Are there any negative effects on my teeth from using whitening products?
Extensive research by the Eastman Institute for Oral Health has proven that orange juice and other acidic fruit juices cause more damage to your teeth by decreasing hardness and increasing roughness of tooth enamel. The effects of 6% hydrogen peroxide, the common ingredient in professional and over-the-counter whitening products, are insignificant compared to acidic drinks. The orange juice decreased enamel hardness by 84%, no significant change in hardness or surface enamel was found from whitening.
Weakened and eroded enamel may speed up the wear of the tooth and increase the risk for tooth decay to quickly develop and spread. Most soft drinks, including sodas and fruit juices, are acidic in nature.
