Abstract
Tooth bleaching is one of the most conservative and cost-effective dental
treatments to improve or enhance a person’s smile. However, tooth bleaching is
not risk-free and only limited long-term clinical data are available on the side
effects of tooth bleaching. Accordingly, tooth bleaching is best performed under
professional supervision and following a pre-treatment dental examination and
diagnosis. In a craze for getting that flash Hollywood style smile, the majority of
people rush into teeth bleaching without realizing if there are repercussions.
Hydrogen peroxide is an oxidative agent commonly used for dental bleaching
procedures. Hydrogen peroxide acts as a strong oxidizing through the formation of
free radicals. Internal and external bleaching procedures utilizing 3-35% hydrogen
peroxide solutions or hydrogen peroxide releasing agents, such as sodium
perborate or carbamide peroxide can be used for whitening of teeth. Whitening
mouth rinses appeared recently in the market and manufacturers advertised that
they could prevent stains and fight plaque build-up. Generally a low concentration
of hydrogen peroxide (1.5%) can be used in the formulation and it may protect the
teeth surface from new stains. Listerine is one of the most common pre-brush
rinses in market. Although generally positive results have been reported
concerning its whitening ability, concerns still remain as its effect on dental
tissues.
