Clear Advice: The Right Way to Floss with Invisalign

Flossing with Invisalign is easy in theory—you just take your aligners out and get started. But doing it well is a different story. If you want your treatment to continue running on schedule and keep your oral health in top condition, flossing is non-negotiable. Continue reading to learn why flossing matters during Invisalign treatment, when you should do it, and how to do it correctly.

Why Flossing Is So Important

Cleaning your teeth is always important, but it can be doubly so during Invisalign treatment. Your trays create a snug seal over your smile, so any plaque or food particles left behind become trapped for hours. This warm, covered environment is like a greenhouse, but for bacteria. Flossing removes trapped buildup, helping to prevent:

• Cavities between your teeth
• Gum inflammation and bleeding
• Bad breath
• Stains that show through clear trays

Good flossing habits not only protect your oral health but also create a smoother, more comfortable treatment experience.

When Should You Floss with Invisalign?

So, do you have to floss all the time? Not at all! It’s not about flossing more often—it’s about flossing consistently. Once a day is enough for most people, and bedtime tends to be the easiest time to work it in. This way, you always remember, and you can go to sleep with a clean mouth before putting your aligners back on your teeth.

How to Floss with Invisalign Step by Step

Here’s a breakdown of how to floss using the proper techniques:

• Remove Your Aligners: Always take out your trays first and place them in their case.
• Measure Your Floss: Break off around 18 inches of floss (about the length of your forearm). Wrap it around your fingers loosely.
• Form a “C” Shape: Curve the floss around one tooth in a “C” shape and move it up and down along the side of each tooth and under your gumline.
• Move the String as You Go: Use a fresh section of floss for each gap, so you aren’t just moving plaque around.
• Rinse and Recheck: Rinse with water or mouthwash to clear away loosened debris before putting your aligners back in.
• Brush Your Teeth: Use a soft-bristled toothbrush and fluoride toothpaste to remove surface plaque. The reason to do this last is so you don’t rinse away the fluoride before it has a chance to do its job.

By making flossing a part of your Invisalign routine, you help ensure your treatment remains on track. When it ends, you won’t just have straighter teeth—you’ll have a healthier, cleaner smile you can be proud of.
