Is Flossing Really Necessary? What Dentists Want You to Know.

Is Flossing Really Necessary?

If you’ve ever wondered, “Do I really need to floss every day?” you’re not alone. Some recent headlines and studies suggest that the scientific evidence for flossing isn’t as strong as once thought. But here’s what dentists want you to know: flossing remains an essential part of oral care. Flossing is not just about fresh breath; it’s important for preventing gum disease, tooth decay, and protecting your smile, especially if you’re using Invisalign or other orthodontic appliances. 

The Dental Case for Flossing

Your toothbrush does a lot, but it can’t reach the tight spaces between teeth or just under the gumline. That’s where plaque, bacteria, and food debris linger. If these are not removed, they can turn into tartar, which only a professional dental cleaning can remove, inflame your gums, or eventually lead to more serious gum disease.

Studies show that when people add flossing, or other similar clearing methods, to brushing, they tend to have less gingivitis and fewer plaque-related problems than brushing alone. Dentists generally recommend flossing at least once per day.

What About Invisalign & Flossing?

If you’re undergoing Invisalign treatment, flossing becomes even more important. Because your aligners cover your teeth for many hours per day, any food or plaque trapped between teeth has a greater chance to stay there, under the trays, which can lead to cavities, bad breath, gum irritation, or stains.

Here are a few best practices dentists suggest for flossing when you have Invisalign:

  • Always remove your aligners before flossing or brushing. Clean your teeth before putting them back in.
  • Floss at least once daily, ideally right before bed. Invisalign patients should also floss after meals when possible.
  • Use a gentle technique. Curve the floss in a “C” shape around each tooth, sliding below the gum line gently rather than snapping or forcing. For tight spaces or difficulty, consider floss threaders, waxed floss, or between-teeth brushes/water flossers. 

Common Concerns & Misconceptions

  • “No strong long-term studies”: True. Some recent analyses point out that evidence is modest, especially for long-term outcomes. But lack of perfect studies doesn’t mean flossing has no value. The biological logic, clinical experience, and shorter‐term trials all support it.
  • Pain, bleeding, or discomfort: Often a sign of incorrect technique or waiting too long between cleanings. Being gentle, using the right tools, and regular dental checkups help alleviate these issues.
  • “Maybe brushing is enough”: For many people, brushing is good, but not enough, especially when you have crowded teeth, overlapping teeth, or appliances like Invisalign. The bits that brushing misses are where floss gets the job done. 

How to Make Flossing Work For You

  1. Pick a time when you can consistently do it: flossing at night tends to work best for most people.
  2. Choose floss tools that suit your mouth: traditional floss, waxed floss, floss picks, or water flossers. Use a tool you’ll actually stick with.
  3. Practice proper flossing technique: insert between teeth gently, curve around each tooth, slide up and down, and be gentle on gums.
  4. With Invisalign, floss before wearing aligners, clean aligners regularly, and avoid letting food residue sit under trays.

Flossing might feel like an extra chore, especially if you already brush, but most dentists agree it’s far from optional. It plays a key role in keeping gums healthy, preventing decay, and making sure your orthodontic or cosmetic treatments, like Invisalign and whitening, deliver their best results without complications.
