Quick teeth whiteners are a popular dental treatment for people who are sensitive to whitening agents.
They can also be used to help whiten a hard tooth.
But some experts say they don’t work very well.
And they say that some products, like this one, can have more side effects than others.
The products that are marketed as whitening products are generally marketed for people with moderate to severe whitening problems, like people who have a history of cavities or a condition called denture wear.
And many have a lot of ingredients that can cause allergic reactions.
But a new study published Monday in the journal PLoS One found that, when it comes to the whitening effects of these products, they may not work as well as they’re advertised.
For the study, researchers looked at more than 8,000 Americans who were using a range of dental products to treat tooth whitening.
The study included more than 7,500 people who were in their 30s and 40s, who had mild or moderate whitening issues, and who were taking two types of whitening supplements.
The results showed that while some whitening remedies did seem to work well, they were not as effective as those marketed as treatment for whitening or tooth whiteness.
The study authors concluded that there may be a need for more research on how to best use whitening therapies to treat whitening-related whitening symptoms.
And some people who took a lot more whitening treatments were found to have more severe whiting problems.
The findings could mean that a whitening product might be a better option for some people than others, said study co-author Jennifer P. Johnson, an associate professor of preventive medicine at the University of Texas Health Science Center at San Antonio.
For some people, the best treatment for tooth whitning may be to use toothpastes and mouthwashes.
For others, a whitener that is effective at reducing whitening can be more effective than a whitened tooth.
The American Dental Association is urging consumers to consider their health when choosing a dentist.
The association also urges consumers to check with their dentist to ensure that a dentist is trained to treat dentition.
