Judging by the sheer number of teeth-whitening products out there, it's never been an easier time to get a brighter smile without leaving your home. There are the traditional toothpastes, whitening trays and strips, and mouthwashes, but there are also newer, high-tech devices that use LED technology. And since there are so many options to choose from, it can be hard to figure out the right one for you, and one that actually works.

The last thing you want to do is shell out money for something that doesn't work at all or that somehow ruins your teeth. To help, we did a little investigating and asked Michaela Tozzi, DMD, for tips on what to look for in teeth-whitening products.

First things first, Tozzi broke down the kinds of products on the market. "There are two main types of bleaching systems on the market," she explains. "The biggest difference between the two is that one system utilizes a light to activate the whitening gel and one does not. There are also pastes, mouthwashes, etc."

When shopping for a product, Tozzi says the priority here should be safety and efficacy. You can do that by reading reviews and doing your own research. It might also help to chat with your dentist about the options available.

While the type of treatment mostly depends on personal preference, Tozzi recommends staying away from anything that is too abrasive. "For example, charcoal-based whitening pastes can destroy precious enamel leading to sensitivity," she explains. "If they are used for an extended period of time, they can cause the teeth to appear more yellow."

And don't forget to study the ingredient labels carefully. Tozzi says you should steer clear of products that don't have ingredient transparency. The two most common active ingredients in whitening treatments are carbamide peroxide and hydrogen peroxide.

It's important to note that not everyone's smile is suited for at-home teeth whitening. For some people, it might cause more damage than good. "Patients with active decay or periodontal problems may want to avoid at-home whitening treatments, as it can cause extreme sensitivity in these cases," Tozzi says. Overall, it would be best to check with your dentist before using a kit to avoid any future dental problems.

If you can go the at-home route, it's important to follow the product's specific directions, and pay attention to any side effects or reactions. While you can use the product as often as you like—or as recommended by the manufacturer—Tozzi says she advises her patients to use them less frequently once the color they want, or if they are experiencing any teeth or gum sensitivity.

And keep in mind that it's all about moderation. "So many patients like to think that a little whitening gel is good, but excess whitening gel is better," Tozzi explains. "Too much whitening gel can ooze over the gum tissue and cause a chemical burn on your gums (ouch!). If you notice that your gums are white and sensitive after the whitening treatment, the gums were burned. This would indicate that too much gel was applied, or the gel was left in the mouth for too long."

Products aside, in general, if you want to keep your teeth white, you'll want to make sure you're visiting the dentist for regular teeth cleanings and checkups. And for every day, keep a reusable straw with you. 

"If you drink coffee, tea, or red wine, drink through a straw to limit the contact with the teeth, Tozzi suggests. "If this doesn't sound enjoyable, rinse with water once you're done imbibing. A mild whitening toothpaste like Klen is great to use on a daily basis to minimize surface stains."

Strips, Trays, and Pens

Crest's Whitestrips are probably the most popular at-home whitening kit out there—and Tozzi says they are tried and true. They have a no-slip grip so you can talk and drink water while you're wearing them. They've also got the approval of the American Dental Association.

Opalescence's whitening trays are another recommendation by Tozzi. I can also vouch for them, as I've been using this bleaching gel for years. You'll need to get a custom tray made for you at your dentist's office, and all you have to do is apply the gel to the tray and let it work its magic. I find that I only have to use them once a month for upkeep.

This pen makes it easy to whiten your teeth pretty much anymore. Made with 35% carbamide peroxide, apply the pen to teeth, smile for 60 seconds, and that's it. Make sure you don't eat or drink for an hour after application.

These strips contain coconut oil, lemon peel oil, sage oil, and Dead Sea salt for a gentler whitening experience. The treatment only takes 30 minutes.
