If your pearly whites have lost their luster, you may want to consider teeth whitening. But with choices ranging from laser treatments to less expensive solutions you can apply at home, how do you choose the best option for you?

Do you hesitate before flashing your big, bright smile — because it’s not as bright as you’d like? You’re not alone: According to the American Academy of Cosmetic Dentistry, 96 percent of respondents surveyed believe an attractive smile makes a person more appealing. But if your discolored teeth are keeping you tight-lipped, you may want to consider teeth-whitening treatments.

According to Elisa Mello, DDS, a cosmetic dentist at NYC Smile Design in New York City, there are various options, both professional teeth whitening and drugstore solutions, to consider. But is one option better than the other?

The teeth-whitening option you choose will depend on your budget, the severity of your teeth discoloration, and how dramatic you want your results to be. Keep in mind — teeth that are yellow will probably lighten more than teeth with a brownish or grayish tinge.

Here’s how to choose the right tooth-whitening treatment for you.

Teeth-Whitening Option No. 1: Laser Bleaching at the Dentist’s Office

“With laser bleaching, a barrier is put around the gum tissue and a strong bleach is put on your teeth,” Dr. Mello says. “A laser light is used to activate the bleach and make it work.”

Because your gums are protected and you are under the supervision of your dentist during this professional teeth-whitening treatment, the bleach is a stronger solution than one you’d use on your own at home.

Laser teeth whitening can be performed in one office visit, generally with three 20-minute bleaching treatments. Dr. Mello calls it instant gratification — “In an hour, you are going to walk out with your teeth a lot brighter.” But this is the most expensive of the teeth-whitening options (see price estimates below).

Teeth-Whitening Option No. 2: Professional Bleaching Trays

Another professional teeth-whitening option your dentist may offer is bleaching trays. With this method, your dentist will use an impression of your teeth to design custom bleaching trays that perfectly fit your teeth. At home, you’ll use a special bleaching solution in these trays daily for one to two weeks. According to Mello, bleaching trays can be used in addition to dentist office laser bleaching when stains are particularly bad or when you’re looking for a dramatic result.
