Why do you Need Tooth Whitening?

Why Do You Need Teeth Whitening?

Do you know the enemy that causes tooth stains? It is quite interesting to note that every tooth is comprised of an inner dentin layer and a protective outer enamel layer which is much harder.

Regular intake of food stuff, nicotine and caffeine tends to form another coating over the enamel layer like a pellicle film. This film can be removed chemically as well as by scraping by a dentist.

Brushing helps to clean the teeth stains to some extent and there are special abrasive toothpastes which help further the process. Teeth whitening toothpastes are also available which are effective in cleaning such stains on our teeth enamel.

Our teeth enamel is porous in nature. Hydroxyapatite crystals in the form of microscopic hexagonal “rods” make up the enamel.


The accumulation of the foreign substances over the years gets into the pores and settles on the inner layer where it is very difficult to scrape them. Though these deep stains are actually quite harmless, they do not look good.

Thus to get rid of these tough stains, people seek the help of professional teeth whitening procedures.

During such teeth whitening procedures, a bleaching chemical agent is used called carbamide peroxide or hydrogen peroxide.

This is present in a tooth whitener and it triggers a chemical – rather an oxidation reaction – which manage to break the staining compounds.

The chemical compound carbamide peroxide breaks within the mouth into urea and hydrogen peroxide.

The hydrogen peroxide plays a vital role in the teeth whitening process.

Teeth Whitening Products: Pros And Cons

Choosing teeth whitening product amidst the different teeth whitening products available in the market today can be very confusing. And some of the teeth whitening products are not giving your desired result.

If you ask the experts, they will tell you that the best method of teeth whitening is still through your dentist. Not only is it the best, it is also the most effective and the quickest to have whiter teeth.

But then, not all people can afford the fees that come with each treatment. Another thing that hinders them from going to dentists is fear. It seems that as early as childhood, dentists are one of the most feared personalities that people do not want to encounter. This fear continues on in the adult years.

Although dentists do not advise people to choose teeth whitening products, they all agree in saying that these products are effective in some degree. According to studies, teeth whitening products, if used regularly and consistently can result in whiter teeth that can outlast any dentist-assisted procedure.

Another additional plus that teeth whitening products have is that they contain the same ingredients that are being used in professional whitening. Two of the active ingredients needed for whitening teeth are hydrogen peroxide and carbamide. These two are also the ingredients that are present in some of the products that are sold in groceries and drug stores.

The only advantage that teeth whitening products have over professional whitening is that they tend to be very cheap. Everyone who will tumble upon them can simply afford to add them to the list of their basic things.

Most of these products can be bought for $30 or less. Compare this to the $100 or more that you need to pay to the dentist. It will not surprise you why people prefer them over the high fees.

Still, teeth whitening products are found out to have some disadvantages. Some of these are:

1. Suitability.

Teeth whitening products cater to all. But then different people have different needs. What others found effective may not work for others. This is one of the problems that people will encounter with these products.

There are those that have sensitive teeth and gums. The reaction to the products will depend upon the suitability of the products to the persons using them. An option would be to try different products until you find the one that is suitable to you.

2. Strong chemicals used.

You will not know what your reaction to the product until you have tried it out. Since you do not know how sensitive your teeth are, you will also not know what might happen when you start using the product.

Better consult with your dentist first before choosing a certain product.

3. Tray may not fit.

The tray put in your teeth is not exactly fitted after you. So there is a tendency that it may either be too large or too small.

When it is too large, the formula may not work well. On the other hand, if it is too small, it may cause gum bleeding and side effects that will cause bigger problems.

Be sure that the teeth whitening precuts you choose is suited for you. If none of them works, then maybe professional teeth whitening will.
