You may simply improve your smile by whitening your teeth. The best results of whitening your teeth are done with hydrogen peroxide or carbamide peroxide. Hydrogen peroxide is the active whitening agent. It is not the same stuff you get at the store in the brown bottle. That’s 2% hydrogen peroxide and at that percentage will only kill bacteria and not whiten teeth. Also, pay attention to the product before looking at the percentage of the product. One-third of carbamide peroxide breaks down to hydrogen peroxide. So 15% carbamide peroxide will break down or is equivalent to 5% hydrogen peroxide. Carbamide peroxide is used in products that desired to have a longer shelf-life.
Some sensitivity may occur and results vary with the individual. The best method to maintain a healthy white smile is to avoid staining habits such as smoking or drinking dark sugary drinks, dark sauces, coffee, or tea.
