Some products are just plain better than others, so I've rated them all. I'll review a few of them here.
The best tooth whitening products on the market are the ones that have a strong chemical in them. These whitening products contain high concentrations of vitamin C and B complex. Many other brands on this page are vitamin-only products, but I'm going to give them the benefit of the doubt. For some teeth, vitamin C has a calming effect that can make the rest of the teeth easier to clean. Some people don't need vitamin C. For some, it can be harmful. In general, the best teeth whitening products contain at least 30 percent of their vitamin C or more. I recommend you find a vitamin-containing tooth whitener that has about 20 to 40 percent vitamin C. Many of these brands have a very high concentration of vitamin C because they are vitamin-based. They also use the most effective ingredient.
The most common product to use to whiten your teeth is an oil-based product called sodium salicylate. It can be used alone or with other products. You may find salicylate is available in different strengths and in different colors. To determine if you're using a salicylate tooth whitener or other products, I recommend reviewing the ingredient list for the product you're buying.
