Connection between Teeth Whitening and Weakening Of Tooth Enamel

One of the best features of your personality would be your white and bright smile. For this purpose, you may opt for teeth whitening every now and then. However, you may wonder if teeth whitening can be dangerous for your smile in the long run.

What is tooth enamel?

It would be worth mentioning here what tooth enamel is. Tooth enamel is the outer layer of teeth. Although this layer is quite strong, it can get worn down due to exposure of acids which come from foods and beverages we consume on daily basis. The damage to enamel leads to the exposure of dentin which is a layer under the enamel. Since enamel is a white translucent material, dentin is the layer which gives tooth its color.

Way teeth whitening works

There are two ways you can whiten your teeth. You can either use bleaching or non-bleaching whitening products. However, you need to be sure that the whitening technique you are going for is capable of delivering the result you need.

Bleaching products are usually loaded with carbamide peroxide or hydrogen peroxide. Both of these ingredients can whiten the teeth pretty quickly. Bleaches are more commonly used in the dental offices. Moreover, the whitening strips, gels and trays also use bleaching agents for whitening the teeth.

Another type of whitening products uses non-bleaching agents. Non-bleaching products include whitening toothpaste, soda, and activated charcoal. In order to lift the surface stains, these products use abrasion instead of chemicals which are usually present in bleaching products.

Side effect of whitening

Now, let’s talk about a common perception that consistent teeth whitening procedures can ruin your smile. It’s not true. Yes it’s the fact that you may feel sensitivity right after the whitening procedure but this sensitivity doesn’t remain there for very long time. Tooth enamel contracts and expands during the whitening procedure, and it may lose some minerals too. But enamel is healed due to presence of saliva in the mouth. Nevertheless, you have to keep in mind that your teeth will become more sensitive to staining after the whitening procedure. So, you have to make sure that you are not consuming any kind of teeth staining foods and beverages. Furthermore, it is quite necessary to work on quitting the habit of smoking if you have this habit.

You have to make sure that you are not having any medications which can make your oral cavity run out of saliva, unless you are in the dire need of those medications. Visit your dentist to discuss about your prescription medication which can give mouth dryness as a side effect.
