Don’t dismiss the often lower pricing associated with home teeth whitening kits and teeth whitening gels that you can purchase online, some of the products online are actually made in the USA by some of the same companies that make the extremely expensive kits you find at dental offices. Do your homework though, there are a lot of false claims out there as well as a lot of import products that are either not regulated by the FDA, untested and unproven or simply poor quality, which can lead to health issues.
