TEETH WHITENING
The color of the teeth is personal, a bit 'like the color of skin, each has its own, and it is never pure white as the white porcelain. The "white natural teeth incorporates subtle nuances in tones of yellow and gray, sometimes the brown or reddish, more or less pronounced, increasing in intensity from the edge of the free gingival collar of each tooth. The canines, among others, have usually a deeper color than others. Contrary to what you may think it is that determines the color of the enamel of the teeth. In fact, it does not have its own color, is translucent, from his surface reflected the color of the underlying dentin. Over time, however, may stain the enamel pigments absorb from food and beverages, while the dentin tends to thicken for affixing this continues into the inner chamber in the crown of the teeth. This means that with the aging teeth darken and lose their original brilliance.
The current progress of cosmetic dentistry help restore the tooth color to white and the brightness of a time you can even get to get a white a little 'unnatural', such as porcelain, devoid of shades of color. In reality, everyone can choose the intensity of discoloration da raggiungere perché la capacità di sbiancamento dei prodotti professionali dipende dalla concentrazione del principio attivo e dal tempo di permanenza a contatto dei denti, così come si può scegliere il tempo di esposizione alle radiazioni solari per raggiungere la desiderata tonalità di abbronzatura. Alcune persone richiedono proprio il colore “bianco porcellana” perché desiderano far apparire i loro denti più bianchi possibile.
Tecniche professionali e metodi "fai da te".
Esistono tecniche professionali di sbiancamento dei denti e metodi “ fai da te ”.Tra i vantaggi delle prime ci sono:
- Garanzia di raggiungere il più elevato sbiancamento possibile
- Un minimo impegno di tempo e pazienza per un massimo risultato
- Assoluta salvaguardia da spiacevoli effetti indesiderati come eccessiva sensibilità termica e irritazione gengivale.
L'apparente vantaggio dei secondi è nel costo, ovviamente più basso rispetto alle più efficaci tecniche professionali. Infatti i potenti prodotti utilizzati in un ciclo di trattamento sbiancante professionale richiedono per il loro utilizzo conoscenze ed esperienza e hanno un costo di base molto più alto rispetto ai prodotti fai da te reperibili nelle farmacie e nei grandi magazzini.
L'efficacia più bassa di questi ultimi fa sì che dopo ripetute applicazioni, ritenute di solito un po' inconvenient by users, can produce limited effects and that the return to its previous state be soon.
