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. |
