Which dental floss should I use?

Dental hygienists might find themselves on the receiving end of this question on a regular basis.  Oral self care recommendations need to be customized for each client, and many factors need to take into consideration when advising clients about suitable interdental aids.  Factors to consider include: dental anatomy, restorations, embrasure spaces, level of oral health knowledge, manual dexterity, financial resources, and motivation.  For clients that are motivated, have good manual dexterity, and type 1 embrasure spaces, I often answer this question with: "the floss you like the best."  If a client has no contraindications for that type of floss or floss technique, the floss the client prefers is the one that he/she will most-likely use.
