Flossing removes plaque and food particles from between teeth and along the gumline, a practice important for oral hygiene. However, floss often gets stuck or shreds during use. This issue can signal underlying dental conditions or indicate that flossing habits need adjustment, impacting cleaning effectiveness.
Common Dental Factors
Several dental conditions can cause floss to snag or shred. Teeth that are naturally close together or have shifted can create tight contact points, making flossing difficult. Decay, especially between teeth, creates rough surfaces that catch floss fibers. Rough or poorly contoured dental restorations, such as old fillings, crowns, or veneers, can also snag floss. An “overhang” where filling material extends beyond the tooth’s natural contour, or chips and fractures in enamel, are frequent causes.
Calculus, also known as tartar, is another frequent cause. This hardened plaque creates a rough surface on teeth that can trap and shred floss. Tartar cannot be removed by brushing or flossing alone and requires professional dental cleaning. Gum recession can also expose tooth root surfaces, which are covered by cementum. This material is rougher than enamel, increasing the likelihood of floss catching.
Floss Type and Technique Considerations
The type of floss and flossing method significantly influence whether it gets stuck. Different floss materials vary in their tendency to shred. Unwaxed floss, for example, may fray more than waxed varieties in tight spaces. Some flosses are more susceptible to shredding due to thinness or lack of tensile strength. Natural fibers like cotton or bamboo often have shorter fibers, contributing to easier shredding.
Improper flossing technique is another common factor. Forcing floss between teeth with excessive pressure can cause it to break or fray. If floss is not wrapped correctly around the tooth in a C-shape, it may not glide effectively and could become trapped. Using the same section of floss for multiple interdental spaces can also lead to its deterioration and shredding.
Strategies for Smooth Flossing
To prevent floss from getting stuck, select the appropriate type. Waxed floss or those designed to glide, such as polytetrafluoroethylene (PTFE) floss, navigate tight spaces more easily and are less likely to shred. Dental tape, which is wider and flatter, can also be effective. For very tight contacts, a thinner floss or a water flosser might be considered.
Mastering proper technique is important. Gently guide floss between teeth using a light sawing motion, rather than snapping it forcefully. Once through the contact point, curve the floss around each tooth in a C-shape and slide it gently up and down, cleaning below the gumline. If floss consistently gets stuck, or if you notice rough spots, persistent bleeding, or pain, a dental visit is advisable. A dentist can identify and address underlying issues like calculus buildup, faulty restorations, or decay, ensuring a smoother, more effective flossing routine.
