How to Clean Invisalign Aligners: Dos and Don’ts for Tray Cleaning

Understanding Invisalign Aligners: The Key to a Beautiful Smile

Invisalign aligners, those discreet and transparent orthodontic retainers designed to gently shift your teeth into precise positions, have become the favored choice for individuals seeking to rectify dental issues such as overbites, crossbites, and ultimately, enhance their smile. Given that these aligners are worn diligently for an impressive 20 to 22 hours daily, maintaining their cleanliness becomes paramount. Indeed, aligner cleaning is an integral aspect of your Invisalign regimen.

Invisalign Cleaning Tips

What Constitutes Invisalign Aligners?

Invisalign aligners are, in essence, clear and virtually invisible retainers that you wear for a substantial portion of your day to achieve optimal results. Given our daily habits of eating, drinking, and snacking, it is prudent to acquaint yourself with various methods for effectively cleaning Invisalign Aligners.

Engaging in orthodontic treatments, such as Invisalign or traditional braces, often marks the pursuit of a more captivating smile. As individuals embark on these orthodontic journeys, they invariably become more conscious and attentive to the importance of maintaining pristine dental health.

Our understanding of proper dental hygiene begins in our formative years. Recognizing that the mouth, teeth, and gums are breeding grounds for harmful bacteria, which can lead to issues like bad breath and tooth decay, we have consistently sought out the best practices for maintaining oral health. This includes selecting the softest toothbrush, identifying the ideal toothpaste for specific dental concerns, devising personalized cleaning routines, and nurturing a commitment to oral hygiene.

Much like our meticulous care for our teeth and our unceasing quest for the most effective methods to preserve clean and healthy oral cavities, we must extend the same level of care to our orthodontic instruments, including Invisalign aligner trays. Just as we conscientiously schedule regular dental cleanings, typically biannually, to eliminate plaque buildup, we must also adopt appropriate measures to ensure the cleanliness and sanitization of our Invisalign retainers. This diligence in maintaining clean aligners undoubtedly contributes to overall dental well-being.

How to Clean Invisalign Aligners Effectively


1. Employ the Official Invisalign Cleaning System

When it comes to cleaning your Invisalign aligners, the first and recommended option is to utilize the official Invisalign cleaning system. Upon embarking on your Invisalign journey, you receive a black box containing specialized cleaning crystals. To employ this method, follow these steps:

  • Dissolve the Invisalign cleaning crystals in lukewarm water.
  • Submerge clear aligners in this solution for approximately 15 minutes.
  • After the soaking period, remove the aligners, rinse them thoroughly with water, and place them back onto your teeth.

Notably, these cleaning crystals are readily available for purchase from various sources, including popular online platforms like Amazon.

2. Crafting Your Own DIY Tray Cleaning Solution

If you prefer a more DIY approach, there are six alternative cleaning solutions to have aligners clean that you can prepare at home:

1) White Vinegar: Create a mixture consisting of 1 part white vinegar and 3 parts water. Soak your aligners in this distilled white vinegar solution for 15 minutes, then inspect for any residual food stains, which can be gently removed with an ultra-soft toothbrush.

2) Baking Soda: Add a spoonful of baking soda to a cup of warm water. Allow your aligners to soak in this solution for 15-30 minutes, and subsequently, check if any additional brushing is necessary.

3) Liquid Soap: Opt for a clear, gentle liquid soap to clean your aligners. After cleaning, ensure thorough rinsing to prevent any lingering aftertaste upon reinsertion.

4) Hydrogen Peroxide: Mixing hydrogen peroxide with water (in a 1:1 ratio) provides an effective cleaning solution. Soak your Invisalign aligners for about 30 minutes, followed by rinsing and gentle brushing with a soft toothbrush.

5) Mild Toothpaste and Soft Bristled Toothbrush: Any toothpaste you currently use can serve as an efficient cleaning alternative for your aligners. Implement a gentle brushing routine and rinse with warm water for optimal results.

6) Warm Water: A simple rinse with warm water can suffice. If required, you can apply unscented, uncolored soap directly to the aligners, ensuring thorough rinsing. This option is especially suitable for those with sensitive teeth.

3. Utilize a Protective Case for Your Aligners

While you may feel confident in your ability to keep track of your aligners, unforeseen circumstances can occur. Some patients have inadvertently left their aligners wrapped in paper towels at restaurants, only for staff to mistake them for trash. Retrieving misplaced aligners is a challenging endeavor. Therefore, the most effective practice for preserving your aligners is to store them in their protective case whenever they are not in use.

4. Stay Hydrated with Water

If you change to a new set of Invisalign aligners weekly, maintaining proper care of both your teeth and trays remains essential. As you embark on your Invisalign journey, you may notice increased dryness in your mouth. Combat this by prioritizing water consumption over sugary drinks, ensuring your mouth remains in optimal condition throughout the treatment process.

Keep Your Aligners and Mouth Clean


1. Caution When Cleaning Aligners:

When caring for your Invisalign aligners, there are specific substances and practices to steer clear of:

1) Strongly Scented Hand Soaps

Hand soaps come in an array of colors, scents, and textures. While you enjoy the freedom to select your preferred hand soap, strongly scented varieties with vibrant colors are less suitable for cleaning your aligners and retainers. These can potentially leave visible stains and an aftertaste that may linger when wearing the aligners again.

2) Colored Mouthwash

Some mouthwash products incorporate colored ingredients, which can occasionally stain both your teeth and invisible aligners. It’s important to avoid any mouthwash containing chemical color dyes. Regularly inspect the ingredient list if you are a frequent user of mouthwash.

3) Hot Water

Steer clear of using hot water to rinse your aligners, as it has the potential to alter their shape. Invisalign aligners are designed to remain soft and maintain their original form. Instead, opt for lukewarm water when washing and rinsing your aligners.

4) Vigorous Brushing with a Firm Toothbrush

Invisalign’s primary benefit is its near-invisibility. To retain this feature, avoid using a firm toothbrush for cleaning your aligners, as it can cause scratches that render them more visible when worn. Opt for the gentlest toothbrush you can find if you need to brush them.

2. Remove Invisalign Aligners When Eating

Prevent discoloration of your aligners by removing them when consuming beverages like tea, coffee, or foods with strong pigments such as turmeric. Failing to remove your aligners during meals can also affect your teeth’s health, as food debris may accumulate within the aligners and between your teeth. To mitigate this, always remove your aligners before eating, and remember to brush and floss before reinserting them.

3. Limit Your Beverage Choices to Water

While wearing your aligners, restrict your beverage consumption to water only. Other beverages can lead to an unpleasant taste over time and rapid discoloration of the invisible aligners. An example is provided: even a single cup of Earl Grey tea caused slight discoloration to light golden beige within a few hours. However appealing the new hue may be, remember that your aligners are intended to remain clean, clear, and virtually undetectable, not stained or visible.

4. Safeguard Your Aligners Against Contaminated Surfaces

Minimize the risk of losing or contaminating your aligners by storing them in a clean case rather than leaving them exposed on surfaces. Even if a surface appears clean, it may not be entirely free of contaminants. After meticulously sanitizing your aligners, store them in a secure and hygienic location to avoid unexpected emergencies.
