Understand Teeth Whitening Bleaching

Once this is clear, we could dive into the common risks of these whitening techniques, how to whiten your teeth naturally as well as illustrating the most advanced strategies to have a healthily whiter smile.

These techniques are going to be discussed one by one all in Depth in separate articles …

… First, let’s dive into understanding some definitions …

The 3 Types of Stains:

Teeth Stains 2Teeth Stains 1

A stain is a discoloration that can be clearly distinguished. They are caused mostly by some chemicals or physical interaction of two dissimilar materials.

There are 3 main categories of stains that cause our teeth discoloration.


Extrinsic stains appear on the surface enamel layer of tissue on our teeth.

You can refer to ‘If you wish having White Teeth … Avoid SMOKING! to know more about this kind of staining.

Intrinsic Stains:

When the dentin (the deeper layer of tissue) becomes discolored we start talking about Intrinsic Stains.

This happens when there is too much exposure to fluorosis (especially while teeth are forming) or to Antibiotic (especially in the early life of a person).

A tooth Trauma caused by a bad injury can also permanently discolor the teeth.


Yea, yea … When you get older your teeth gets older too … 🙁

…Anyways …

There are 2 main reasons for this:

  • The accumulated stains through the years tend to appear and discolor our teeth.
  • The enamel becomes thinner and thinner which makes it easier for stains to establish.

It is normal after several decades drinking coffee and brushing unconsciously to notice teeth yellow with age.

Most people are confused when it comes to the the difference between ‘whitening’ and ‘bleaching’?

Whitening vs Bleaching

Even if both terms seem to be used for turning our teeth from yellow to white, still most cultures lean toward using the “whitening” term.

I think that Marketing played a huge role in that as the term “Bleaching” showed less efficiency in Promoting teeth whitening products.

Again, there is difference between the 2 terms …

… Bleaching means all possible strategies and techniques that address intrinsic stains …

… Whitening refersall to strategies and techniques that address extrinsic stains.

In addition to the most often used Chemical Strategies there is also some interesting Mechanical Strategies you need to know about…

A big majority of people still think that there are only chemical Strategies to Whiten/Bleach our Teeth, nevertheless, there is also some Mechanical Strategies that could do very well.

Chemical Strategies:

Chemical whitening strategies

Chemical methods are about addressing both extrinsic and intrinsic stains using various bleaching agents.

Most of commercial whitening Products use chemical bleaching ingredients to achieve their whitening goals …

… an at home kit, a professional whitening treatment at your dentist’s office or just a commercial ‘whitening’ toothpaste, most of those techniques use chemical means for whitening purposes.

By penetrating the teeth and bleaching the dentinal layer of tissue as well, these agents give an edge to bleach extrinsic and intrinsic stains all at the same time.

Mechanical Strategies:

Mechanical Whitening Strategies

Most choices for Mechanical Strategies are ingredients such as clay powders, hydrated silica and baking soda …

… This helps to remove surface extrinsic stains from your teeth.
