Teeth whitening – how this procedure is performed

There are several ways to return the white color to the teeth, including the use of toothpastes for teeth whitening and other products that eliminate superficial stains for a low cost, as well as eating strawberries that according to herbalists help to whiten teeth or brush with baking soda, but that is not recommended because it wears out the enamel.

In the dental office other whitening techniques are used, not so cheap, that make the teeth look white; the most common is whitening by photo activation.

However, the only way to remove stains and whiten the front teeth that are most noticeable when smiling, is placing the known and expensive porcelain veneers, or apply a micro abrasion technique prior to tooth whitening.

Currently dental aesthetics plays a very important role compared to previous years, and is that many people are choosing to improve their smile because it will always serve as a cover letter.

Dental whitening process

Before starting the tooth whitening process by photo activation, the patient must be evaluated by the dentist since he will determine if this technique is convenient or not, which, incidentally, should not be done while there is caries, periodontal disease or plaque.

The tooth bleaching by photo activation is based on the use of a bleaching gel as carbide peroxide or hydrogen. This is placed through a splint adapted to the dental arch and activated through the application of the light source (LED, laser or ultraviolet).

Before this happens, a gum protector is placed to avoid direct contact between the bleaching gel and the soft tissue (gums, tongue and palate).

The whitening substance is applied on the external face of the teeth and on it the cold light source is turned on for approximately 45 to 60 minutes, achieving a reduction of between 4 and 10 tones. The laser is much more effective, but it causes greater dental hypersensitivity than the LED light and its effects disappear with time, so it is more convenient to opt for the second option.

In certain cases, to obtain better results, a single session is not enough, since some patients may need other sessions to change the natural color of the tooth. The color of the tooth that is wanted must be evaluated and endorsed by the doctor, since it is he who knows what is most convenient for each patient.

Although tooth whitening is a simple and painless procedure, it causes tooth sensitivity during the following days. To reduce pain use toothpastes for sensitive teeth, chew gum to forget the pain and avoid whitening for a while to give rest to the teeth.

During the days after tooth whitening the person cannot drink coffee, tea, red juices, soft drinks or have dyes because the teeth more easily capture the pigments contained in drinks and foods that stain and spoil the teeth.

For better aesthetic results, whitening performed by the professional must be accompanied by the splint made by the dentist, adapted to the patient’s mouth, for whitening at home. This is used several hours a day or during the night for two weeks, although on average it is sufficient to use them for 30 minutes a day for five or six days.

It is important to follow the instructions dictated by the manufacturer and the dentist since the time of action will depend to a large extent on the material used. Teeth whitening should be done once a year to prevent tooth wear.
