Professional tooth whitening: how it works

Teeth whitening is a procedure that allows to bring back the whitest dental enamel, especially in those patients who have teeth ranging from a light yellow to a darker color.

Normally, to get a quality service, you should contact your trusted dentist and you should avoid those whitening products, which are sponsored as miraculous but which, in the long run, can further ruin the teeth (for example abrasive toothpastes, whitening pens). , adhesive strips). The correct daily oral hygiene is fundamental, better if with electric brushes more performing than the traditional ones.

Once the appointment with the dentist is obtained, the day of treatment will initially evaluate the color of the teeth and then undergo whitening.

We advise you to include tooth cleaning in the treatment, which is essential to prevent pyorrhea and subsequent dental implant operations, as tooth whitening does not replace this important service, which should be done at least once a year. In fact, these two treatments are often confused.

Tooth cleaning means that hygiene service that involves the removal of tartar, root planing (or scraping of the tartar) and polishing (using a rotating brush).

Professional tooth whitening, on the other hand, involves the use of certain highly concentrated whitening chemical agents (generally gel based on hydrogen peroxide or carbamide), carried by a LED or laser lamp, so that a reaction is initiated that gives shine and shine to the lenses.

But what is the difference between a LED lamp or a laser lamp? Which is better? Let’s find out in the following paragraph.

Dental whitening led or laser?

Professional tooth whitening is always preceded by the application of the whitening gel. Then you can carry out the treatment through certain equipment available to the professional, including:

  1. cold light green led lamps
  2. blue led cold light lamps
  3. laser lamps

The first two LED tooth whitening equipments differ for the duration of the treatment: in the first case it lasts less than the second one.

Laser teeth whitening, unlike the LED one, is able to act more deeply, bringing the peroxide gel to combat discoloration more effectively.

In particular, the diode laser is the most widely used of all, compared to all the others.

Dental bleaching: how much does it cost?

But what is the cost of tooth whitening? Prices usually vary from studio to studio. On average we start from 150 euros/dollars to 500 euros/dollars. Depending on the shade of the teeth, several sessions may be necessary. Remember, however, that bleaching does not last for an unlimited period. In fact, usually, the whitening effect can last from 6 months to 1 year. Finally, if proper oral hygiene is not followed, the main cause of diseases such as periodontitis, and immediately after treatment, smoking and drinking coffee are resumed as before, the effect can last much less.
