How Temperature and Handling Methods Affect Whitening Gels? ›

If left at room temperature or exposed to warmer climates and hot shipping temperatures, the peroxide gel will lose potency. Most whitening gel manufacturers will store their gels in warehouses, which are usually not air-conditioned, let alone refrigerated.

Those hydrogen ions are acid (pH = potential of Hydrogen). Whitening gels therefore become more and more acidic as they break down, resulting in an ever increasing possibility of sensitivity and pain. Constant refrigeration virtually stops breakdown of whitening gels.

The challenge with such instability, however, is that all whitening gels will begin degenerating immediately upon manufacture unless they are kept under constant refrigeration. If left at room temperature or exposed to warmer climates and hot shipping temperatures, the peroxide gel will lose potency.

NON-refrigeration of whitening products therefore results in degradation of whitening gels as well as an acidic pH by the time they are used on patients.

When it comes to in office teeth whitening patients prefer the use carbamide gel without the additional use of UV light treatments. The use of bleach trays to apply a carbamide peroxide solution is as effective as the same whitening tray use with UV lights.

With increase in temperature, the teeth progressively became fragile and difficult to handle. At the temperature of 600°C, teeth from all the three groups were disintegrated completely as soon as they were put in 10% formal formic acid for decalcification.

Also, if you have poor oral health or an underlying medical condition that affects the teeth, the teeth whitening procedure may make the teeth yellow. This is because the dentin has a yellowish hue under the enamel. So, when the enamel thins, your teeth become translucent and may look yellow.

Opalescence™ PF 10%, 15%, and 20% syringes should be stored between 36°F (2°C) and 81°F (27°C), which means that these products may be stored refrigerated or at room temperature.

Place a small amount of teeth whitening gel into the tray(s). 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.
