The Best Ways to Clean Retainers in 2025

Deep cleaning is essential to remove stains, tartar, and deep bacteria. Here are the top methods:

1. Retainer Cleaner Tablets (Most Convenient)

Using retainer cleaner tablets is a hassle-free method that’s rising in popularity. Simply drop the tablet in water, soak your retainer, and rinse.

Best for: Busy people, Invisalign users, clear retainers

Pros:

2. Ultrasonic Retainer Cleaners (High-Tech Solution)

An ultrasonic retainer cleaner uses high-frequency sound waves to vibrate and remove dirt particles from hard-to-reach areas.

Best for: People with bonded retainers or aligners with deep grooves

Pros:
