Cleaning Invisalign: Essential Dos and Don’ts for Wearers
Essential dos and don’ts for keeping Invisalign aligners clean, clear, and fresh with easy, friendly advice for everyday care.

Keeping your Invisalign aligners clean is essential for comfort, oral health, and maintaining that crystal-clear look. Many wearers aren’t sure exactly what to do, or worry about damaging them by mistake. The good news is it’s simple with the right approach. This guide offers friendly, down-to-earth advice on what you should and shouldn’t do, so you can confidently care for your aligners and make your Invisalign journey as smooth and successful as possible.
Why It Matters to Clean Your Invisalign Aligners
Your aligners sit against your teeth for most of the day. That’s a lot of time for bacteria, plaque, and food particles to build up. Cleaning isn’t just about keeping them clear and presentable, it's about protecting your teeth and gums too.
If you don’t clean them properly:
- They can become cloudy and stained.
- Bacteria can multiply, causing bad breath.
- Plaque can spread to your teeth, risking decay or gum irritation.
Invisalign aligners are removable, which makes them easier to keep clean than traditional braces but only if you commit to a routine.
Essential Dos for Cleaning Your Aligners
Clean Them Thoroughly Twice a Day
Make cleaning your aligners part of your morning and bedtime routines. When you wake up, they’ll have built up bacteria overnight. Before bed, you’ll remove the day’s plaque and any food particles.
It doesn’t need to be complicated:
- Remove aligners.
- Rinse under lukewarm water.
- Use a soft toothbrush (dedicated for aligners) with gentle, clear soap.
- Brush all surfaces lightly.
- Rinse again until all soap is gone.
This habit keeps them clear, fresh, and free from bacteria.
Rinse Every Time You Remove Them
- Stop residue drying onto the plastic.
- Reduces odour.
- Helps avoid plaque build-up.
Use Gentle Cleaning Solutions
Not all cleaners are safe for Invisalign. Harsh chemicals can damage the plastic or leave residues you don’t want in your mouth.
Safe options include:
- Clear, unscented liquid soap.
- Invisalign cleaning crystals or branded retainer-cleaning tablets.
- Gentle, non-abrasive cleansers designed for dental appliances.
Avoid anything too strong or abrasive to preserve the clarity of your aligners.
Soak Them Regularly
Daily soaking is a great extra step that helps prevent staining and bacteria build-up.
Here’s how:
- Dissolve a cleaning tablet in lukewarm water as instructed.
- Place aligners in the solution for 15–20 minutes.
- Rinse thoroughly with water before putting them back in.
Store Them Properly
When you’re not wearing your aligners, keep them safe in their case.
Don’t:
- Wrap them in a napkin as they can easily be thrown away.
- Leave them out exposed to bacteria.
- Leave them in hot environments like a car.
An Emergency dentist in Bicester often sees patients who’ve accidentally lost or damaged aligners simply because they didn’t use their case. It’s an easy habit to adopt that can save you hassle and cost.
The Don’ts for Cleaning Your Invisalign
Don’t Use Toothpaste
Toothpaste seems like the obvious cleaner but it’s actually too abrasive for aligners.
It can:
- Scratch the plastic.
- Make them appear cloudy.
- Reduce their clarity.
Stick to mild soap or cleaning solutions specifically designed for clear aligners. Your smile will thank you.
Don’t Use Hot Water
Hot water is a definite no for cleaning Invisalign.
Even slightly too hot can:
- Warp the plastic.
- Change the fit.
- Undermine your treatment progress.
Always use lukewarm or cool water when rinsing, soaking, or brushing your aligners.
Don’t Eat or Drink with Aligners In
Invisalign should always be removed for meals or drinks (except plain water).
Food and coloured drinks can:
- Stain the aligners.
- Trap particles against your teeth.
- Increase the risk of decay.
Removing them for meals also makes it easier to maintain good oral hygiene before putting them back in.
Don’t Skip Brushing and Flossing Your Teeth
Your teeth need to be clean before aligners go back in.
Otherwise:
- Plaque and bacteria get trapped against them.
- Risk of cavities or gum irritation rises.
- Bad breath becomes more likely.
How to Handle Stains and Odours
Aligners can pick up stains from:
- Tea and coffee
- Red wine
- Curry or richly coloured sauces
- Smoking
To manage this:
- Always remove them before consuming stain-prone foods or drinks.
- Clean them immediately if you notice discolouration.
- Use cleaning crystals or soaking tablets to tackle stubborn stains.
If you’re worried about persistent staining, your Invisalign Bicester dentist can help check your technique and suggest replacements if necessary.
Travelling with Invisalign
Don’t neglect cleaning just because you’re away from home.
A simple travel kit can help:
- Small soft-bristle toothbrush
- Clear, unscented liquid soap
- Compact aligner case
- Bottle of water for rinsing
Having these essentials on hand makes it easy to stick to your routine even on busy days or holidays.
Troubleshooting Common Invisalign Issues
Cloudy or Scratched Aligners
Usually from:
- Using abrasive toothpaste
- Scrubbing too hard
- Soaking in harsh solutions
To avoid this:
- Stick to gentle cleaners.
- Use a soft toothbrush.
- Follow recommended soaking instructions.
Warped Aligners
Nearly always caused by heat.
Never:
- Rinse in hot water.
- Leave them in direct sun or hot cars.
Lost or Broken Aligners
Accidents happen. If you lose or break an aligner:
- Keep your previous set your dentist may want you to wear temporarily.
- Contact your Invisalign provider immediately.
- Use your case to avoid losing aligners in future.
Maintaining Oral Health with Invisalign
Your aligners won’t cause cavities, but they can trap food and bacteria against your teeth if you don’t maintain good hygiene.
Basic daily routine:
- Brush teeth twice with fluoride toothpaste.
- Floss at least once a day.
- Clean aligners thoroughly.
- Attend regular dental check-ups.
Following these steps helps keep your teeth and aligners clean, protecting your smile throughout treatment.
