Invisalign Retainers: 4 Types & Guide to Retainers and Aftercare

Invisalign treatment transformed our perception of teeth straightening. Unlike traditional braces, Invisalign aligners are almost invisible to the eye and present a comfortable solution for correcting dental alignment. However, the completion of the Invisalign treatment is the beginning of a critical phase—adhering to the use of retainers.

Post-treatment retainers maintain the results achieved through months, or sometimes years, of Invisalign treatment. Without them, teeth have a natural tendency to revert to their original positions, undoing the hard-earned results.

This article will guide patients through the different types of Invisalign retainers and provide essential insights into retainer care and aftercare, ensuring long-lasting, beautiful smiles.

What is Invisalign Retainer?

Invisalign retainers are important for post-treatment care after using Invisalign aligners. They are crafted from thin, transparent plastic and resemble the aligners used during treatment.

Retainers differ from Invisalign aligners in their function and materials. Invisalign aligners gradually move teeth using pressure, while retainers maintain the final tooth position without actively shifting them.

In terms of materials, Invisalign aligners are made from a unique medical-grade thermoplastic material that is thinner and more flexible than most retainers. Retainers, on the other hand, are usually made of clear plastic and are custom-made to fit the patient’s teeth contours.

Types of Invisalign Retainers

There are different types of Invisalign retainers. Options include the premium Vivera retainers, a choice celebrated for its robustness, clarity, and personalised fit. While Vivera retainers are a popular choice for those who prioritise strength, aesthetics, and a customised fit, alternative types of retainers like Hawley, bonded, and Essix retainers offer their unique set of benefits. These alternatives address different needs and preferences, ensuring there is a suitable option for everyone.

Vivera Retainers

Vivera Retainers

Vivera retainers are distinguished by their exceptional strength, crystal-clear appearance, and tailored fitting. These retainers are fabricated from a proprietary material that is 30% stronger than other clear retainer types. This significant strength advantage not only prolongs their lifespan but also provides superior resistance against teeth shifting, ensuring that your investment in a perfect smile is well protected.

Hawley Retainers

Hawley Retainers

Hawley retainers, a traditional choice in teeth alignment maintenance, stand out for their durability and adjustability. Crafted from a combination of metal wire that wraps around the teeth and an acrylic base that sits on the roof of the mouth, these retainers are easily recognisable. Their design allows for minor adjustments to be made, ensuring a perfect fit throughout their use.

One of the key advantages of Hawley retainers is their longevity, which can last for many years. However, they are more visible than clear retainers, which may be a drawback for those who prefer a more discreet option. The metal wires can also be uncomfortable for some users, especially initially.

Bonded Retainers (Fixed Retainers)

Permanent Retainers

Bonded retainers, often referred to as fixed retainers, consist of a thin wire permanently attached to the inner surface of the upper or lower front teeth. This subtle approach to teeth retention is virtually invisible to others, offering a cosmetic advantage for those who are conscious about their appearance post-orthodontic treatment.

The permanent nature of a fixed retainer makes it a reliable choice for those looking to maintain their orthodontic results over the long term without the need for remembrance or compliance in wearing a removable retainer regularly. However, this can also be seen as a disadvantage. They require meticulous oral hygiene practices to prevent plaque build-up around the retainer wire, leading to gum disease or tooth decay if neglected.

Additionally, because they are permanently fixed, any damage or breakage necessitates a visit to an orthodontist for repair or replacement, which may incur additional costs.

Essix retainers

Essix Retainer

Essix retainers are similar to the Invisalign trays. They are made from a clear PVC or polyurethane material, which provides a snug fit over the entire arch of the teeth. One of the main advantages of Essix retainers is their invisibility, making them a more aesthetically pleasing option compared to traditional metal retainers.

Essix retainer is generally considered to be less durable than a Vivera retainer. The material from which Essix retainers are made is thinner and can be more prone to cracks and breaks if not handled carefully.

Why Do You Need Invisalign Retainers?

Over time, it is natural for your teeth to shift due to various factors such as ageing, teeth grinding, or even the pressure exerted by daily activities like chewing. This gradual movement can potentially compromise the straightness of your teeth achieved through orthodontic treatments, leading to what is known as relapse.

After investing a significant amount in Invisalign treatments to achieve that perfect smile, the risk of relapse without the use of retainers could mean your teeth gradually returning to their pre-treatment positions. This not only undermines the investment made in your orthodontic care but also might entail additional costs for corrective treatments in the future.

While the cost of Invisalign retainers might be an added expense, it’s essential to consider them as a long-term investment in maintaining your smile. Additionally, it’s worth exploring whether your dental insurance plan offers coverage for retainers, as some insurance plans may partially or fully cover its cost, mitigating the financial impact of this essential post-treatment care.

Caring for Your Invisalign Retainers

Invisalign retainers are like any other orthodontic treatment- they require proper care to work effectively. Some tips to ensure they stay clean and functional include cleaning routines, storage and knowing their do’s and don’ts.

Cleaning Routines

It’s crucial to adhere to a daily cleaning routine to maintain the integrity and cleanliness of your Invisalign retainers. Begin by using a soft toothbrush – this is gentle enough to avoid scratching the retainers. It is advisable to use clear, antibacterial soap as your primary cleaning solution because it is effective in eliminating bacteria without clouding or discolouring the aligners. Avoid using toothpaste, especially those that are abrasive, as they can scratch the surface, making the retainers less invisible.

Equally important is the practice of soaking your Invisalign retainers. You should submerge them in either the cleaning solution recommended by your dentist or in a denture cleaner. Please ensure to follow the soaking duration as advised by your dental professional. This soaking process not only helps in deep cleaning but also ensures the retainers remain clear and free from harmful bacteria.

Always use the designated storage case provided to keep your retainers safe when not in use. This not only prevents damage but also minimises the risk of losing them. It’s particularly easy to misplace or accidentally throw them away if left out in the open, such as on a napkin during meals.

When travelling, it’s wise to bring along extra cleaning solutions and a spare storage case. This ensures that, no matter where you are, you can maintain your cleaning routine and have a safe place to store your retainers. Packing a small, portable cleaning kit, including the essentials, can greatly ease the maintenance of your Invisalign retainers while away from home.

Do’s and Dont’s

Taking proper care of your Invisalign retainers is essential for their longevity and effectiveness. Here are some important habits to adopt:


  • Rinse your retainers with cold water every time you remove them to minimise bacterial build-up.
  • Keep your retainers away from high temperatures; hot drinks and hot water can warp the plastic.
  • Always place your Invisalign retainers in their case when you’re not wearing them to avoid damage or loss.


  • Avoid exposing your retainers to harsh chemicals, including alcohol-based mouthwashes, as these can damage the material.
  • Do not use your retainers as a substitute for chewing gum. Chewing can bend or warp them, affecting their fit and effectiveness.
  • Refrain from leaving your retainers out in the open when not in use, as exposure to air can dry them out and make them brittle.

How Long to Wear Invisalign Retainers After Treatment?

Following the completion of Invisalign treatment, it is recommended to wear retainers full-time for a specific period, usually around 4 to 6 months. This protocol is crucial to maintain the teeth in their new positions until they stabilise.

After this initial phase, the need to wear the retainers full-time gradually decreases. Patients may then be advised to wear them only at night. However, it cannot be overstressed how essential it is to adhere strictly to the specific instructions provided by your dentist or orthodontist, as the precise duration can vary based on individual treatment plans and the complexity of the dental corrections.

In the long term, many orthodontists suggest the occasional nighttime wear of retainers indefinitely to prevent teeth to have the tendency to naturally shift back to their original positions over time. This practice ensures the longevity of the treatment results and helps maintain a straight and healthy smile.
