How to Clean Invisalign Aligners: Basic Tips and Tricks

Updated: Oct 4

Invisalign aligners are a fantastic option for straightening your teeth without the hassle of traditional braces, but keeping them clean is vital to ensuring they stay clear and effective.


Proper cleaning helps your aligners look good and protects your oral health by reducing bacteria and preventing stains.


Next, we’ll walk you through how to clean Invisalign aligners and share tips and tricks for keeping them in top shape. 


Why Cleaning Invisalign Aligners is Important

Keeping your Invisalign aligners clean is essential for maintaining their appearance and protecting your oral health.


Here's why it's important:


Preventing Discoloration


Cleaning your Invisalign trays is a must to keep your aligners clear. If you don't clean your aligners often, they can start to look cloudy or even turn yellow. This happens when foods, drinks, or habits like smoking cause stains.


Cigarettes are a major contributor to discoloration. The tar and nicotine in tobacco can lead to nasty smells and stubborn stains on both your teeth and aligners. Smoking not only increases the risk of yellowing your Invisalign trays but can also worsen gum disease, inflammation, and tooth loss over time. 


It's important to clean your aligners thoroughly, as the chemicals from tobacco use can become trapped in the trays, exacerbating oral health issues and making bad smells harder to eliminate.


Common culprits like coffee, tea, wine, and soda can also stain your aligners. To prevent this, clean your aligners after eating or drinking anything besides water. 


Soaking your aligners in an Invisalign cleaning solution can help remove stubborn stains from tar and nicotine as well as food and drink residue.


Reducing Bacteria Buildup


Throughout the day, food particles and saliva get trapped inside the plastic aligners.

This sets up the perfect conditions for bacterial growth. If left unchecked, it could lead to problems like bad breath, gum disease, or even tooth decay.


To avoid these issues, make it part of your daily routine to clean the aligners thoroughly.

You can also use Invisalign cleaning crystals to give them a deeper clean or denture cleaners for a cost-effective option.


Maintaining Hygiene and Oral Health


Plaque can build up on your clear aligners, just like on teeth. If you don’t clean them properly, that plaque can transfer to your teeth and cause cavities or other infections.

Using a soft toothbrush to gently scrub the aligners with lukewarm water or a little clear liquid soap can keep them free from plaque and bacteria.


Before putting your aligners back in, make sure that you’re consistent with your oral hygiene routine, brushing and flossing after every meal.


How to Clean Invisalign Aligners Properly?


A daily cleaning routine for your Invisalign trays is important to prevent bacteria buildup, stains, and unpleasant odors.


Here's the routine you should keep during your treatment:


Rinsing Aligners


One of the easiest ways to keep your Invisalign trays clean is by rinsing them whenever you take them out.


Rinsing helps wash away food particles and prevent bacteria from forming on the aligners. Always use lukewarm water when rinsing.


Avoid hot water, which can warp the clear aligners, making them less effective.


Brushing Aligners


To keep your aligners clean, gently brush them with a soft-bristled toothbrush. 

Avoid using regular toothpaste, especially abrasive ones, since this can scratch the surface of the Invisalign trays, making them look cloudy. 


When brushing, use a soft toothbrush with lukewarm water or a mild cleaning solution like clear liquid soap. 


Brush gently in circular motions to remove plaque without damaging the plastic.


Soaking Aligners


In addition to daily rinsing and brushing, soaking your Invisalign aligners helps give them a deeper clean.


Soak your aligners for 15-20 minutes once a day or as needed using Invisalign cleaning crystals or a gentle denture cleaner.


After soaking, rinse your aligners thoroughly with lukewarm water before putting them back in. This removes any remaining cleaning solution or residue from the cleaning crystals.


How To Clean Invisalign Aligners With Specialized Products?


Specialized products are designed to thoroughly clean your Invisalign trays.

These products are made specifically for Invisalign clear aligners. They help remove food particles, stains, and bacteria, ensuring good oral hygiene throughout treatment.


These are the most popular specialized products for cleaning Invisalign:


Invisalign Cleaning Crystals


One of the best products to keep your Invisalign trays clean is Invisalign cleaning crystals.


These crystals remove hard buildup like plaque and tartar from your clear aligners.

They help keep your aligners clear and free from stains, ensuring they work effectively during your Invisalign treatment.


To use the crystals, dissolve a packet in a cup of lukewarm water, soak your aligners for 15-20 minutes, and rinse thoroughly.


Using cleaning crystals regularly is a simple and convenient way to maintain good oral hygiene.


Invisalign Cleaning Foam


Another product designed for Invisalign clear aligners is Invisalign cleaning foam.

This foam works not only to clean your aligners but also to freshen your breath at the same time.


It’s easy to use: apply the foam directly into your aligners before putting them back in your mouth. The foam helps remove food particles and plaque while you wear your aligners.


For best results, use it once a day to keep your aligners clean and your mouth feeling fresh.


Deep Cleaning Methods for Invisalign Aligners


While daily cleaning keeps your Invisalign trays fresh, sometimes you need a more thorough approach to remove hard buildup and stains.


Deep cleaning methods help keep your aligners in top condition, preventing bacteria and plaque from affecting the aligners and your teeth.


Vinegar and Water Solution


If you’re looking for a natural way to clean your aligners, a vinegar and water solution is a great option.


Mix distilled white vinegar and warm water in a 1:3 ratio and soak your Invisalign trays in the solution for 15-30 minutes.


After soaking, rinse thoroughly with lukewarm water to remove any vinegar taste.


Baking Soda and Water Paste


Another effective cleaning method involves using baking soda.


To make a paste, mix a small amount of sodium bicarbonate (baking soda) with lukewarm water until it reaches a thick, paste-like consistency.


You can use this paste to gently brush the aligners or soak them in the mixture for about 20 minutes. Baking soda helps remove stains and neutralizes odors, keeping your aligners fresh.


Hydrogen Peroxide Solution


For a deeper clean, a hydrogen peroxide solution can be very effective.


Mix equal parts of hydrogen peroxide and lukewarm water, then soak your aligners in this solution for about 30 minutes.


Hydrogen peroxide acts as a natural antiseptic, killing bacteria and helping to prevent stains.


Make sure to rinse your aligners thoroughly with lukewarm water after soaking to remove any leftover solution.


Common Mistakes to Avoid


When you first start using Invisalign, it's easy to make a few common cleaning errors that could harm your aligners or interfere with your treatment. 


Avoiding these mistakes right away will help your aligners to maintain in the best possible condition and to make sure your progress continues as planned. 


Here are some things to be aware of:


Using Harsh Chemicals or Toothpaste


Many people think cleaning their aligners with regular toothpaste or soap is a good idea, but these products can damage the trays.


Toothpaste, especially the abrasive kind, can scratch the surface of the Invisalign trays, making them look cloudy. Harsh chemicals like bleach or strong soap can weaken the plastic.


Instead, stick to gentle cleansers like clear liquid soap, lukewarm water, or specialized products like Invisalign cleaning crystals or denture cleaners.


Eating or Drinking with Aligners On


It can be tempting to leave your aligners in while eating or drinking, but this is one of the biggest mistakes to avoid.


Food and drinks, especially sugary ones, can stain your clear aligners or cause bacteria to grow, leading to bad breath and tooth decay.


Always remove your aligners before eating or drinking anything other than water to protect your aligners.


Not Cleaning the Case


A common oversight is forgetting to clean the case where you store your Invisalign aligners.


If not cleaned regularly, the case can quickly become a breeding ground for bacteria. To keep it hygienic, rinse the case daily with warm water and let it air dry.


You can clean it more thoroughly with clear liquid soap or a mild disinfectant like rubbing alcohol once a week.


Infrequent Cleaning of Aligners


Skipping daily cleaning can lead to unpleasant odors and a buildup of bacteria on your aligners.


It’s essential to clean your aligners daily, especially after meals, to prevent bacteria and plaque from transferring to your teeth.


A simple rinse or brushing with a soft-bristled toothbrush is usually enough to keep your Invisalign clean and fresh.


Storing Aligners Unprotected


Leaving your aligners out of their case when not in use is another mistake that can lead to problems.


When left unprotected, your aligners can easily get lost, damaged, or exposed to bacteria.


Always store your Invisalign trays in their case to keep them safe and clean when not in your mouth. This also helps reduce the risk of bacteria buildup.





Additional Tips for Maintaining Invisalign Aligners


Along with the cleaning tips we shared, there are some extra tips you could follow to maintain your Invisalign aligners in excellent condition:


Keeping Aligners in a Safe Place


It's easy to lose or damage your Invisalign aligners if you don’t store them properly.

Always use the protective case that came with your orthodontic treatment. When you remove your aligners to eat or drink, immediately put them in the case.


You can prevent your aligners from getting misplaced, broken, or contaminated by doing this. Developing a usage habit for the case will guarantee their longevity and safety.


Regular Visits to the Dentist


While cleaning your aligners daily is essential, regular visits to your dentist are just as important.


Your provider can check for discoloration, plaque buildup, or damage that might not be visible.


Professional cleanings and regular checkups help ensure your Invisalign treatment stays on track. If you notice any issues, like cracks or hard buildup, bring them up during your appointment.


Avoiding Exposure to Extreme Temperatures


Heat and cold can easily warp your Invisalign trays.


For example, rinsing your aligners in hot water or leaving them in a hot car can cause them to bend or lose shape.


Always use lukewarm water when cleaning them, and avoid leaving your aligners in places with high heat or extreme cold. Proper care ensures your clear aligners stay effective and fit correctly.


Monitor for Wear and Tear


Over time, your invisible aligners might show signs of wear, like small cracks or rough edges.


It’s a good idea to inspect your aligners daily for damage. If you notice a crack or significant wear, contact your dentist for a replacement.


Using damaged aligners could slow down your Invisalign treatment or cause discomfort.


Traveling with Aligners


When you’re on the go, it’s essential to maintain your oral hygiene and keep your aligners clean.


Carry a small, portable cleaning kit with a soft toothbrush, lukewarm water, and possibly some Invisalign cleaning crystals.


Having these essentials on hand makes it easier to clean your Invisalign trays while traveling. Ensure you also bring your protective case to avoid losing your aligners while away from home.


Conclusion


As you can see, keeping your Invisalign aligners clean is essential for both your oral health and the longevity of the aligners.


You can ensure they stay fresh and clear with a few simple habits and occasional deep cleaning.
