What is Led whitening?
As we told you, LED whitening in clinic is the most effective, the healthiest and the most durable.
After the revision and dental hygiene, the dentist introduces you in the mouth an appliqué that allows you to keep it open without discomfort and without you having to think about it. In turn, it will show you the current color of your teeth using a dental chromatic meter.
Next, use a gel on the upper part of the gums to protect them and, finally, gently spread the whitening product over the enamel, tooth by tooth and with special care so that the result is excellent.
Once the preparation is finished, a special Led light is directly focused on the denture between 30 and 45 minutes. At the same time, you put special glasses that prevent you from suffering discomfort because of the led.
The Led light reacts to the whitening product, which produces free radicals that penetrate the enamel and eliminate the chromospheres, the molecule responsible for the pigmentation of the teeth and responsible for its yellowish tone.
After the estimated time, the dentist will remove the protective gel from the gum, will ask you to clarify and re-measure the tone in the dental chromatic meter so you can see, in situ, the number of tones lowered.
Effectively, the result is immediate.
