According to a recent study, held by the researchers at the UCL Eastman Dental Institute, poor cleaning may allow for build-up of microbes on orthodontic retainers.
The study was published in the "Society for Applied Microbiology's," journal Letters in Applied Microbiology. Dr Jonathan Pratten, together with his team studied the types of microbes which live on retainers. The study showed that potentially pathogenic microbes were growing on at least 50 percent of the retainers. This may very well indicate a need for the development of improved cleaning products for orthodontic retainers.
