There are bleaching systems and cosmetic restorative procedures that can offer the oportunity for whiter smiles to everyone. Teeth whitening procedures have been performed for over one hundred years. As far back as 1877, procedures involving the use of oxalic acid to whiten teeth were reported. Hydrogen peroxide was introduced as a tooth bleaching agent back in 1884 and in 1918, the use of high-intensity lights in conjunction with the hydrogen peroxide was used to speed up the bleaching process, according to a report by the ADA . Minor side effects from the procedures may include transient mild tooth sensitivity to temperature changes and mucosal irritation.
Most side effects associated with the teeth whitening procedures disappear within one to seven days.
Many patients have slight discolorations on their teeth due either to aging, discolorations from the natural build-up of organic pigments over time, trauma to the teeth, coffee, tea, smoking, or extended use of medications during the development of the teeth. There are a variety of procedures available today that allow just about anyone who wishes to brighten their smile, the opportunity to do so. Many people will lighten their teeth because it helps their self-esteem and gives people a little extra confidence and improve your first impression. Patients who have sensitive teeth should consider using the milder solutions for bleaching, since the in-office techniques may cause additional sensititvity. In addition, patients who have very thin teeth may find that the bleaching techniques, while they may lighten the teeth, may show more of a grey translucency after the bleaching.
