But when it comes down to it, all you need to know is that they both whiten your teeth, just in different ways. Hydrogen peroxide is more commonly used for day whitening, while carbamide peroxide is used for night whitening. And you can choose which you would prefer when ordering your teeth whitening kits.

The good news is, one doesn't work better than the other. A journal published by American Dental Association showed that while carbamide peroxide shows slightly more dramatic results at first, products containing both ingredients produce exactly the same results.

Like many chemicals, hydrogen peroxide is only safe in small doses. While hydrogen peroxide is generally recognized as safe for whitening, the key lies in using it in appropriate concentrations. Anything stronger than a 3% concentration is dangerous, and many whitening products dilute the solution even further.

Hydrogen and carbamide peroxides are secure options for bleaching vital teeth, maintaining the substrates healthy. It is very important that dentists possess the necessary knowledge of these substrates and also the management of the peroxides.

The concentration of hydrogen peroxide in store-bought teeth whitening kits can be as high as 10%. Dentists may also offer whitening treatments with hydrogen peroxide concentrations of up to 40%. On the other hand, most store-bought hydrogen peroxide has a 3% concentration.

Tooth whitening is most often done using peroxide-based bleaching agents. At-home systems contain from 3% to 20% peroxide (carbamide or hydrogen peroxides). In-office systems contain from 15% to 43% peroxide. Generally, the stronger the solution and the longer you keep it on your teeth, the whiter your teeth become.

This suggests that low-concentration treatments of hydrogen peroxide, applied for shorter periods, have the least potential to damage your teeth. According to a 2004 study, scientists found that a 5 percent hydrogen peroxide solution was just as effective as a 25 percent solution at whitening teeth.

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.

There's no definitive answer to this question as it largely depends on individual factors. However, most dentists use a shade guide to determine the level of whiteness that can be achieved. This guide has 16 shades, with the whitest shade not being pure white, but rather a light shade of grey.
