Can Invisalign Cause Bad Breath?
Wearing Invisalign is one of the most popular ways to straighten teeth without traditional braces. But many patients are surprised when they notice bad breath while using Invisalign aligners. Is it the treatment itself, or how you care for your aligners? Let’s break it down.
Why Invisalign Might Cause Bad Breath
Bad breath (halitosis) during Invisalign treatment usually comes down to bacteria, food particles, and poor cleaning habits. Here are the main causes:
-
Trapped bacteria – Clear aligners fit snugly over teeth, creating a sealed environment where bacteria can grow.
-
Poor cleaning – If aligners are not cleaned properly, odor builds up quickly.
-
Dehydration – Wearing aligners can reduce saliva flow, which normally helps clean your mouth.
-
Diet choices – Coffee, onions, garlic, and sugary foods stick to aligners and make odors worse.
How to Prevent Bad Breath With Invisalign
Keeping your aligners clean is the key to avoiding odor. Here are the best ways to clean retainers and Invisalign trays:
1. Daily Rinse and Gentle Brushing
-
Rinse aligners with lukewarm water every time you remove them.
-
Use a soft toothbrush (no toothpaste, as it can scratch).
2. Use an Invisalign Cleaner
Specialized cleaners break down plaque and odor-causing bacteria. Two popular choices are:
-
Invisalign Cleaning Crystals – Designed by Invisalign to keep trays clear and fresh.
-
Weiss Naturals Cleaning Tablets – A persulfate-free option that keeps retainers clear, odor-free, and safe.
3. Try an Ultrasonic Retainer Cleaner
Ultrasonic cleaners like Zima Dental Ultrasonic Cleaner use vibrations to remove deep buildup. When paired with a cleaning tablet, they provide maximum freshness.
4. Maintain Oral Hygiene
-
Brush and floss before reinserting aligners.
-
Drink plenty of water to keep your mouth hydrated.
