This method involves use of a fitted tray containing carbamide peroxide-bleaching gel worn for 2 to 4 hours a day or overnight. Usually by following the manufacturer instructions tooth whitening is noticeable in a few days, lightening the teeth by 1 or 2 shades.

With these types of cases (when utilizing a 10% carbamide peroxide bleaching gel, with once-daily sessions lasting at least 1 hour), studies have shown (Strassler 2006): The first 2 weeks of treatment will usually produce about 90% of the total whitening effect that you ultimately achieve.

Patients who want to whiten overnight can use White Dental Beauty 10% carbamide peroxide. Recommended wear time is two to four hours or overnight.

We recommend that you whiten your teeth with 10% carbamide peroxide, or 3.6% hydrogen peroxide. It is gentler on your teeth to use slightly less strong tooth whitening, but with more applications to achieve the same level of whiteness as you would do when using stronger whitening gels.

The 44% carbamide peroxide whitening gel is a maximum strength concentration. It has greater potential for tooth sensitivity and/or gum irritation. This can be avoided or minimized by applying only a very thin strip of gel to tray.

Hydrogen peroxide 3%

It works in the same way as carbamide peroxide. It foams and bubbles, which loosens and softens the wax. To use hydrogen peroxide 3%, fill the affected ear(s) and leave in place for 15 to 30 minutes.

Conclusion: Carbamide peroxide in 16% and 35% concentration are effective and safe for bleaching discoloured vital teeth, however, 35% concentration gave significantly more lightening effect without additional side effects compared to 16% concentration.

It is the Hydrogen Peroxide that is taken up into the porosities in the enamel rods and then enters the dentinal tubules and lightens teeth. Carbamide peroxide is a third as strong as Hydrogen Peroxide, so a 30% solution is equivalent to a 10% solution of Hydrogen peroxide.

Carbamide peroxide is commonly used in teeth-whitening kits. These kits are sold for home use or used in dental offices.

Finally, the chemical activity of the peroxides kill the dangerous bacteria that cause cavities and gum disease.

Based on SEM observation, bleaching teeth with carbamide peroxide does not increase the susceptibility of enamel to staining and does not alter the topography of the enamel. Using higher bleaching concentrations did not increase tooth whitening as a function of time.

Carbamide peroxide is a medication used to loosen ear wax, whiten teeth, and clean oral wounds. Carbamide peroxide, also known as urea-hydrogen peroxide, is a water-soluble, white crystalline solid compound consisting of hydrogen peroxide and urea.

Today, most dentists use hydrogen and carbamide peroxide gels between 10-40%, which are chemically activated or by different light sources, such as halogen light, laser or plasma arc [9], See (Table ​1).

This activation occurs by peroxide oxidization of cysteines residues in TRAP1 and reaction of oxidizing agent with Fe₂₊ via Fenton reaction ¹⁷ . Therefore, reduced tooth sensitivity can be expected using carbamide peroxide since lower concentration of hydrogen peroxide is available.

16% Carbamide Peroxide (5.7% Hydrogen Peroxide) = use 1 x 90 minutes/day to overnight, while sleeping, if no sensitivity arises. Conduct your whitening session once per day until desired level of whitening is attained.
