How to Clean Invisalign Retainer: Easy Step-by-Step Guide
Keeping your Invisalign retainers clean is just as important as wearing them consistently. These clear aligners are designed to be discreet, but without proper care they can become cloudy, stained or even develop unpleasant odours. Worse still, bacteria can build up on the surface and affect your oral health. The good news is that cleaning them doesn’t have to be complicated. With the right habits and a few simple tools, you can keep your Invisalign trays looking fresh and working effectively.
In this guide we’ll walk you through why cleaning is so important, the best step-by-step cleaning method, and some handy do’s and don’ts to keep your aligners in top condition.
Why Cleaning Invisalign Retainers Matters
Invisalign aligners are custom-made to fit snugly over your teeth, which means they’re in constant contact with your mouth, and over time, food particles, plaque and bacteria can accumulate inside them, leading to problems. Listed below are some such issues that can occur with improper cleaning.
- Bad breath caused by trapped bacteria and food debris
- Cloudy, stained aligners that take away from their “invisible” look
- Higher risk of tooth decay and gum problems if bacteria multiply
- Unpleasant taste or odour every time you wear them
By cleaning your Invisalign retainers regularly, you’re not only keeping them clear and comfortable but also protecting your smile throughout treatment.
The Step-by-Step Guide to Cleaning Invisalign Retainers
Here’s a straightforward cleaning routine you can follow every day:
Step 1: Remove Your Retainers Safely
Always wash your hands thoroughly before taking out your aligners. This prevents transferring bacteria or dirt from your hands into your mouth or onto the trays.
Step 2: Rinse with Lukewarm Water
Immediately rinse your retainers under lukewarm water after removing them. This helps wash away saliva and prevents buildup. Avoid hot water, as it can warp the plastic and ruin the fit.
Step 3: Brush Gently
Use a soft-bristled toothbrush (not the same one you use for your teeth) and a small amount of clear, unscented antibacterial soap or Invisalign cleaning crystals. Gently brush all surfaces of the aligners, taking care not to scrub too hard, which can scratch the plastic.
Tip: Avoid toothpaste, as many formulas are abrasive and can leave micro-scratches that make the retainers more prone to staining.
Step 4: Soak Them for a Deep Clean
For a deeper clean, soak your retainers once a day or every other day. Options include:
- Invisalign Cleaning Crystals – specifically designed for aligners, dissolving plaque and bacteria effectively.
- Denture or Retainer Cleaning Tablets – these are widely available and easy to use.
- Mild Antibacterial Soap and Water – for a quick, budget-friendly option.
Let your retainers soak for about 15-20 minutes, then rinse them thoroughly before putting them back in.
Step 5: Rinse Again Before Wearing
After cleaning or soaking, rinse your retainers under lukewarm water to remove any soap or cleaning solution. Then, place them back in your mouth or in their protective case if you’re not wearing them.
Daily Habits to Keep Your Invisalign Clean
Cleaning isn’t just about brushing and soaking. Your everyday habits also play a big role in keeping your aligners fresh.
- Brush and floss your teeth before wearing your aligners. This keeps food particles from getting trapped inside.
- Always store your aligners in their case. Leaving them out in the open exposes them to bacteria and increases the chance of losing them.
- Avoid eating or drinking anything besides water while wearing them. Coffee, tea, wine and even some juices can stain the trays.
- Clean your case regularly. A dirty case can transfer bacteria back onto your clean aligners.
What NOT to Do When Cleaning Invisalign
To make sure your aligners last and stay effective, here are four things to avoid.
- Don’t use toothpaste. It’s too abrasive and can scratch the plastic.
- Don’t use hot water. It can warp and distort the aligners.
- Don’t use coloured or scented soaps. They may stain or leave an unpleasant taste.
- Don’t forget to clean them daily. Skipping cleanings can quickly lead to cloudy, smelly trays.
FAQs About Cleaning Invisalign Retainers
How Often Should You Clean Invisalign Retainers?
Ideally, you should clean your retainers every time you brush your teeth, which is at least twice a day. Rinse them every time you remove them, and give them a deeper soak once daily or every other day. This keeps bacteria under control and prevents odours from developing.
Can I use vinegar to clean my retainers?
Yes, a diluted vinegar solution (half vinegar, half water) can help remove odours and buildup. Just don’t soak them for too long, and rinse thoroughly afterwards.
What if my retainers become stained?
If your retainers are stained despite regular cleaning, it may be time for a professional clean. Bring them to your dentist for advice.
How do I clean my retainers while travelling?
Pack a travel toothbrush, a small bottle of clear soap, and your case. You can also carry cleaning tablets for convenience.
