The term “bleaching” can only be used in the United States if the teeth can be whitened beyond their natural color. The teeth have a particular level of whiteness that occurs naturally in healthy teeth, and the only way to get teeth that are whiter is to use chemicals or other commercial methods.
Bleaching refers to using a chemical such as hydrogen peroxide or carbamine peroxide to whiten the teeth. Most types of tooth whitening use some form of peroxide for whitening, but the concentration must be very high in order to be considered bleaching, because only very high concentrations can whiten teeth beyond their natural shade.
Hydrogen peroxide works much faster than carbamide, and concentrations are usually 9% to 40%. This is usually done only in dentist’s offices, because of the danger of using such high concentrations.
Home kits usually use carbamide. It works slower, with concentrations around 15%. A 15% concentration of hydrogen peroxide is equivalent to a 5% concentration of hydrogen peroxide. While carbamide peroxide is slower, it is also much safer to use. This is why it is usually used in home whitening kits instead of hydrogen peroxide.
Can you whiten teeth with regular hydrogen peroxide?
A lot of people want to know if they can just purchase hydrogen peroxide in the store and use it to whiten their teeth. Yes, it is possible to do this. You can whiten teeth slightly using regular hydrogen peroxide. But you must consider the fact that the peroxide you can buy in a bottle is a very low concentration, thus it won’t be as effective as products made specifically for the purpose.
Also, you will have to keep the peroxide in your mouth for quite a while in order for it to be effective. This could become very frustrating, and may also irritate your gums, tongue, and other parts of your mouth.
It’s a better idea to buy products that are specifically designed to whiten teeth. This is safer, and will generally be much more effective and will work much faster.
