If you’re using Invisalign®, keeping them clean is essential for ensuring effective treatment and maintaining your confident smile. While these clear aligners are designed to be nearly invisible, improper or inadequate care can cause them to become cloudy or accumulate bacteria, compromising both your oral hygiene and the aesthetic appeal of your aligners. That’s why choosing the right Invisalign cleaner and adopting good cleaning practices is crucial for anyone undergoing this teeth-straightening journey. In this guide, we’ll explore the best cleaning solutions available and share tips on how to care for your Invisalign trays, ensuring the best results for your smile.

Why It’s Important to Clean Your Invisalign Aligners
Wearing Invisalign for 20 to 22 hours a day means your aligners are constantly exposed to saliva, food particles, and bacteria. Since Invisalign is removable, you have the advantage of easily taking them out for thorough cleaning, ensuring they remain hygienic and clear. Otherwise, these virtually invisible trays can become stained, develop an odour, or lead to oral health issues such as plaque buildup and gum disease. By cleaning your aligners daily, you can:
- Prevent bacteria and plaque accumulation
- Keep your aligners odour-free
- Ensure your aligners remain transparent
- Preserve your overall oral hygiene
Best Invisalign Cleaners on the Market
There are various products available for cleaning Invisalign, each with its own advantages based on your needs, budget, and preferences. Choosing the right cleaner will keep your trays looking fresh and feeling comfortable throughout your treatment. Here are some top options to consider:
1. Invisalign Cleaning Crystals
Specifically designed for Invisalign aligners, these cleaning crystals offer a reliable and effective solution. By dissolving the crystals in lukewarm water and soaking your trays, they help remove bacteria, plaque, and built-up residue, keeping your aligners clear and fresh. The main drawback is their higher price point compared to other methods. However, their dedicated purpose as Invisalign-specific cleaners ensures effectiveness in maintaining both hygiene and clarity, making them a trusted and preferred choice for many.

2. Retainer Cleaning Tablets
Retainer cleaning tablets are a popular option that work well with Invisalign trays. These tablets typically dissolve in water, releasing bubbles that help break down stains, eliminate odours, and disinfect your aligners. Quick, easy to use, and affordable, they offer a convenient solution for daily cleaning. However, while effective for general maintenance and preventing plaque buildup, they may not be as suited for tackling more stubborn or heavy stains.

3. Ultrasonic Cleaners
Ultrasonic cleaners are devices that use sound waves and a cleaning solution to clean dental appliances, including Invisalign trays. The sound waves create tiny bubbles that effectively remove plaque, bacteria, and debris, reaching areas that traditional cleaning methods may miss. Ultrasonic cleaners are highly efficient and provide a deeper clean compared to manual methods. However, these devices are generally more expensive than other cleaning options and may be considered a luxury item for those seeking a premium cleaning solution.

What Not to Use on Your Invisalign Aligners
While maintaining a cleaning routine is essential, you should avoid:
- Toothpaste: Toothpaste with beads agent can be too abrasive and can scratch the surface of your aligners, making them more visible.
- Mouthwash: Coloured mouthwashes, especially those containing alcohol, can stain your trays and reduce their clarity.
- Hot Water: Heat can warp the plastic and compromise the fit of your aligners. Always use lukewarm or cold water for rinsing or soaking.
- Bleach: Bleach can weaken the plastic and distort the fit of your trays.
- Other DIY agents/alternatives: Some common options include denture cleaning tablets, baking soda, or vinegar. These options may lead to unwanted side effects such as accidental damage. As such, we recommend using products specifically designed for cleaning.
Best Practices for Cleaning Your Invisalign Aligners
Using the right cleaner is important, but there are additional steps you can take to ensure your Invisalign trays stay in the best condition throughout your treatment.
- Rinse regularly: Rinse your aligners with water whenever you remove them, especially before eating. This helps wash away saliva and food particles, preventing plaque buildup.
- Brush gently: You may consider using a soft-bristled toothbrush to clean your aligners daily.
- Soak daily: Soak your aligners daily using one of the recommended cleaners and follow the instructions carefully. Be mindful not to soak them excessively, as prolonged exposure to certain solutions could cause damage.
- Store appropriately: When not in use, always store your aligners in their protective case to avoid exposure to bacteria and prevent loss or damage.
