Should You Floss Before or After Brushing?

Dec 11

Flossing and brushing are both crucial steps in maintaining oral health — but does the order matter? This article explores whether you should floss before or after brushing based on dental research, and how smart toothbrushes like BrushO can help you build the ideal routine for maximum plaque removal and gum protection.

Should You Floss Before or After Brushing?

Oral hygiene isn’t just about brushing twice a day — it’s about doing things in the right order to maximize effectiveness. One of the most common questions people ask is: Should I floss before or after brushing? The answer might surprise you.

🧪 What Does Research Say?

Several dental studies have explored the impact of the order of flossing and brushing. According to a study published in the Journal of Periodontology, flossing before brushing results in more plaque removal and better fluoride retention from toothpaste.

Why Flossing First Works Better:

 • Removes debris first: Flossing dislodges food particles and plaque between the teeth, making brushing more effective afterward.
 • Allows fluoride to penetrate: Brushing after flossing lets fluoride reach between the teeth, strengthening enamel.
 • Reduces bacterial buildup: Flossing first reduces the chance of bacteria being pushed deeper by the toothbrush.

🪥 What Happens If You Brush First?

Brushing first is not “wrong,” but it might be less effective. If you brush before flossing:

 • Fluoride may not reach between teeth due to lingering plaque.
 • You may skip flossing altogether because your mouth already feels “clean.”
 • You might push food particles deeper with the floss, which is counterproductive.
