Your Invisalign aligners work hard to straighten your teeth and eliminate tooth gaps, but they require proper care to stay clear, hygienic, and effective throughout your treatment. Several ways to effectively clean your Invisalign aligners include:
- Rinsing your aligners regularly
- Using a soft-bristled toothbrush
- Using Invisalign cleaning crystals
- Using a retainer cleaning solution
Poor aligner hygiene can lead to bacterial buildup, tooth decay, and even treatment delays. But the good news is that with the right approach, keeping your aligners spotless is easier than you might think. Discuss Invisalign care with your dentist if you’re having trouble with aligner hygiene.
What Is Invisalign?
Invisalign uses a series of custom-made, clear plastic aligners to move your teeth into their desired positions gradually. Unlike traditional braces with metal brackets and wires, these virtually invisible aligners are removable, making them a popular choice for adults and teens who want to discreetly straighten their teeth.
Innovative computer-imaging technology, like the iTero 3D, is used to create your comprehensive treatment plan, providing a clear visual representation of how your teeth will move from start to finish.
Cleaning Your Invisalign: Why It Matters
When you don’t clean your Invisalign aligners regularly, several problems can develop that affect both your oral health and treatment success.
Bacterian & Plaque
Bacteria and plaque accumulate on your aligners just like they do on your teeth. Without regular cleaning, this buildup creates an ideal environment for harmful microorganisms to thrive. The warm, moist conditions inside your mouth can accelerate bacterial growth, leading to bad breath, tooth decay, and gum disease.
Staining & Discolouration
Staining is another common issue with poorly maintained aligners. Coffee, tea, wine, and even certain foods can discolour your aligners, making them visible and defeating the purpose of “invisible” orthodontic treatment. Cloudy or yellowed aligners are often the first sign that your cleaning routine needs improvement.
Improper Fit
Perhaps most importantly, dirty aligners can interfere with your treatment progress. Bacteria and plaque buildup can prevent your aligners from fitting correctly, which may slow down tooth movement or require additional treatment time.
How Often Should You Clean Your Invisalign?
Establishing a consistent cleaning schedule is crucial for maintaining healthy, clear aligners throughout your treatment.
Daily Cleaning
Clean your aligners every morning and evening as part of your regular oral hygiene routine. This twice-daily cleaning removes the bacteria and plaque that accumulate during normal wear. Morning cleaning is crucial because bacteria can multiply overnight.
After Meals
While you should remove your aligners before eating or drinking anything other than water, it’s essential to clean both your teeth and aligners before reinserting them. Food particles and sugars left on your teeth can get trapped under your aligners, creating an environment where bacteria thrive.
Deep Cleaning 2–3 Times Per Week
Beyond daily maintenance, your aligners need more thorough cleaning several times per week. Deep cleaning removes stubborn buildup that regular rinsing can’t eliminate and helps prevent odours and staining from developing.
Effective Invisalign Cleaning Methods
Several cleaning methods can help keep your aligners clear and hygienic. The key is to find techniques that work with your lifestyle and budget, while providing thorough cleaning without damaging the plastic.
Rinse with Lukewarm Water
The most straightforward and most crucial cleaning step is rinsing your aligners with lukewarm water every time you remove them. This prevents saliva, bacteria, and food particles from hardening on the surface.
Use lukewarm rather than hot water, as high temperatures can warp the plastic and affect the fit of your aligners. Cold water is less effective at removing bacteria and buildup. Lukewarm water strikes the right balance, cleaning effectively without risking damage.
Invisalign Cleaning System
The official Invisalign cleaning system uses specially formulated crystals that dissolve in water to create a cleaning solution. This system is designed specifically for Invisalign aligners and won’t damage the plastic or affect the fit.
To use the cleaning crystals, dissolve one packet in lukewarm water and soak your aligners for 15 minutes. The solution removes plaque and bacteria while keeping the aligners clear and odour-free. After soaking, brush the aligners gently with a soft toothbrush and rinse thoroughly.
A Soft-bristled Toothbrush
Gentle brushing with a soft-bristled toothbrush helps remove plaque and bacteria that rinsing alone can’t eliminate. Use a separate toothbrush dedicated to cleaning your aligners to prevent transferring bacteria from your teeth to your aligners.
Avoid toothpaste when brushing your aligners, as many toothpastes contain abrasive ingredients that can scratch the plastic surface. These tiny scratches make aligners appear cloudy and provide hiding spots for bacteria. Instead, use plain water or a mild, clear liquid soap.
Retainer Cleaning Tablets
Denture and retainer cleaning tablets offer an affordable alternative to the official Invisalign cleaning system. These effervescent tablets dissolve in water to create a cleaning solution that removes bacteria, plaque, and odours.
Soak your aligners according to the manufacturer’s instructions, which typically range from 15–30 minutes. After soaking, brush gently with a soft toothbrush and rinse thoroughly before reinserting.
