What is tooth whitening and what are its advantages?

Tooth whitening is a treatment used directly on the teeth that can lighten up to 8 shades of enamel colour in general and localised stains. This type of treatment can be performed in a dental office in a total of 1 to 3 sessions. There are also products that can be used at home without medical supervision.

Tooth enamel naturally darkens as you get older, but there are other factors such as coffee or tobacco consumption that increase the likelihood of yellow to grey stains on the teeth. In addition, without good oral hygiene, this problem is greatly exacerbated.

  • Works satisfactorily in 90% of patients
  • Visible change in tooth colour
  • Easy to use
  • Increases self-esteem and confidence
  • Can last up to 5 years
  • Can damage tooth roots
  • Can cause tooth sensitivity
  • Can cause gum irritation
  • Requires several sessions
  • Can be costly

Tooth whitening, without whitening agents or with whitening agents – what should you look out for?

These types of treatments can be found in different presentations and the important thing is that you know which whitening method they use. Below we explain the two variables that you can find in this type of product so that you can take them into account before purchasing yours.

No bleaching agents. There are totally natural products that help in this whitening process. The most common and famous is activated charcoal, which thanks to its elaboration process, the charcoal traps chemical substances in its particles and discards them. These treatments are effective in the long term.

With bleaching agents. Most enamel whitening products on the market contain 10 to 22% whitening agents that intensify the result. These can be carbamide peroxide or hydrogen peroxide and their advantage is that in a short time you can see the results in a radical way.

Without bleaching agents With bleaching agents
Effectiveness Progressive results with constant use Results in 3 to 5 applications
Duration of process From 1 to 2 minutes From 10 to 30 min
Cost Medium High

Buying criteria: factors that allow you to compare and rate different teeth whitening models

To be absolutely sure that the product you buy will meet your needs, and that you will get the results you expect, you need to be aware of purchasing factors that can make the difference between one product and another. Here are some of the factors you should consider.

  • Presentation
  • Quality
  • Grammage per package
  • Ingredients


Presentation is important because it is the method by which you will apply the treatment. Some methods may be more uncomfortable or impractical than others. This does not mean that their efficiency is less efficient, however you should consider the time you have to perform this procedure.

Toothpastes. Toothpastes, commonly called toothpaste, focused on teeth whitening, offer you the convenience of using them as you always do in your oral hygiene routine.

You don’t need to do anything more than brush your teeth with a toothpaste containing whitening agents. You need to use it consistently to see results in the medium term. The degree of whitening is no more than 2 or 3 shades.

Powder. This type of presentation is the most common in organic and 100% natural products. Because of this, the way to apply it is by means of a slightly moistened toothbrush. You should brush your teeth for 2 minutes and then rinse them. The results are gradual although it is more effective than toothpastes.

Band-aids. Band-aids are the first and most effective at-home method to appear on the market. Today they are just as effective and have evolved to provide you with greater comfort and practicality during use. You only have to put them on for 30 minutes a day and after 5 to 10 sessions you will achieve the final result.

Laser. Laser procedures require the use of gels containing bleaching agents. This light activates these agents and must be placed very close to the enamel for it to take effect.

The process of this type of treatment takes about 10 minutes a day. Today it is the most effective at-home method available. The results are almost immediate and you only need a few sessions to get the final result.


The quality of this type of product lies in meeting the standards of health organisations such as the American Dental Association (ADA) or the Mexican Dental Association (ADM).

Some products have a seal of approval from these associations, so if you want to be sure you are using a safe product, look for a seal or inscription that guarantees it is a quality product. These are usually printed prominently on the packaging. If not, check online.

Grammage per package

Each person has different needs based on their oral health. That is why you should consider that depending on the presentation you choose, it should, preferably, be enough for you to finish your treatment.

Toothpastes. Because its use must be continuous in order to get results, it requires a lot of product. The great advantage is that it is the easiest presentation to find.

Powder. This product replaces toothpaste, so its use is also considerable. A 20 g jar lasts for about 3 months, so we recommend that you use no less.

Strips. The use of strips guarantees results from the 3rd application. There are presentations from 7 to 10 treatments (14 or 20 strips). We ask you to consider the number of treatments you need according to your situation.

Laser. As we mentioned before, you need an activating gel that whitens the enamel. This is measured by syringes and each syringe is one application. The number of syringes you need depends on the degree of darkening of your teeth.

The best option is to ask an expert and professional on the subject how many sessions they recommend you to take and on that basis choose your product or, failing that, take advantage of your purchase to acquire a larger number of syringes separately.


Tooth whitening treatments can contain a wide variety of ingredients that can provide advantages in their use. However, there are three specific ingredients that are used for effective teeth whitening.

We recommend that you make sure that the product you choose, if it contains whitening agents, contains at least one of these three ingredients, so you can be sure that it will be an effective product.

Baking soda. It is common in toothpastes because it is an abrasive component that helps to remove surface stains from the enamel.

Hydrogen peroxide. Also known as hydrogen peroxide. It is a chemical compound widely used in whitening products. For dental use it can have a concentration of up to 35% or 40%. Its use must be done with extreme care and always following the instructions to the letter. It is very effective.

Carbamide peroxide. This is made up of one third hydrogen peroxide and urea which is an organic compound. This bleaching agent is used with approx. 16 % concentration in tooth whitening products.
