Water Flosser vs. String Floss: Which Cleans Better?

Brushing cleans most of your tooth surfaces, but it cannot reach the tight spaces between teeth. That is where plaque hides and where many cavities and gum problems start. Cleaning between your teeth every day is essential, but which tool should you use: a water flosser vs floss?

Let’s compare the water flosser vs. floss so you can choose the option you will actually stick with.

How String Floss Works

Traditional string floss is a thin strand you slide between your teeth and curve around each tooth in a “C” shape. It physically scrapes plaque off the tooth surface and just below the gumline.

Pros of string floss:

• Very effective at scraping sticky plaque from tooth surfaces
• Inexpensive and easy to carry anywhere
• No electricity, water, or counter space needed

Cons of string floss:

• Takes practice to use correctly
• Hard for people with limited hand dexterity or arthritis
• Difficult to use with braces, bridges, or implants

How a Water Flosser Works vs. Floss

A water flosser (sometimes called an oral irrigator) sprays a steady, pulsing stream of water between teeth and along the gumline to flush out food and bacteria.

Pros of a water flosser:

• Easy to use, especially for people with braces, implants, bridges, or limited dexterity
• Gentle on sensitive or bleeding gums
• Studies show water flossers can reduce gum bleeding and inflammation
• Many people find it more pleasant, so they use it more consistently

Cons of a water flosser:

• Costs more than floss and needs replacement tips
• Needs counter space and an outlet or charging
• May be less effective at scraping stubborn, sticky plaque than well-used string floss

Water Flosser vs. Floss: Which Is Better?

Both are effective when used correctly and consistently. The best choice depends on your mouth and your habits:

• Choose string floss if you have healthy gums, no dental work in the way, and you already floss well.
• Choose a water flosser if you have braces, implants, bridges, crowns, arthritis, or gums that bleed easily.
• Use both for the most thorough clean: string floss to scrape plaque, and a water flosser to flush out the rest.

The most important thing is that you clean between your teeth every day. The best tool is the one you will use.

Tips for Better Flossing

• Floss once a day, ideally before bedtime.
• With string floss, hug each tooth in a “C” shape and gently go just under the gumline.
• With a water flosser, start on a low setting and aim the tip at the gumline at a 90-degree angle.
• Some bleeding at first is normal. If it lasts more than two weeks, read our guide to bleeding gums and see your dentist.
• Keep up with professional cleanings to remove tartar that no home tool can remove. Learn more about tartar on teeth.

Frequently Asked Questions

Can a water flosser replace flossing?

For many people, yes, especially those with braces or dental work. Ask your dentist what is best for your situation.

Should I floss before or after brushing?

Either works. Flossing first can help fluoride from your toothpaste reach between your teeth.

Are interdental brushes a good option?

Yes. Small interdental brushes work well for people with larger gaps between their teeth.
