Consumer Experience

Without the proper amount of fluoride, your teeth will begin to weaken over time. The enamel will become thinner and will no longer be able to remineralize quickly enough to replace the amount of demineralization occurring. This will make it easier for bacteria to creep in and take over.

After testing 21 different teeth whiteners, SmileDirectClub's whitening kit was an easy pick as our best overall - our teeth visibly whitened in just a week without causing or exacerbating any sensitivity.

Dental veneers are a great way to permanently whiten your teeth, so no more white strips and no need for whitening treatments. A dental veneer is a thin piece of porcelain material that is placed on top of natural teeth. They are bonded to the tooth with a cement-like material to ensure a stronghold.

You should still refrain from using such products more often than 3-4 a week, so as to prevent gradual enamel erosion. Tooth whitening works by bleaching your teeth with one of two ingredients: carbamide peroxide or hydrogen peroxide. These substances are slightly different, but ultimately work in the same way.

Place the whitening tray(s) in your mouth carefully, making sure that it is seated all the way. Remove any excess gel from the gum tissue with your finger or dry toothbrush. Keep the tray in your mouth for 30-60 minutes. After 30-60 minutes, remove and clean the trays with cold water.
