Dental Floss Q&A: Expert Tips That Will Change How You Think About Oral Hygiene

I remember using a thread to clean the spaces between my teeth as a kid. Later, when I became a dentist, I learned it is called ‘dental floss’.

Check yourself: do you or your family members floss daily? For most of you, the answer will be ‘No’. I know it. 

When patients come to me with dental issues, especially small children, I guide their parents to adopt healthy habits in children like brushing their teeth twice, rinsing their mouth after eating something and doing dental floss at least once a day.

Many people are unaware of dental floss and ask different questions in the consulting room. Hence, today, through this blog, I will clear up all your doubts about dental floss.  

Basics of Dental Floss

What is dental floss?

Dental floss is a thin, soft thread made of nylon or plastic designed to clean between teeth and along the gumline where a toothbrush can’t reach. It removes food particles and plaque, helping maintain oral health.

Why is flossing important?

Flossing is crucial because it removes plaque and food debris from areas that brushing alone cannot clean. Regular flossing helps prevent cavities, gum disease, and bad breath.

How often should you floss?

You should floss at least once a day, ideally before bedtime. This ensures food particles and plaque don’t accumulate overnight, keeping your teeth and gums healthy.

What are the different types of dental floss?

  • Waxed floss: Coated for smoother movement between tight teeth.
  • Unwaxed floss: Thinner and uncoated, great for closely spaced teeth.
  • Dental tape: Broader and flatter, ideal for those with larger gaps.
  • Floss picks: Convenient and easy-to-use pre-threaded tools.
  • Water flossers: Devices that use a water stream to clean between teeth.

Is flossing necessary if I brush regularly?

Yes, flossing is necessary, even with regular brushing. Brushing cleans the tooth surfaces, but only flossing can effectively remove plaque and debris from between teeth and below the gumline.

What's the difference between waxed and unwaxed floss?

  • Waxed floss: Glides easily through tight spaces, thanks to its coating. It is slightly thicker but more durable.
  • Unwaxed floss: Thinner and better for tight teeth but prone to shredding. It may offer a better grip for some users.

Flossing Techniques

How do you floss correctly?

To floss correctly:

  • Take about 18 inches of floss and wrap it around your middle fingers.
  • Hold the floss taut with your thumbs and index fingers.
  • Gently slide the floss between your teeth.
  • Curve it into a C-shape around each tooth and gently move it up and down.
  • Avoid snapping the floss to prevent gum injury.

What's the proper technique for flossing?

The proper technique involves sliding the floss gently between teeth, curving it around each tooth, and moving it below the gumline. Clean each tooth side with a fresh section of floss.

Should you floss before or after brushing?

It’s best to floss before brushing. Flossing first removes plaque and debris, allowing fluoride from the toothpaste to reach more areas effectively.

How long should flossing take?

Flossing should take about 2–3 minutes to clean your teeth thoroughly. Take your time to ensure every space is cleaned.

Is there a right way to hold dental floss?

Yes, with about an inch of taut floss, hold dental floss between your fingers. Use your thumbs for the upper teeth and index fingers for the lower teeth to guide the floss precisely.

Can you floss too much?

Yes, aggressively over-flossing can damage gums, causing irritation, recession, or bleeding. Once a day is sufficient for maintaining oral health.

How do you floss with braces?

To floss with braces:

  1. Use a floss threader or orthodontic floss.
  2. Thread the floss under the wire and gently clean between teeth.
  3. Curve the floss around each tooth and move it gently up and down.
  4. Take care not to damage wires or brackets.

What's the best way to floss around dental implants?

Use implant-specific floss or a floss threader:

  1. Thread the floss under the implant bridge or crown.
  2. Slide it gently back and forth to clean.
  3. Avoid snapping or aggressive motions to protect the implant.
    Water flossers can also be an excellent alternative.

Types of Dental Floss

What is mint-flavored dental floss?

Mint-flavored dental floss is coated with a mint essence, offering a refreshing taste while cleaning between teeth. It makes the flossing experience more enjoyable, encouraging regular use.

Are there biodegradable floss options?

Yes, biodegradable floss options, like those made from silk or plant-based materials, are eco-friendly and decompose naturally. They are a sustainable alternative to traditional plastic-based floss.

What is unwaxed floss used for?

Unwaxed floss is ideal for people with closely spaced teeth. It is thinner, allowing it to slide easily between tight gaps. However, it may shred more easily compared to waxed floss.

What's the difference between nylon and PTFE floss?

  • Nylon floss: Made of multiple strands, it is strong but can shred in tight spaces.
  • PTFE floss: Single-strand and more durable, it glides smoothly between teeth and resists shredding.

What is a dental tape?

Dental tape is a broader, flatter type of floss, ideal for people with larger gaps between their teeth. Its shape provides better coverage and ease of use for certain users.

Are there eco-friendly floss alternatives?

Yes, eco-friendly alternatives include:

  • Silk floss (biodegradable and plastic-free)
  • Bamboo fibre floss
  • Compostable floss picks
  • Water flossers (reduce waste entirely)

What is expanding floss?

Expanding floss is designed to stretch and widen as it contacts moisture in the mouth. This allows it to adapt to different gap sizes, providing effective cleaning while being gentle on gums.

Flossing Tools and Accessories

What are floss picks?

Floss picks are small, plastic tools with a short piece of floss attached to a handle. They are convenient for quick flossing, especially when you’re on the go, and are easy to use for those with limited dexterity.

How do water flossers compare to traditional floss?

Water flossers use a stream of water to remove plaque and food debris. They are gentler on gums and easier for people with braces, implants, or dexterity issues, but traditional floss is better for physically scraping plaque off teeth surfaces.

Are interdental brushes better than floss?

Interdental brushes can be more effective than floss for cleaning larger gaps between teeth or around braces. However, floss is better for tight spaces. Both tools can complement each other in an oral hygiene routine.
