Frequently Asked Questions
You asked, we answered! We’ve put together some of the most commonly asked questions about our ultraLED™ teeth whitening. If you can't find the answers you're looking for below, head over to the Smileflex Help Centre for even more information.Yes! The mouth tray is flexible and will fit all mouth sizes.
Yes but keep in mind, artificial dental work will not whiten. They are colour matched at the time they are created and do not have pores. The colour of your dental work cannot be changed (unless it is replaced).
All teeth whitening work by absorbing into pores on the tooth surface. The active whitening agent in our dental grade formula is Hydrogen Peroxide (H2O2), a naturally occurring compound which breaks down readily into water (H2O) and a single oxygen molecule (O). This single oxygen molecule is a strong oxidising and disinfecting agent, and is what gives Hydrogen Peroxide such effective whitening properties.
Teeth whitening is only achieved with either Hydrogen Peroxide (HP) or Carbamide Peroxide (CP). HP and CP produce the same results, however HP whitens 3x faster and requires 3x less strength to that of CP to achieve the same results. This is because of the time needed for the CP to break down into HP first.
While formulas such as PAP and PAP+, are merely a temporary teeth "lightening" effect by dehydrating teeth rather than whitening and removing tooth stains. In the dental industry we call this "rebound" and people using those products find once their dehydrated teeth return to health 3–4 weeks later, their original tooth stains reappear (as they were never removed).
With all factors considered, it's why Smileflex chooses Hydrogen Peroxide as its active whitening agent to achieve the best and longest lasting professional results.
Yes! Our product has proven to be highly effective at removing stains from teeth including coffee, tea, wine, tobacco, tetracycline, and various other tooth stains.
