensitivity. As the teeth rehydrates, the sensitivity diminishes. "You should always visit a dentist prior to teeth whitening, because whitening in the presence of tooth decay is not advised," continues Lewis. "If you get a clean bill of health from your dentist and you have straight teeth, trying over-the-counter teeth whitening is a great option. If you don’t get the results, you want form those kits you should visit your dentist for stronger concentrations that can be applied safely."
