Should You Floss Before or After Brushing?
Share
Short answer: floss first, then brush. That order gives a small but meaningful edge — flossing clears the tight spaces so your fluoride toothpaste can reach and protect more surfaces. That said, the real non-negotiable is doing both daily. If your current habit keeps you consistent, keep it. If you want the optimised route, switch to floss before brush.
Why the Order Matters
- Plaque first, polish second. Flossing lifts plaque and food from places bristles can't reach; then brushing removes what you've loosened.
- Fluoride where it counts. With those gaps cleared, your toothpaste's fluoride coats more tooth surface between teeth.
Flossing Before Brushing: The Small Advantages
- Cleaner finish: less interdental plaque left behind.
- Better fluoride access: toothpaste can actually reach those tight contacts.
- Fewer skip-it moments: doing floss first makes it harder to forget.
Flossing After Brushing: Still Absolutely Fine
If brushing then flossing is the only way you'll floss every day, stick with it — just rinse well so loosened debris doesn't linger.
The 2-Minute Night Routine (That You'll Actually Keep)
- Floss first. Glide gently and curve into a C-shape around each tooth.
- Brush second (2 minutes) with fluoride toothpaste. Spit, don't rinse — this keeps fluoride working on your teeth.
- Finish smart. If you use mouthwash, use it at a different time so you don't wash away fluoride immediately.
Busy night? Even 60 seconds of careful flossing beats skipping it entirely.
Technique Tips
- Go slow and light — snapping floss hurts gums and removes less plaque.
- Use a fresh section of floss for every gap.
- Replace brush heads every 3 months or sooner if bristles splay.
