Can a Dentist Tell If You Don’t Floss? The Truth About Skipping Flossing

Written by Williams, Daily & Frazier | May 14, 2025 12:00:00 PM

It’s the question almost everyone thinks but rarely asks out loud:
Can my dentist actually tell if I don’t floss?

Spoiler alert: Yes, we can. But this blog isn’t here to guilt-trip you, it’s here to explain why flossing matters, what dentists really notice, and how even small improvements to your dental routine can make a big difference in your long-term oral health.

At Williams, Daily & Frazier Dental in Raleigh, NC, we want you to feel confident, not confused, when it comes to your dental care. This guide breaks down the basics of dental crowns, when you might need one, and how they can protect your teeth for the long haul.

Whether you’re new to flossing or have been avoiding it for years, here’s what you need to know, straight from your friendly dental team in Raleigh, NC.

What Happens When You Don’t Floss

Brushing your teeth twice a day is a solid start, but it only reaches about 60% of your tooth surfaces. The remaining 40%? That’s what floss is for.

When you skip flossing, plaque, food particles, and bacteria build up between your teeth and along the gumline. Over time, that buildup can lead to:

  • Bad breath
  • Cavities between teeth
  • Gum inflammation (gingivitis)
  • Periodontal disease
  • Tooth loss (if left untreated)

And here’s the thing: even if you’re brushing and using mouthwash, those tight spaces between your teeth still need attention.

So... Can a Dentist Tell? Absolutely.

At Williams, Daily & Frazier Dental, we’ve seen thousands of smiles, and it’s pretty easy to spot the signs when flossing is missing from the routine.

Here’s what we look for:

  • Bleeding gums during your cleaning: If your gums bleed easily, especially when we floss between your teeth during an exam, that’s a major red flag. Healthy gums don’t bleed just from gentle flossing.
  • Swollen or inflamed gum tissue: Plaque that’s left untouched causes irritation. Over time, this leads to puffiness, redness, and tenderness.
  • Tartar between your teeth: Plaque that stays between your teeth hardens into tartar. Once it’s there, you can’t remove it with a toothbrush—it requires a professional cleaning.
  • Cavities in hard-to-reach areas: Most cavities from poor flossing happen between the teeth, where your brush just can’t reach.

So yes, we can tell if you’ve been skipping. But we’re not here to judge. We’re here to help you improve and avoid long-term issues.

Why Flossing Matters More Than You Think

Flossing isn’t just about removing spinach from your smile (although that helps). It’s about disrupting the bacteria colonies that grow between your teeth.

According to the American Dental Association, flossing daily plays a key role in preventing tooth decay and gum disease. When combined with brushing, it helps remove plaque and food particles that can cause irritation, infection, and long-term damage.

It’s a small investment of time (less than two minutes a day!) that pays off in healthier gums, fewer cavities, and fresher breath.

How to Make Flossing a Habit

Like any habit, flossing takes a little time to stick, but it gets easier (and more rewarding) the more you do it.

Tips to build the habit:

  • Floss at the same time every day, right before bed works well for most people.
  • Keep floss in plain sight, on your bathroom counter or near your toothbrush.
  • Use a habit tracker or set a recurring phone reminder.
  • Be gentle, bleeding is common at first, but it usually stops after a few days of consistent flossing.

Stick with it for a week or two, and you’ll notice fresher breath, healthier gums, and a more confident smile.

What to Do If You Struggle With Flossing

We get it, not everyone loves flossing. Some people find it awkward. Others struggle with tight teeth or sensitive gums. Here are a few alternatives and tips that make flossing easier:

1. Use a Water Flosser

Water flossers (like the Waterpik®) use pulsating streams of water to clean between your teeth. They’re gentle, effective, and especially helpful for people with braces or bridges.

2. Try Pre-threaded Floss Picks

Floss picks are a great option if traditional string floss feels like too much of a hassle. Keep a few in your car, desk, or bag for easy access.

3. Use Waxed Floss for Tight Teeth

If your teeth are close together, waxed floss can slide more comfortably.

4. Be Gentle and Consistent

You don’t need to floss aggressively, just once a day, with gentle pressure, is enough to see results.

Consistency Is More Important Than Perfection

If you haven’t flossed in years, that’s okay. The best time to start was yesterday. The second-best time is today.

Your gums might bleed a bit when you start, but that’s a sign they’re healing. Within a week or two of regular flossing, you’ll likely see:

  • Less bleeding
  • Fresher breath
  • Less plaque at your next dental visit
