In fact, having a beautiful smile due to charming white teeth is something that all of us want. But before one goes through a tooth whitening procedure or purchases a home teeth bleaching kit, it would be wise to first understand how teeth whitening actually works.

Facts Regarding Teeth Whitening

Below are some key facts you need to understand before you go for any teeth whitening product or procedure. The first layer of the tooth (the outermost) is the enamel. The enamel is basically a thin layer that covers the teeth and forms a wrap for the crown/ The next layer underneath the enamel is the dentin. This second layer is just like the enamel except that it is not as tough and not usually white in appearance.

It is important to know that the teeth's enamel is actually very mineralized. It is made up of strands which are rod-like crystalline substances. The density of these rod-like strands differs from person to person although they are commonly tightly packed. The density of the tooth's enamel has a lot to do why one person has tougher teeth than another person's. Generally, though, all of us get white shiny teeth and the more serious levels of discoloration appear later in life. Understanding these points can help you have a clearer picture of how teeth whitening works.

Are Teeth Whitening Essential?

Going back to the gaps in the enamel of the teeth, understand that these gaps in fact fill up with tannins and debris over time. One basic fact is that anything you put in your mouth contributes to the level of staining and discoloration your teeth will get. With this stain layer getting thicker over time, a person gets greater levels of teeth discoloration over the years. Thereby, teeth whitening become a basic necessity even with consistent adequate brushing and flossing, particularly if you want whiter and cleaner-looking teeth.

What is in Teeth Whitening Products?

The good news is that while various staining agents work their way through the enamel's rods, whitening agents from teeth whitening products also do. Examples of the popular teeth whitening agents are hydrogen peroxide (mainly used in in-clinic treatments) and carbamide peroxide (milder whitening agent mostly found in home teeth bleaching products).

Keep in mind that it is not only the enamel that stains. The dentin layer of the teeth is also reached by staining agents. A person who has highly stained teeth can have much use for more intensive teeth whitening procedures and products.
