How to Recycle Invisalign [6 Proper Disposal and Eco-Friendly Options]

Invisalign is a type of clear brace that dentists use to straighten teeth and fix problems with how the teeth fit together. Instead of metal braces, Invisalign uses clear, plastic aligners that are custom-made to fit your teeth. 

One of the reasons why Invisalign is popular is because the aligners are clear and hard to notice compared to metal braces. They are almost invisible when you wear them, which is great for people who are worried about how braces might look.

However, not everyone is a good candidate for Invisalign, so it’s important to talk to a dentist to find out what’s best for you.

Here’s how it works: First, you visit a dentist who is trained in Invisalign. They will examine your teeth and decide if Invisalign is right for you. If it is, they will create a plan for your treatment. This involves taking digital pictures, X-rays, and impressions of your teeth.

Using these records, a series of aligners will be made just for you. Each aligner is slightly different and you wear each one for about two weeks before moving on to the next. As you go through the series, your teeth gradually move into the correct position.

The aligners are removable, so you can take them out when you eat, drink, brush your teeth, and floss. However, for best results, you should wear them for about 20 to 22 hours a day. 

During your treatment, you will have regular check-ups with your dentist to see how you’re progressing and get new sets of aligners. The length of treatment varies depending on how complex your case is, but it usually takes between 6 months and 2 years.

Benefits of recycling aligners, a component of Invisalign.

Recycling aligners, a component of Invisalign treatment, offer multiple benefits by actively contributing to environmental preservation and waste reduction efforts. These include:

  1. Waste Reduction: By recycling aligners, we decrease the amount of plastic waste that would otherwise end up in landfills. Repurposing the materials allows for their reuse, reducing the need for new resources and minimizing the environmental impact caused by discarded aligners.
  1. Resource Conservation: Recycling aligners contribute to the conservation of valuable resources such as energy and raw materials. Instead of manufacturing new aligners from scratch, recycling enables the reuse of existing materials, reducing the demand for new production processes and the associated resource consumption.
  1. Promotion of Sustainability: Recycling aligners actively supports waste reduction efforts, helping to alleviate the overall waste burden on the environment. By embracing recycling, we adopt a more sustainable approach to orthodontic treatment and foster responsible waste management practices.
  1. Promoting Environmental Responsibility: Recycling aligners align with ethical responsibilities and environmental stewardship. It demonstrates a commitment to minimizing waste and making environmentally conscious choices to safeguard our planet for future generations.
  1. Fostering a Sustainable Circular Economy: Recycling aligners contribute to the development of a circular economy, where materials are reused and recycled in a closed-loop system. This approach maximizes resource efficiency, minimizes waste generation, and promotes a sustainable and circular approach to manufacturing and consumption.

It is worth noting that the availability and specific options for recycling aligners may vary depending on your location and the materials used in your aligners. 

It is advisable to consult the manufacturer or your orthodontist to inquire about recycling programs or options available for aligners in your area.

Is it recommended to keep old Invisalign trays?

It is generally not necessary or recommended to keep old Invisalign trays once you have progressed to the next set of aligners. Invisalign treatment involves a series of aligners that are specifically designed to gradually move your teeth into the desired position.

Once you have finished using a particular set of aligners and progressed to the next set, there is typically no need to keep the previous trays. The new aligners will continue the process of shifting your teeth, and the previous trays may no longer fit properly as your teeth move.

However, it’s always a good idea to consult with your orthodontist or dentist regarding specific instructions for your case. They can provide guidance on whether there are any reasons to retain certain aligners or if it is safe and appropriate to dispose of them.

In general, it is recommended to follow the instructions provided by your dental professional and dispose of old aligners in accordance with local waste disposal guidelines.

Recycling your Invisalign aligners is a straightforward and responsible approach that contributes to environmental sustainability. By recycling, you play a part in reducing waste sent to landfills and conserving resources required for the production of new items.

While the recycling options may vary depending on your location and the specific materials used in your aligners, here are some general steps to consider:

#1. Bin Them

After completing your treatment with a set of Invisalign aligners, it is generally recommended to dispose of them by placing them in the regular trash bin. 

When discarding your used aligners, it is a good practice to place them in a sealed bag or wrap them in tissue or paper before disposing of them in the trash bin. This helps prevent any potential contamination or contact with other waste.

In most cases, Invisalign aligners are not designed to be recycled through standard recycling programs. Therefore, it is best to follow the disposal instructions provided by your orthodontist or Invisalign provider.

#2. Treat Them as Medical Waste and Dispose of Them as Such

Used Invisalign aligners should be treated as medical waste and disposed of accordingly. Since aligners come into contact with your mouth and teeth, they can potentially harbor bacteria or contaminants. It is important to follow the disposal guidelines provided by your orthodontist or Invisalign provider.

Typically, used aligners should be placed in a sealed bag or container before being disposed of in the regular trash. This helps minimize any potential contamination and ensures they are securely contained.

It’s important to avoid placing them in recycling bins or attempting to repurpose them for non-medical uses, as aligners are not designed for such purposes.

If you have any specific concerns or questions about the proper disposal of your aligners, it is best to consult with your orthodontist or dental professional. They can provide you with detailed instructions based on your individual circumstances and the materials used in your aligners.

#3. Consult with your Dentist

While some dental offices or orthodontic practices may have recycling programs or partnerships with recycling companies that allow them to recycle Invisalign aligners, it’s important to note that this option may not be universally available.

The ability to recycle Invisalign aligners largely depends on the resources and practices of your specific dental provider. 

If you are interested in recycling your Invisalign aligners, it is recommended to consult with your orthodontist or dentist to inquire about any available recycling programs or options.

They will be able to provide you with specific guidance on whether they can recycle your aligners and any necessary steps or protocols to follow.

While it may be tempting to hold on to your used aligners, it’s important to note that there are certain ways that should be avoided when it comes to recycling them. They include:

#4. Holding on to them

Holding on to your Invisalign aligners is generally not necessary or recommended once you have progressed to the next set. It is more common to dispose of or recycle old aligners after they have served their purpose. 

However, it’s important to follow the guidance of your orthodontist or dental professional regarding the specific instructions for your aligners. They can provide personalized advice on whether there are any reasons to keep certain aligners or if it is safe to dispose of them.

#5. Creative Creepy Stationery Holders

While recycling your used aligners as creative creepy stationery holders may sound like a unique idea, it is important to note that aligners are typically made of specialized medical-grade plastics that may not be easily recyclable through standard recycling programs. 

Therefore, it is generally not recommended to repurpose or recycle used aligners for stationery holders due to the specific materials and their intended use in orthodontic treatment.

However, if you are interested in creating creepy stationery holders, there are numerous other materials and objects you can explore, such as Skull Pen Holders, Spider Web Pencil Cups, Coffin Desk Organizers, Hand-shaped Pen Stands, and Creepy Doll Pencil Holders.

 These options allow you to express your creativity while ensuring the proper recycling and disposal of your used aligners.

Remember to follow the recommended guidelines from your orthodontist or Invisalign provider regarding the disposal of your aligners to maintain hygiene and prevent any unintended consequences.

#6. Creepy Nightstand Decorations

Repurposing your used aligners as creepy nightstand decorations may not be the most suitable option. Aligners are designed for oral health purposes and are typically made of specialized medical-grade plastics that may not be easily repurposed or recycled into decorative items.

However, if you’re looking for creepy nightstand decorations, there are numerous other options available that are specifically designed for decorative purposes.

Consider items such as spooky figurines, eerie candle holders, skull-shaped ornaments, or other Halloween-themed decorations that can create the desired atmosphere.

It is important to prioritize safety and hygiene when selecting decorations for your nightstand. It’s best to choose purpose-made items that are designed for decoration, rather than repurposing items that were originally intended for oral health purposes.

Is Invisalign considered environmentally friendly?

Invisalign aligners are better for the environment than traditional braces for a few reasons:

  1. Less Waste: Invisalign aligners are made using special technology that helps reduce the amount of material wasted during production. This means less stuff gets thrown away.
  2. Saves Energy: The way Invisalign aligners are made with computers and fancy machines helps use less energy. It’s like using a smart tool that gets the job done efficiently.
  3. Safe Materials: Invisalign aligners are made from strong and safe plastics that are chosen carefully for your mouth. They are designed to be durable and flexible while also being safe to use.
  4. Personalized Treatment: Invisalign aligners are customized just for you. This means they can move your teeth in the most efficient way, potentially reducing the time needed for treatment. A shorter treatment time can be better for the environment.
  5. Recycling Possibilities: While not available everywhere, some dental offices might have recycling programs for Invisalign aligners. This allows for the possibility of reusing or recycling the aligners, which is good for the environment. 

It’s important to remember that no dental treatment is completely free from environmental impact. But compared to traditional braces, Invisalign aligners are often seen as a more eco-friendly choice because they use resources more efficiently and have the potential for recycling.


In conclusion, although recycling options for Invisalign aligners may be limited, it’s important to prioritize sustainable practices in dental care. Consult your orthodontist for information on any available recycling programs or proper disposal methods. 

While responsible disposal of medical waste is crucial, it’s vital to support ongoing efforts to enhance sustainability in orthodontics. 

By staying informed and supporting eco-friendly dental practices, we can contribute to a healthier planet and a brighter smile.


Are Invisalign bags able to be recycled?

Invisalign bags, the small plastic bags used to store Invisalign aligners, are typically not easily recyclable through regular recycling programs. These bags are usually made from a type of plastic that is not commonly accepted by recycling centers.

However, there might be some specific places that specialize in recycling certain types of plastic, including these bags. 

It’s a good idea to check with your local recycling center or waste management facility to see if they accept this type of plastic bag for recycling. They will have the most up-to-date information on recycling options in your area.

If recycling is not available for Invisalign bags where you live, the best way to dispose of them is by placing them in the regular trash. 

However, you can consider reusing the bags for other purposes, such as storing small items or for travel, if they are clean and in good condition. 
Remember to follow the recycling guidelines provided by your local waste management authorities to help protect the environment.

Does Invisalign have a negative impact on the environment?

Invisalign, like any other dental treatment, has some environmental impact, but it is generally considered to have a lower environmental impact compared to traditional braces.

The aligners are made from durable and flexible medical-grade plastic, which can have implications for resource consumption and greenhouse gas emissions. Precision manufacturing and digital processes help minimize waste, and energy-efficient technologies are used. 

Disposal should be done as medical waste, and while aligners are not easily recyclable through regular programs, some dental offices may have specialized recycling options. 

It’s recommended to consult with your orthodontist for proper disposal guidance. Efforts are being made to improve sustainability and waste management in dental treatments.
