Description
Dental floss is a specialized cord of thin filaments used to remove food debris and dental plaque from the interproximal surfaces (the tight spaces between teeth) where a standard toothbrush cannot reach. It is a fundamental tool in preventive dentistry, designed to clean the “contact points” between teeth to prevent the formation of cavities and periodontal disease.
Key Features
- Material Variety: Available in various materials including Nylon (multifilament), which may fray or tear in tight contacts, and PTFE (monofilament), which is shred-resistant and slides easily between crowded teeth.
- Coatings: Often coated with wax to improve lubricity and glide, or left unwaxed for a “squeaky clean” feel that some clinicians prefer for better grip against the tooth surface.
- Textural Options: Ranges from thin Dental Tape (flat and wide for large gaps) to Expanding Floss (which puffs up when in contact with saliva to clean larger surface areas).
- Flavoring & Additives: Frequently infused with mint for freshness, or therapeutic agents like Fluoride or Xylitol to aid in remineralization and bacteria inhibition.
- Tensile Strength: Engineered to be strong enough to resist snapping while being thin enough to pass through the tightest anatomical contacts.
Usage
- Interproximal Cleaning: Specifically used to disrupt the biofilm (plaque) located below the gum line and between the teeth.
- C-Shape Technique: Users are instructed to wrap the floss in a “C” shape around the neck of the tooth and move it vertically to scrape the tooth surface effectively.
- Preventive Care: Regularly used to prevent interproximal caries (cavities between teeth) and gingivitis by removing irritating debris from the sulcus.
- Restorative Check: In clinical settings, dentists use floss to check the “contacts” of new fillings or crowns to ensure they are neither too tight (preventing cleaning) nor too loose (causing food impaction).
- Appliance Maintenance: Used with floss threaders to clean under fixed orthodontic braces, dental bridges, and permanent retainers.
