When you wipe off the bleach and first look in the mirror, the effect might leave you more satisfied with what you’ve been sold. If you warm teeth, the enamel dries out and turns whiter, says David Sarrett, dean of dentistry at Virginia Commonwealth University. And though there’s no evidence that the available systems do damage to nerves, says Carey, there’s also probably no reason to risk being the first.Īs it stands now, the systems that produce heat do have a short-lived effect that’s separate from the bleach reaction. But too much heat is bad for the soft innards of your teeth-the pulp, which consists of connective tissue and nerves. In theory, dentists could just crank up the temperature to get a reaction that’s noticeably faster. And based on this kind of data, it seems that the light can’t simply reduce the amount of time you spend in the chair to achieve your desired results. If the lights sped up the reaction, you’d expect the group that got the light to have a greater change. Study after study shows that if you put the same concentration of bleach on a patient’s teeth, sit them down for the same period of time, and shine a light on one group and not the other, they will ultimately wind up with the same difference in tooth color. But Clifton Carey, a chemist at the University of Colorado who studies the mechanisms behind dentistry, says that in practice, there is simply no evidence that the light systems installed in so many dental practices across the country produce enough heat to make a difference in the speed of the reaction that is whatsoever noticeable or measurable. Lights that produce heat. These are prevalent in dentists’ offices. Lights are an add-on to the chemical stain removal process that supposedly either heat up the bleach or react with a photocatalyst in the gel to speed the chemical reaction.

The do-it-at-home versions on Instagram tend to be on the inexpensive side and consist of basic bleach trays and LED lights, but there are kits on the market that go for upwards of $200, and are endorsed by practicing dentists. Or you can take them off chemically with bleach deployed in trays, paint-on gels, or strips, and sometimes in toothpastes. You can physically scrape stains off of them, which is how many whitening toothpastes works. As one dentist who declined my interview request about the merits of lights said, “In my opinion, they’re BS.” How teeth whiteners workĭespite the variety of kits and systems to choose from, there are two basic ways to whiten your teeth.

Nor can they shorten the amount of time you have to spend with a mouth full of whitening chemicals to achieve your desired tooth shade.

Though some lights can add a temporary boost that fades within a day or so, none ultimately make your teeth whiter than trays of bleach or whitening strips alone.

After a week of reading some two dozen papers, interviewing three dentists, and trying one of the variety of kits that are out there myself, I’ve found there’s no evidence that lights will improve the appearance of your teeth in a lasting way-even those deployed by a professional or designed by a dentist. If you’re thinking of buying a teeth whitening kit that comes with a blue light because you saw Khloe Kardashian or other celebs hawking one on Instagram-or heard their merits sung on beauty blogs-don’t.
