How to Clean Your Retainers Properly: Simple Tips for Freshness and Longevity
After completing your orthodontic treatment with clear aligners or braces, your retainer becomes your most important tool for keeping your smile straight. But just like your teeth, your retainer needs daily care to keep it clean, fresh, and effective. Cleaning your retainers properly ensures not only good oral hygiene but also extends the life of the retainer itself. Let’s break down the best methods for keeping your retainers clean, what to avoid, and why consistency matters.
Why Cleaning Your Retainer Matters
Your retainer sits in your mouth for hours every day—collecting saliva, plaque, and bacteria. If not cleaned regularly, this can lead to:
Bad breath
Bacterial buildup
Staining or discoloration
Risk of cavities or gum irritation
Premature breakdown of the retainer material
Proper care prevents these issues and ensures your retainer continues doing its job: maintaining your aligned smile.
The Easiest Way to Clean Your Retainers: Toothbrush & Toothpaste
The most cost-effective and convenient method is the brush-and-rinse routine:
✅ Every time you remove your retainer:
Use a soft toothbrush
Apply non-abrasive toothpaste
Gently brush all surfaces
Rinse thoroughly under lukewarm water (never hot)
This should be done at least twice a day—and ideally, every time you take your retainer out of your mouth.
Pro Tip:
Brush your retainers at the same time as your teeth—it’ll become second nature.
Deep Cleaning Options: Invisalign Cleaning Crystals
If you want a deeper, more thorough clean, especially once or twice a week, Invisalign offers cleaning crystals designed specifically for clear plastic appliances.
How they work:
Dissolve the crystals in lukewarm water
Soak your retainer for 15–30 minutes
Rinse and brush before reinserting
Benefits:
Removes bacteria, odors, and buildup
Keeps retainers clear and fresh
Safe for Invisalign and Vivera retainers
These cleaning systems come at an extra cost, but they’re highly effective—particularly for long-term maintenance.
Other Natural & Affordable Cleaning Options
If you don’t have access to cleaning crystals, there are other safe and simple at-home alternatives:
Antibacterial soap & water – gentle, effective, and affordable
White vinegar + water soak (1:1) – great for removing buildup (rinse thoroughly after)
Hydrogen peroxide + water (1:1) – helps kill bacteria (use occasionally, not daily)
Baking soda paste – helps remove odors and surface stains
Avoid:
❌ Boiling water (warps the plastic)
❌ Mouthwash with alcohol (can damage material)
❌ Abrasive toothpaste or hard brushes (can scratch the surface)
Cleaning Tips for All Retainer Types
Whether you’re using a clear removable retainer (like Vivera or Essix) or a fixed/bonded retainer, maintenance is essential:
For clear plastic retainers:
Clean daily with gentle brushing
Store in a case when not in use
Avoid hot water and harsh chemicals
For fixed (bonded) retainers:
Floss carefully around the wire
Use interdental brushes or floss threaders
Visit your dentist regularly to check for buildup or wear
