Are you unsure of how to clear Invisalign trays? If so, you have ended up in the right place, because this brief article is all about how to clean and maintain your Invisalign braces.

Even though every set of aligners is only meant to last you a few weeks before it can be discarded, it is still very important to keep your Invisalign trays clean in the meantime – otherwise, you might quickly find yourself with a whole new set of dental issues that will need to be addressed. And really, what is the point in spending money on the Invisalign treatment and achieving perfectly straight teeth if it means they are going to be riddled with other problems such as dental decay?

As a rule of thumb – and as recommended on the Invisalign website – you should clean your Invisalign trays at least once a day. If you make cleaning your Invisalign set of aligners a part of your evening routine, it becomes easy to remember to actually do it every time. Cleaning your aligners at the same times that you also brush your teeth is a great way of getting in the the habit and putting that habit on autopilot

It is not enough to simply rinse your aligners, and it isn’t enough to soak your aligners overnight either, since both of these approaches will only eliminate obvious food particles while leaving plenty of invisible micro-bacteria to flourish.

Without further ado, let us delve into the best practices for keeping your Invisalign aligners clean and fresh, so that they can work their magic in your mouth without causing any counterproductive damage.

How to clean Invisalign trays

When it comes to keeping your Invisalign aligners clean, it does not have to be complicated.

There is a very simple cleaning method recommended by Invisalign, which should be sufficient to keep your aligners clean and free from food particles and bacteria. However, there is also a slightly more onerous way to clean Invisalign trays which requires a few more steps and a little more effort, but you might still consider it worth it if you want to make absolutely sure that your aligners are as clean, spotless and bacteria free as possible.

Basic cleaning method

The basic cleaning method recommended by Invisalign consists of just a few simple steps.

First, remove your clear aligners from your mouth and rinse them with lukewarm or warm water. Once you have gotten rid of any obvious food particles and other debris, the next step is to gently clean your trays using a soft-bristled toothbrush. Make sure that you are using a clean and purpose-specific toothbrush, and not the same brush that you are also using to brush your teeth with. Instead of toothpaste, you can choose to use a gentle liquid soap – just make sure that you rinse the soap off your aligners properly before putting them back in your mouth!

Now that they have been cleaned, take your aligners and rinse them thoroughly again to get rid of any traces of soap that might be lingering. Finally, if you are not going to be putting your aligners back in your mouth right away, it is best to keep them stored in a protective case until it is time to wear them again.

Advanced cleaning method

If you like to be thorough, here is an alternative method of Invisalign cleaning.

According to a study that was published in the journal ‘Clinical, Cosmetic, and Investigational Dermatology,’ in which three different approaches to cleaning clear aligners were studied side by side, the most effective way of cleaning the aligners was to use effervescent tablets dissolved in water for an extra deep clean. The next most effective method was brushing the aligners using a toothbrush and toothpaste or soap, and the least effective method of the three that were looked at was merely rinsing the aligners with warm water.
