Interdental cleaning removes plaque, the bacterial film found on surfaces a toothbrush cannot reach. This cleaning uses one of two primary tools: traditional string floss (a spool of thread) or a floss pick (a pre-threaded piece of floss mounted on a small plastic handle). Determining which tool best supports a consistent and effective oral hygiene routine requires comparing cleaning ability, ease of use, cost, and environmental impact.
Plaque Removal Efficiency
Traditional string floss is often considered the gold standard because its flexibility allows users to wrap it into a “C-shape” around the tooth. This technique is necessary for comprehensive cleaning, enabling the floss to slide slightly below the gumline and scrape the entire side of the tooth, effectively removing subgingival plaque. Using a fresh section of floss for each space also prevents transferring bacteria and debris.
In contrast, the small, taut segment of floss on a pick is held straight by the rigid plastic handle, making it difficult to achieve the curved “C-shape.” This limitation prevents the floss from adequately cleaning the entire tooth surface, especially below the gumline. Furthermore, using the same short piece of floss on the pick for multiple spaces risks spreading oral bacteria instead of removing it.
Maneuverability and Technique
String floss requires significant manual dexterity and a specific technique. Users must wrap about 18 inches of floss around their fingers, which can be awkward for those with limited hand mobility or arthritis. Mastering the control and tension needed to navigate the floss, especially to reach the back molars, presents a considerable learning curve. The process is often a two-handed operation, making on-the-go flossing less convenient.
Floss picks offer undeniable convenience due to their simple, one-handed operation and pre-threaded design. The handle provides a firm grip, making it easier for many users to access hard-to-reach areas, like the posterior teeth. This simplicity makes floss picks an accessible option for beginners, children, or individuals who struggle with the fine motor skills required by string floss. While control over tension and angle is limited, the ease of use can significantly increase the likelihood of consistent daily flossing.
Cost and Environmental Considerations
From an economic perspective, string floss is generally a more cost-effective option over time. A single container of string floss typically lasts for several months, making the cost per use very low. Floss picks, on the other hand, are single-use, disposable items, and a regular flosser may need to purchase multiple packs annually, leading to a higher long-term expenditure.
The environmental impact presents a clear distinction between the two tools. Floss picks are predominantly made of single-use plastic, generating significantly more waste compared to string floss. Although traditional string floss is often made of nylon or Teflon, its overall plastic volume and disposal frequency are much lower than that of picks. For those prioritizing sustainability, string floss offers eco-friendly options like silk or biodegradable materials, and some manufacturers now offer reusable floss pick handles with replaceable heads.
