In What Order Should You Brush, Floss, and Use Mouthwash? Many People Do It in the Wrong Order
Maintaining good oral hygiene isn’t just about what you do—it’s also about when you do it. Brushing, flossing, and using mouthwash are the three pillars of daily dental care, yet many people unknowingly do them in the wrong order. That simple mistake can reduce how effective your routine really is.
So, what’s the correct order—and why does it matter? Let’s break it down step by step.
The Correct Order: Floss → Brush → Mouthwash
Dental professionals generally recommend the following sequence:
- Floss first
- Brush second
- Use mouthwash last (with one important exception explained below)
This order allows each step to work at its maximum effectiveness.
Step 1: Floss First – Clean Where Brushes Can’t Reach
Flossing before brushing may feel counterintuitive, but it’s actually the most effective approach.
Why floss first?
- Removes food particles and plaque from between teeth
- Loosens bacteria hiding below the gumline
- Opens up tight spaces so toothpaste can reach them during brushing
When you floss first, you’re clearing the way for fluoride toothpaste to better protect those hard-to-reach areas.
Tip: Use gentle, curved motions around each tooth to avoid irritating your gums.
Step 2: Brush Second – Strengthen and Protect Teeth
Brushing after flossing allows fluoride from your toothpaste to coat more surfaces of your teeth.
Best brushing practices:
- Brush for two full minutes
- Use a soft-bristled toothbrush
- Hold the brush at a 45-degree angle toward your gums
- Use small circular motions, not harsh scrubbing
Brushing after flossing ensures that loosened debris is fully removed and that fluoride can do its job strengthening enamel.
Step 3: Mouthwash Last – Freshen and Rinse (Most of the Time)
Using mouthwash at the end helps:
- Wash away remaining bacteria
- Freshen breath
- Reach areas brushing may miss
However, not all mouthwash is the same.
Important Exception: Fluoride Mouthwash
If you use a fluoride mouthwash, timing matters.
Option A: Skip mouthwash immediately after brushing
If your toothpaste already contains fluoride, rinsing right away with mouthwash can wash it off too soon.
Option B: Use fluoride mouthwash at a different time
Many dentists recommend using fluoride mouthwash:
- At a different time of day, or
- 30 minutes after brushing
This allows fluoride from toothpaste to stay on your teeth longer and work more effectively.
The Most Common Mistakes People Make
Many people unknowingly weaken their oral care routine by:
- Brushing before flossing
- Using mouthwash immediately after brushing with fluoride toothpaste
- Rinsing with water right after brushing
- Brushing too hard or too quickly
Each of these habits can reduce fluoride exposure and leave plaque behind.
Does the Order Really Matter?
Yes—studies and dental associations consistently show that flossing before brushing improves plaque removal and fluoride retention. Over time, this can lead to:
- Fewer cavities
- Healthier gums
- Less plaque buildup
- Fresher breath
Small changes in routine can make a big difference in long-term oral health.
A Simple Daily Oral Care Routine
Here’s an easy routine to follow twice a day:
- Floss thoroughly
- Brush with fluoride toothpaste for 2 minutes
- Spit, don’t rinse with water
- Use mouthwash later if it contains fluoride, or immediately if it’s non-fluoride
Final Thoughts
Many people brush, floss, and rinse every day—but doing it in the wrong order can limit the benefits. By simply switching to floss first, brush second, mouthwash last, you can significantly improve your oral hygiene without adding any extra time.
Your smile—and your dentist—will thank you. 😁
