SmileAgain Retainer Cleaner 22 Pack - 6 Month Supply Mint

Our review of the SmileAgain Retainer Cleaner finds it best for people who wear clear aligners, retainers, dentures or mouth guards and want a low-effort way to remove stains and odors. The single biggest reason to buy is the concentrated cleaning crystals: one packet dissolves to maintain a clean solution for up to 7-10 days, delivering roughly 180-220 cleanings from the 22-pack and making it convenient for travel or daily maintenance. It is a practical choice for anyone who needs strong stain removal without bleach or chlorine.

Key Features

• Long-lasting packets: Each cleaning crystal packet preserves the cleanliness of the solution for 7-10 days, reducing the need to mix fresh solution every day.
• High concentration formula: The formula is designed to remove stains, calcium and tartar while being effective across multiple oral appliances.
• Broad appliance compatibility: Works on clear aligners, retainers, dentures, mouth guards and night guards without softening or making them brittle.
• Antimicrobial action: Kills 99.9% of odor-causing bacteria and pathogens, including Candida albicans, helping reduce odor and oral film buildup.
• Mint flavor and easy use: Mint-flavored crystals dissolve quickly for a pleasant smell and simple soak routine: stir, dissolve, soak 20 minutes and rinse.

Who It's For

The SmileAgain Retainer Cleaner is ideal for daily users of removable oral appliances - people with clear aligners, retainers or night guards who want a strong cleaning product that tackles coffee, tea, nicotine and calcium stains. It also fits denture wearers who need a travel-friendly, non-bleach cleaner that restores appearance and helps reduce odor.

Those who should look elsewhere include users seeking a one-time single-use tablet system or those who prefer a scented gel or foam; this product is a concentrated powder/crystal meant for repeated soak solutions rather than an instant spray cleaner.
