Teeth Whitening: What It Is And What Types Exist


More and more the population is concerned with dental aesthetics: we all want to have a whiter and more beautiful smile. More often, patients request tooth whitening, which allows the color of the enamel to be lowered from 2 to 4 tones.

There are different whitening techniques in the market with different advantages and disadvantages. Over the years they have evolved to the techniques that are used today (the concentration of the product, the pH and the technique of application are varied).

The passage of time, poor hygiene, tobacco, the consumption of food with dyes, some medications or drinks (such as coffee or red wine) darken the enamel of the teeth and produce spots on them. However, the greatest concern of patients is sensitivity and dental demineralization.

Teeth whitening

What is it?

This technique should be supervised by a dentist to avoid dental sensitivity problems.

The procedure consists of applying a bleaching gel of hydrogen peroxide or carbamide peroxide on the teeth. This produces a chemical change in the enamel and eliminates stains and stains.

Each time new bleaching methods formulated with bicarbonate , activated carbon or other substances that produce a “whitening” by mechanical effect, eliminating the outer layer of the tooth. These methods are less reliable and, in the long term, can cause sensitivity , since they are not supervised.

Tooth whitening, like other dental treatments, can cause side effects such as sensitivity or root resorption , if not used properly. Therefore, it is very important to always do it under the supervision of a dentist .

What types of teeth whitening are there?

Teeth whitening with gel:

Using a photosensitive gel, this technique is supervised by the dentist and obtains effective results.

It is performed by dentists in dental clinics and can be activated or not with LED light. Before beginning the procedure, the dentist makes a revision to verify that the treatment can be carried out without risks.

The teeth are isolated and the gel is applied (with or without light). The dentist is pending throughout the process of the patient’s sensations to avoid sensitivity.

Ambulatory tooth whitening followed by the dentist:

In this case, the gel is prescribed by a dentist for ambulatory use.

As at home the patient is not under supervision, the professional prescribes a bleaching gel with less power to prevent damage to gums or lips. The dentist makes personalized splints to each patient and explains the procedure. It consists in applying a gel on the dental surface and placing the splint during a specific time.

Teeth whitening with commercial products:

Commercial products have a higher risk of irritation and tooth sensitivity in the absence of supervision.

This series of products can be considered as a good option for many people. However, the supervision of a professional is essential. The indiscriminate use of these products can cause hypersensitivity, irritation of the nerves or gums. If they are not used responsibly, they can cause more harm than good.

In summary

If you have any questions, consult your trusted dental health professional.

Teeth whitening is a procedure that can make you have a prettier smile, but that is not free of side effects. Therefore, it must be done under the supervision of a professional. Within the variety of treatments, the most suitable for each patient will be chosen.

Whitening with household products will never achieve the same effect as that performed in the dental clinic. We can never forget that the mouth and teeth are one more organ of our body, so we must take care of our dental health .
