You love how your Invisalign® aligners are discreetly straightening your teeth, a journey you may have started with the team at Markham Dental. But it probably didn’t take you long to realize that after a few hours of wear, they can start to feel a little fuzzy or develop a slight odour, taking away from that clean-mouth feeling everyone enjoys.
Keeping your aligners in great shape is simpler than you might think. A combination of daily cleaning and a regular deeper disinfection routine can help keep your Invisalign® trays clear, fresh, and comfortable throughout your treatment.
Why You Need to Disinfect Your Aligners
Prevent Buildup & Odour
Just like your teeth, your aligners can accumulate bacteria and plaque. This buildup can lead to unpleasant smells and make the plastic feel slick or fuzzy. A consistent cleaning routine helps manage bacteria and keeps your breath feeling fresh.
Keep Your Aligners Clear & Invisible
One of the main appeals of Invisalign® is that the aligners are hard for other people to see. However, food particles and drinks like coffee or red wine can stain the plastic, making it look yellow or cloudy. Proper disinfection helps your aligners stay transparent so your smile is what people notice.
Simple Daily Disinfection Methods
Rinse Your Aligners After Removal
Every time you take out your aligners to eat or drink, give them a quick rinse. Use cool or lukewarm water (never hot) to wash away saliva and any loose food particles. This simple step helps prevent buildup from drying onto the surface.
Brush Aligners Gently
You can also gently brush your aligners each day. Use a separate, soft-bristled toothbrush and a small amount of clear, unscented soap. Carefully brush all the surfaces, inside and out, then rinse them thoroughly before putting them back in your mouth.

Deeper Disinfection for a Thorough Clean
Use At-Home Solutions
For a more thorough clean, you can soak your aligners in a simple homemade solution. A mix of equal parts white vinegar and water works well, or a solution of 1 part hydrogen peroxide to 2 parts water can help disinfect them. Another option is a paste made from baking soda and water, which you can use to gently scrub the aligners.
Try Commercial Cleaning Products
If you prefer a ready-made option, you can find products designed for this purpose. Denture or retainer cleaning tablets work well for a deep soak. When choosing a product, you can look for those that have earned the CDA Seal of Recognition. You can also find cleaning crystals made specifically for Invisalign® that dissolve in water to create an effective disinfecting bath.
What to Avoid When You Disinfect Aligners
Protecting your aligners is key to reaching your cosmetic dentistry goals. When you clean them, there are a few things you should try to steer clear of to prevent damage. Make sure to avoid:
- Hot water: High temperatures can warp the plastic, changing the shape of your aligners and affecting your treatment progress.
- Harsh chemicals: Bleach, alcohol, and harsh soaps can damage the aligner material and are unsafe to put in your mouth.
- Abrasive toothpaste: Many kinds of toothpaste (especially whitening formulas) contain rough, scratchy ingredients that can dull your aligners.
