A Practical Guide on How Often to Clean Invisalign

Did you know that clear orthodontic aligners, like Invisalign, can lead to the development of oral biofilms, potentially causing dental caries, periodontal disease, and even systemic infections? That’s why it’s important to regularly clean and disinfect your aligners to keep your mouth healthy and avoid problems. 

If you’re undergoing or considering this treatment, this guide will answer the common question, “How often should I clean Invisalign?” We’ll break down the ideal cleaning schedule, recommend the best cleaning methods, and share tips to prevent bacteria buildup.

What Is Invisalign?

Invisalign aligners, made from clear, flexible plastic like SmartTrack material, are designed to discreetly and effectively straighten teeth. They are a popular alternative to traditional braces due to their aesthetic appeal and convenience. Being removable, they allow for easy cleaning and enable you to eat without food restrictions.

Why Clean Them Regularly?

Regular cleaning of Invisalign aligners is essential to:

  • Prevent bacterial buildup and reduce the risk of oral infections.
  • Minimize plaque buildup to avoid cavities and gum disease.
  • Remove trapped food particles, preventing bad breath and staining.
  • Maintain the aligner’s transparency for a clear and invisible appearance.
  • Ensure proper fit and effectiveness in moving teeth to the desired position.
  • Support overall oral hygiene to protect against dental issues related to misalignment.

How Often Should You Clean Your Invisalign?

So, how often should you clean Invisalign? 

At a minimum, you should give them a thorough cleaning once a day, ideally before bed. This helps remove bacteria, plaque, and any food particles that build up throughout the day.

It’s also smart to rinse your aligners with lukewarm water every time you take them out, especially after eating or drinking anything besides water. If possible, give them a quick brush or clean before putting them back in to keep them fresh and hygienic.

How to Clean Your Invisalign

Here’s a comprehensive guide utilizing various cleaning techniques and products to ensure your aligners remain pristine and hygienic.

Daily Cleaning Routine

Inspect for Damage

To prevent treatment delays, regularly inspect your aligner trays for cracks or damage. If you notice any issues, consult your orthodontist to discuss possible replacements.

Rinse Upon Removal

Every time you remove your aligners, rinse them with lukewarm water to wash away saliva and reduce plaque buildup. Avoid using hot water, as extreme temperatures can warp the plastic material and compromise the fit.

Brush Your Aligners

Use a soft-bristled toothbrush or a baby toothbrush to gently brush your aligners with clear, unscented antibacterial soap or mild liquid soap. This process effectively removes food particles and buildup. Make sure to rinse with clean water to get rid of any soap residue before reinserting your aligners. Harsh, abrasive materials can scratch the aligner surfaces, making them more susceptible to bacteria buildup.

Soak Daily

Incorporate a daily soak in a cleaning solution like cleaning crystals or a homemade mixture of one part vinegar to three parts warm water. Allow your aligners to soak for about 15-20 minutes for optimal results. Rinse thoroughly with clean water afterward.

Dry Properly Before Storage

After cleaning, shake off excess water and gently pat the trays dry with a clean towel. Always store them in their case to protect against damage and loss.

Clean After Eating

In addition to the daily routine, brush your teeth and clean your aligners after each meal to prevent food particles from becoming trapped between your teeth and the aligners. If you don’t have enough time, just rinse your aligners with water.

Weekly Deep Cleaning

In addition to daily maintenance, a more thorough cleaning process should be conducted weekly. This helps in breaking down any plaque build-up or bacteria build-up that may have accumulated over time.

Use a Specialized Cleaning Product

Once a week, perform a deep clean using specialized products like effervescent tablets, denture cleaners or retainer tablets. Follow the manufacturer’s instructions for best results, ensuring every corner of the trays is thoroughly cleaned.

Use Baking Soda Paste

If you prefer a DIY approach, a paste made from baking soda and water can serve as an effective alternative. For an extra clean, sprinkle a small amount of baking soda onto your plastic trays and gently scrub them with a soft toothbrush. Baking soda’s mildly abrasive properties help dislodge stubborn residue without damaging the plastic. Rinse well when finished.

Use Hydrogen Peroxide Soak

Consider soaking your aligners in a solution of equal parts water and hydrogen peroxide once a week. Let them soak for about 30 minutes to kill bacteria and slightly whiten the aligners. Ensure you rinse them well before wearing them.

Use an Ultrasonic Cleaner

If possible, use an ultrasonic cleaner. This device uses sound waves to remove debris from your trays, reaching even the smallest crevices for a thorough clean. Adhere to the manufacturer’s guidelines for use.

Additional Tips


✓ Always store your aligners in the protective case when not in use to prevent damage or loss.

✓ Brush your teeth before putting aligners back in to avoid trapping food particles and plaque.

✓ A quick rinse with a suitable mouthwash can help maintain oral hygiene without affecting your aligners.

✓ Keep extra cleaning supplies, like a soft toothbrush and mild soap, handy in case your regular items run out.

✓ Make it a habit to clean your aligners after meals to prevent food particles from lingering on them.

Invisalign Care While Traveling

It’s easy to fall out of routine while traveling, but your aligners still need daily care. Here’s how to stay on track:

  • Pack a Travel Cleaning Kit: Include a soft toothbrush, mild soap, a retainer case, and travel-size mouthwash.

  • Keep Your Aligners in a Case: Never wrap them in a napkin or leave them out—they can easily be lost or damaged.

  • Stick to Your Cleaning Schedule: Even during a hectic day, make time for your rinse-and-brush routine.

  • Bring a Backup Tray (if available): In case you misplace one, having a spare aligner from your previous set can help prevent treatment delays.

With just a little prep, you can maintain your Invisalign hygiene from anywhere.

Signs Your Aligners Need More Attention

If you notice any of the following issues, it may be time to enhance your cleaning routine:

  • Discoloration: If your aligners have become noticeably cloudy or yellowed, they may need a more intensive cleaning routine.
  • Odor: An unpleasant smell from your aligners can signal the buildup of bacteria and necessitates immediate attention.
  • Visible Residue: If you can see any deposits or plaque on your aligners that brushing and soaking don’t remove, it’s time to switch up your cleaning method.
