Flossing is always important for a healthy smile, but when you wear Invisalign, proper timing is key. Since Invisalign trays fit snugly over your teeth, food particles and plaque can get trapped more easily, increasing the risk of cavities, bad breath, and gum irritation.
One of the most common questions orthodontic patients ask is:
"Should I floss before or after removing my Invisalign trays?"
In this guide, we’ll break down the answer, explain the best flossing routine, and show how a portable water flosser — like the KIWIBIRD Portable Water Flosser — can make the process simple and effective.
Why Flossing is Essential with Invisalign
When you wear aligners, your teeth are covered for most of the day. Without proper cleaning, bacteria and plaque can build up quickly.
Flossing benefits for Invisalign users:
-
Removes trapped food particles between teeth
-
Prevents plaque buildup under aligners
-
Reduces bad breath caused by bacteria
-
Protects gum health during orthodontic treatment
Quick Tip: Aim to floss at least once a day, preferably before bedtime.
Floss Before or After Removing Invisalign?
The best practice: Always floss after removing your aligners and before putting them back in.
Here’s why:
-
Flossing before removing trays is ineffective
The aligners block access to your gum line and teeth, preventing proper cleaning. -
Flossing after meals ensures aligners stay clean
This helps avoid trapping food debris under the trays. -
Prevents plaque buildup inside aligners
Bacteria thrive in warm, moist environments — like under Invisalign trays.
