Abstract
One of the most important complications of orthodontic treatment with fixed appliances is the development of white spot lesions (WSL) which represent the first clinical observation of dental caries. Fluoride is an efficient prophylaxis for WSL; however, its excessive use may lead to fluorosis. In addition, other chemicals (e.g., chlorhexidine) that have bactericidal effects may negatively affect the oral microflora. In the last decade, interest has shifted to using natural products that have beneficial effects on health. Using dental products (toothpaste, mouthwash, or oral gel) containing herbal extracts, has been shown to inhibit pathogenesis of cariogenic bacteria and consequently reduces enamel demineralization. Future longitudinal and in vivo studies are needed to explore the advantages and disadvantages of dental products containing herbs.
