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:

  1. Use a soft toothbrush

  2. Apply non-abrasive toothpaste

  3. Gently brush all surfaces

  4. 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
