Interdental cleaning is a necessary component of a comprehensive oral hygiene routine because a toothbrush cannot reach all surfaces of the tooth. Cleaning between the teeth helps prevent the accumulation of plaque, which can lead to gingivitis, periodontal disease, and cavities. The two most common tools for this task are dental floss and dental tape. The choice between them is primarily determined by the physical characteristics of the user’s mouth and the structural differences between the products.
Defining the Structural Differences
Dental floss is characterized by its thin, rounded profile. It is frequently composed of numerous strands of nylon twisted together, making it a “multifilament” material. Standard nylon floss can be either waxed or unwaxed; unwaxed floss is slightly thinner but more prone to shredding in tight spaces.
Dental tape, often referred to as ribbon floss, possesses a distinct geometry that is broader and flatter than traditional floss. It presents as a ribbon-like strip rather than a rounded cord, covering a greater surface area on the tooth with each pass. The material is often nylon, and its shape makes it stronger and less likely to snap compared to thinner nylon floss.
The difference in shape means dental tape is substantially wider across its cleaning surface, while dental floss is engineered to compress and slide into minimal spaces. Polytetrafluoroethylene (PTFE) floss, often called glide floss, is a distinct type of monofilament material. PTFE floss is extremely smooth and resistant to shredding, offering an alternative for tight contacts while retaining a thin profile.
Practical Application: Choosing Between Floss and Tape
The choice between dental floss and dental tape is dictated by the spacing between a person’s teeth. Due to its slender, rounded structure, dental floss is the preferred option for individuals with tightly spaced teeth. The thin strand compresses easily, allowing it to slide into narrow gaps without causing discomfort.
Dental tape is better suited for users who have wider-than-average gaps between their teeth. Its broader surface area is more efficient at cleaning the larger space. This wider material is also beneficial for cleaning around extensive dental work, such as bridges, crowns, or large fillings, often requiring fewer passes to remove debris and plaque.
Dental tape offers greater durability for those who struggle with floss fraying or tearing, especially when navigating rough edges or existing dental restorations. PTFE floss is also highly recommended in these situations because its single-strand construction resists shredding better than traditional multifilament nylon floss. Ultimately, the most effective tool is the one that fits comfortably and is used consistently to ensure interdental surfaces are cleaned daily.
