How Temperature and Handling Methods Affect Whitening Gels (2024)

FAQs

Why does whitening gel need to be 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 heat from the laser speeds up the whitening process, both whitening and dehydrating the enamel, giving quicker results. However once the enamel rehydrates, the teeth appear to darken again and further “top ups” are often required.

Anywhere in your home where heat isn't trapped in a confined space can be a great place to store tooth whitening kits when not in use. For some, under the bathroom cabinet or in a linen closet is appropriate. Others who live in extremely warm climates may want to store tooth whitening kits in the refrigerator.

After you have closed your teeth whitening gel product you can put it in the fridge to prolong its shelf life for up to 2 years. If you decide to store it un-refrigerated it will last for about 1 year. It is very important that you keep it in the fridge and do not attempt to freeze it.

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.

Store trays in the tray holder and gel in cool dry place away from heat and direct sunlight. The gel may be refrigerated to prolong the shelf life, but do not freeze. You may expect some slight gum sensitivity from wearing the trays, and your teeth may feel very slightly sensitive.

The stability of hydrogen peroxide solutions is influenced primarily by the temperature, the pH value, and above all by the presence of impurities with a decomposing effect. An increase in the temperature promotes the decomposition as well as a higher pH value.

The teeth at this temperature were more brittle. The surface showed multiple irregular cracks. At 600°C, the surface became irregular, with hard tissue flaking off. Enamel separated from dentin.

laser teeth whitening is the safest, quickest, and most effective option among the types of teeth-whitening treatments available. However, there are ultimately several ways to whiten teeth, and the most suitable option will depend on your timeline, budget, and priorities, as well as the nature of the discoloration.

During shipping, refrigeration is not required. Once received, some Opalescence™ teeth whitening products require refrigeration, and others do not. Keep Opalescence Go™ teeth whitening trays and Opalescence™ PF 35% and 45% syringes stored in a refrigerated environment between 36°F (2°C) and 46°F (8°C).

Do you spit out teeth whitening gel? ›

As the gel comes into contact with saliva, it should start to foam. If any of the solution seeps out of the tray, a cloth can be used to wipe it off to prevent gum irritation. It is important to not swallow any of the bleach and spit into a sink if necessary.

Gum irritation: soft tissue irritation or chemical burns can happen during the whitening process if bleach is left on your gums for too long. This can be painful, cause white or red patches on your gums and take a while to clear up.

If you've left your teeth whitening gel on for too long and are worried that it might have caused damage to your teeth, try not to fret. You may notice some slight sensitivity of the teeth, white spots on the gum or white flecks on teeth, or numbness on the gumline.

Most teeth whitening agents are good for approximately a year after it they have been manufactured.

Remember to comply with TSA's liquid restrictions if your teeth whitening kit includes gels or liquids. Pack these components in clear, leak-proof containers and place them in a quart-sized, transparent plastic bag. This preparation aligns with airport security requirements, facilitating a smoother screening process.

Generally, teeth whitening gels containing peroxide, such as hydrogen peroxide or carbamide peroxide, require refrigeration. These ingredients are responsible for the whitening effect by breaking down stains on your teeth.

These products are typically marked down when they're close toexpiring. Using expired whitening products means you won't get the results youwant. When they expire, the hydrogen peroxide in them breaks down and leavesonly water and oxygen, which won't brighten your teeth.

Each packet comes with and upper and lower pre-filled bleaching tray. Product must be kept refrigerated. Before using, allow product to warm to room temperature, this will make it easier for the tray to adhere to the teeth.
