Anna K. presents to the dental office with slight generalized periodontitis.  She brushes her teeth 3x day with a soft manual toothbrush and tries to floss daily, but states that flossing is difficult due to her arthritis.  She is highly motivated and would like to implement some new oral home care suggestions. Based on the information above, which interproximal aid would you recommend for Anna?
