How to Clean Your Aligners: A Step-by-Step Guide

Wearing aligners is one of the most convenient and discreet ways to straighten your teeth, but keeping them clean is just as important as wearing them consistently. Since clear aligners are worn for around 20–22 hours a day, they are constantly exposed to saliva, food particles, and bacteria. If not cleaned properly, dental aligners can become discoloured, develop odours, and even affect your oral health.

This step-by-step guide will show you how to clean your aligners correctly, what to avoid, and why a proper cleaning routine is essential for a healthy, confident smile.

Why Cleaning Your Aligners Matters

• Prevents Bacteria Build-up: Clear aligners fit snugly over your teeth, creating an environment where bacteria can thrive. Without proper cleaning, this can lead to plaque build-up, bad breath, and even gum issues.

• Maintains Clarity: One of the main appeals of aligners is that they are nearly invisible. Neglecting cleaning can cause them to look cloudy or stained, reducing their discreet appearance.

• Ensures Effectiveness: Dirty aligners can warp or weaken if cleaned improperly. By caring for them correctly, you protect your investment in a straighter smile.

• Supports Oral Health: Your aligners are in close contact with your teeth. Keeping them clean means you’re less likely to transfer bacteria back into your mouth.

Step-by-Step Guide to Cleaning Your Aligners

Step 1: Rinse Your Aligners Every Time You Remove Them

Each time you take your aligners out, for meals, snacks, or drinks, rinse them under cool running water. This helps wash away saliva and reduces bacteria build-up. Avoid hot water, as it can warp the plastic material.

Step 2: Brush Your Teeth Before Reinserting

Before putting your aligners back in, always brush and floss your teeth. If you skip this step, trapped food particles can stain your aligners and increase the risk of cavities.

Step 3: Use a Soft-Bristled Toothbrush for Cleaning

Gently brush your aligners with a soft-bristled toothbrush and mild, clear antibacterial soap. Avoid whitening toothpaste, as it can scratch the aligner surface and cause discoloration.

Step 4: Soak Your Aligners Daily

To keep them fresh and odour-free, soak your aligners in a cleaning solution once a day. You can use a retainer cleaning solution, or a gentle homemade mix of equal parts water and white vinegar. After soaking, rinse thoroughly with cool water before wearing.

Step 5: Avoid Staining Foods and Drinks

Coloured drinks such as coffee, tea, or red wine can stain aligners if worn while drinking. Always remove your aligners before consuming anything besides water.

Step 6: Store Them Safely When Not in Use

Whenever you remove your dental aligners, store them in their protective case. Leaving them exposed increases the risk of bacteria contamination and accidental damage.

Common Mistakes to Avoid When Cleaning Aligners

• Using Hot Water: Heat can change the shape of your aligners, making them less effective. Always use cold or lukewarm water. 

• Scrubbing Too Hard: Brushing with force or using abrasive toothpaste can cause scratches that make aligners more noticeable.

• Skipping Daily Cleaning: Even if your aligners look clean, bacteria are invisible. A daily cleaning routine is essential.

• Leaving Aligners Out in the Open: Exposure to air and surfaces can invite harmful bacteria. Always keep them in a case when not wearing them.

How Often Should You Clean Your Aligners?

• Rinse: Every time you remove them.

• Brush: At least twice a day.

• Soak: Once daily.

Maintaining this schedule will ensure your clear aligners remain transparent, hygienic, and effective.

Aligners vs. Traditional Braces: Cleaning Made Easier

One of the biggest advantages of clear aligners is how much easier they are to clean compared to metal braces. With braces, food often gets trapped around wires and brackets, requiring special brushes and flossing tools. Aligners, on the other hand, are removable, which makes everyday cleaning simpler and helps you maintain better oral hygiene throughout treatment.
