POH Unwaxed Dental Floss is different. It is constructed of nylon and gathered into strands, the multi-filament floss is designed to disrupt and disorganize plaque. The very different, very thin, multiple strands of tiny nylon slip easily between the closest teeth, and is able to get just under the gumline without pushing it further down. POH addresses the individual needs of patients including orthodontic, periodontal and individuals with hard to clean areas such as deep fissures and grooves.
