According to Invisalign, Vivera retainers and Invisalign aligners are considered class “IIa” medical devices. According to the Medical Device Directive 93/42/EEC, they are CE-marked.

Your used aligners must be discarded ethically and handled like medical waste.

2. Your Dentist Can Recycle the Invisalign

Your Invisalign cases, flexible plastic packing, and packaging are collected, cleaned, and then transformed into hard plastic. Then, this is remolded to create brand-new recycled goods.

A variety of plastics are combined to create the multi-layered polymer (Invisalign). As your grin aligns, Invisalign permits both rigidity and suppleness during tooth movement.

Unfortunately, the standard household recycling techniques won’t work because there are separate recycling methods needed for each type of plastic used in Invisalign.

The fantastic news is that your dentist’s office can recycle your Invisalign. Any brand of dental aligners, their flexible plastic packaging, and even your plastic aligner case may be recycled.

To determine which choice is best for you, you should speak with your dentist.

Always keep a few of your most recent Invisalign trays on hand since you never know when you might need them.

Bonus: What Not to Do When Wearing Invisalign/Aligners

Your normal activities shouldn’t be significantly affected by wearing your Invisalign aligners.

However, specialists urge patients to remove them for specific tasks like eating, smoking, chewing gum, cleaning their teeth, and flossing.

Remove aligners when brushing your teeth

Taking the aligners out when brushing your teeth enables you to properly clean every area of your mouth, assisting in the removal of plaque and bacteria.

Remove aligners before you smoke

If you smoke, dentists would urge you to remove your aligners before having a cigarette because the smoke might discolor them and make them more noticeable to others.

Avoid Chewing Gum

Additionally, chewing gum while wearing aligners is discouraged since gum tends to adhere to braces, increasing the risk of dental health issues because plaque will begin to build up on the aligner.


We now know that even though Invisalign trays are highly harmful to the environment, we still require them.

We are crossing our fingers, though that technology will eventually create a technique to properly dispose of them without endangering the environment.
