How to Floss with Invisalign: A Simple Guide for Healthy Smiles

July 24, 2025

Invisalign aligners make it easier than ever to straighten your teeth without the hassle of traditional braces. Since the trays are removable, you don’t have to work around brackets and wires to keep your smile clean. However, many patients underestimate just how important flossing is during Invisalign treatment.

Without proper oral hygiene, bacteria and food particles can get trapped between your teeth and aligners, leading to cavities, gum disease, and even bad breath. Knowing how to floss correctly will help you protect both your smile and your treatment results.

Why Flossing Is So Important with Invisalign

When you wear Invisalign aligners, your teeth are covered for most of the day—typically 20 to 22 hours. This creates an environment where plaque can build up quickly if teeth are not cleaned properly before reinserting trays. Brushing removes surface debris, but flossing is the only way to clean between teeth where toothbrush bristles can’t reach.

If food particles are left behind, they can get pressed against the enamel by the aligners, increasing the risk of tooth decay. Gum inflammation and bad breath are also more likely if flossing is skipped. By making flossing a part of your daily routine, you ensre your teeth stay healthy throughout treatment.

Tips for Flossing with Invisalign

Flossing during Invisalign treatment isn’t much different than flossing without aligners, but these tips can make the process more effective:

  • Always remove aligners before flossing. Never try to floss with your trays in place.
  • Floss after meals and snacks. This helps remove food particles before putting your aligners back in.
  • Use traditional dental floss or floss picks. Both work well—just be gentle to avoid injuring your gums.
  • Consider a water flosser. A water flosser can be a helpful addition for removing debris between teeth, especially if you’re on the go.
  • Don’t rush. Take your time to move the floss between each tooth, making a C-shape to clean thoroughly.

Building these habits ensures that your aligners stay clear and your teeth remain strong and healthy.

Building a Healthy Routine

The key to success with Invisalign is consistency—not just in wearing your aligners, but also in maintaining excellent oral hygiene. Flossing, along with brushing before reinserting trays, prevents problems that could slow down your treatment or affect your results.
