Important Information About High Strength
44% and 35% Carbamide Peroxide Whitening Gels:

The 44% Carbamide Peroxide strength whitening gel is considered the highest concentration available and has the potential to irritate gum tissue during treatments. Higher strength formulas like 44% and 35% whitening gel can whiten teeth slightly faster and with fewer treatments than lesser strength whitening gels, such as 22%. The user may experience increased tooth sensitivity and gum irritation, common side effects of peroxide based teeth whitening. If gums become irritated during treatment, that usually indicates that too much whitening gel has been applied to the dental impression tray.

It is important to note that when dental impression trays are formed well, only a very light strip of whitening gel is required to fill the space between dental tray walls and teeth. Excess gel applied will remain suspended on gum tissue, which can cause irritation. It's recommended to apply small dots of gel into dental tray and then spread the gel evenly along the tray impression using syringe nozzle. It may appear to be not enough gel applied, but when activated the gel expands and will provide adequate tooth coverage.

For all whitening gel, it is advised on instructions cards supplied; "Should tooth sensitivity persist, reduce treatment frequency and/or duration. If continued discomfort is apparent, discontinue use and consult your dentist." All whitening gels are intended for use by individuals with healthy teeth and gums. Gel should not be used by anyone with periodontal disease, decayed teeth or open mouth sores.
