Is it safe?

Yes. The WIT® professional teeth whitening procedure will not soften enamel or existing fillings. The primary ingredient in the whitening gel is hydrogen peroxide, which has been safely used in teeth whitening for over 100 years and is recognized as an effective whitening ingredient by the dental community. The percentage of hydrogen peroxide used in WIT® proprietary gel is only 15%, much lower than other whitening gels that often contain 35%-50% hydrogen peroxide.

Safety studies about teeth whitening with BriteSmile

Independent safety studies, conducted by the University of Medicine and Dentistry of New Jersey and confirmed by senior researchers at NYU, prove that the BriteSmile Professional Teeth Whitening Treatment is safe, while clinical studies performed by BriteSmile and others show that our teethwhitening results confirm an average of 9 or more shades lighter and even higher for individuals with darker teeth. Review the highlights from the studies below.

A pre-clinical study on the effect of BriteSmile upon hardness of enamel and composite was conducted by the University of Medicine and Dentistry of New Jersey. The Study concluded: "The results of this study indicate that the BriteSmile Tooth Whitening system will not cause softening of enamel and composite materials tested".

The findings of the pre-clinical study were confirmed by a Scanning Electron Microscopic (SEM), study. The study's conclusions stated that: "The data indicates that the BriteSmile Whitening System did not cause structural or morphological changes of enamel, and it is therefore concluded that the procedures involved are not caustic or corrosive".

Senior researchers at New York University reviewed the data from the SEM and pre-clinical hardness studies. The review confirmed the findings of the University of Medicine and Dentistry of New Jersey researchers. Finding no change in surface morphology and hardness of the BriteSmile treated specimens when compared with untreated controls. The study concluded that: "The results indicate that BriteSmile treatment is safe towards enamel and is not corrosive or caustic".

A clinical study was conducted by BriteSmile and investigators associated with the University of Medicine and Dentistry of New Jersey to evaluate the clinical safety and efficacy of the BriteSmile system. Fifty healthy subjects were selected to participate in the multi-center study. The clinical study found that all subjects had a significant improvement in tooth color, with an average shade change of 8.1 tabs. Additionally, clinical examinations showed all soft and hard tissues were within normal limits.

A study by the prestigious Forsyth Institute also confirmed the 9+ shades average improvement achieved using the BriteSmile process. Additionally, this study confirmed that BriteSmile is completely safe for young adults 14+, paving the way for BriteSmile to become the method of choice for removing stains associated with orthodontic treatment.
