How to Clean Retainers

Introduction

Retainers collect bacteria, plaque, calcium deposits, and odors over time, especially when worn daily. Keeping them clean is essential for oral hygiene and to prevent discoloration or unpleasant smells. Fortunately, cleaning retainers is simple and can be done with basic household items without damaging the material.

What You'll Need

• Soft toothbrush

• Mild dish soap

• Cup of warm water

• Baking soda

• White vinegar

• Retainer cleaning tablets (optional)

• Cotton swabs for tight areas

Steps

Rinse the retainer under lukewarm water to remove loose debris. Avoid hot water, which can warp the material.
Apply a small drop of mild dish soap to a soft toothbrush and gently scrub all surfaces of the retainer. Pay special attention to grooves where plaque builds up.
Rinse the retainer thoroughly until all soap is removed.
For deeper cleaning, mix one teaspoon of baking soda with a cup of warm water and soak the retainer for 15–20 minutes. This helps remove odors and light staining.
Use a cotton swab or brush to clean any remaining buildup in crevices.
Let the retainer air dry completely before placing it back in its case to prevent bacterial growth.

Alternative Methods

• Dissolve a retainer cleaning tablet in warm water and soak the retainer according to package instructions.

• Use a white vinegar and water mixture (equal parts) for a 15-minute soak to break down mineral deposits.

• For heavy buildup, alternate between baking soda and vinegar soaks throughout the week.

What NOT to Do

• Do not use toothpaste; it is too abrasive and can scratch the retainer’s surface.

• Avoid soaking in mouthwash, especially if it contains alcohol, which can dry out or damage the material.

• Do not use boiling or hot water, which can warp plastic retainers.

• Avoid using bleach or harsh cleaners, as they can degrade the material and irritate your mouth.

FAQs

How often should I clean my retainer?

Clean your retainer once daily with mild soap and water. Perform a deeper soak once or twice per week.

Can I use toothpaste to clean my retainer?

No. Toothpaste is abrasive and can scratch the surface, causing bacteria to cling more easily.

Why does my retainer smell bad?

Odor is usually caused by trapped bacteria and dried saliva. Regular cleaning and allowing the retainer to dry fully can prevent this.

Can retainers go in the dishwasher?

No. High heat will warp or damage most retainers.
