Oap Cleaner was started by a team of dental hygienists in a top 100 Invisalign provider office in New York City. Due to the lack of acceptable options with which their patients could clean their expensive appliances, they formulated a comprehensive yet gentle cleaner that would have dental and orthodontic appliances LOOKING and FEELING brand new. Thus OAP Cleaner was born! No more ineffectual tablets with lengthy soaks or peroxide based cleaners that ruin expensive dental appliances.
