Should You Floss Before or After Brushing?

December 26, 2025 9:00 am

Have you ever paused mid-routine and asked yourself whether you should floss before or after brushing? It’s one of those small habits that seems straightforward — yet even long-time patients at Alma Dental Care in Petaluma are surprised to learn the science behind the best sequence.

While the most important thing is that you’re flossing at all, research suggests there is a more effective order — and it’s worth paying attention to.

The Short Answer: Floss First

Brushing and flossing are both essential to keeping your teeth and gums healthy. But studies show that flossing before brushing is the more effective sequence for removing plaque and getting the most out of your fluoride toothpaste.

Here’s why:

  • Flossing first removes food particles and disrupts plaque between your teeth, making it easier for your toothbrush to reach those areas.
  • Brushing afterward helps sweep away loosened debris and delivers fluoride between the teeth, where it can strengthen enamel and fight decay.
  • If you brush first and floss second, you may be removing some of that beneficial fluoride before it has time to work effectively.

A 2018 study published in the Journal of Periodontology confirmed that this sequence — floss first, brush second — leads to greater plaque reduction and higher fluoride concentration between the teeth.

But Is It a Dealbreaker?

Not necessarily. If you’re consistently brushing twice a day and flossing once a day — regardless of the order — you’re doing your smile a big favor. The key is consistency, technique, and sticking with it.

What we’ve found at Alma Dental Care is that patients are more successful long-term when they build a habit that’s practical and repeatable. If flossing first makes you more likely to skip it entirely, it’s okay to do what works for you.

Tips for Building a Better Flossing Habit

  • Keep floss visible — leaving it on the counter or next to your toothbrush serves as a helpful visual cue.
  • Try floss picks or interdental brushes if string floss feels awkward or difficult to use.
  • Consider a water flosser — especially if you have bridges, dental implants, or sensitive gums.
  • Take your time — proper flossing takes about 1–2 minutes. Rushing through it won’t give you the full benefit.
  • Use a mirror — watching yourself floss can help with technique and prevent irritation or missed spots.

And remember, flossing isn’t just about preventing cavities — it’s one of the best things you can do to reduce gum inflammation and remove harmful bacteria where your toothbrush can’t reach.
