In the process of achieving a straight smile, many patients choose Invisalign as a discreet and more comfortable solution than braces. But what steps are required after the treatment concludes? This article examines post-Invisalign care, discussing the importance and purpose of retainers. We’ll address questions about the consequences of not wearing them, guidelines on usage frequency, tips for proper care, and insights on when a replacement might be necessary.

Do I Need a Retainer After the Treatment?

Retainers are orthodontic devices that are custom-made for individual patients, and they are typically used after braces or other orthodontic treatments to maintain the new position of teeth. Their primary role is to “retain” the teeth in their corrected positions, preventing them from shifting back to their original, misaligned state.

Role of Retainers:

  • Maintain Corrected Position: Once braces or aligners have moved teeth to their desired positions, it takes time for the surrounding gums and bone to stabilize around the new tooth position. Retainers ensure that teeth do not drift back to their original positions during this stabilization period.
  • Compensate for Natural Changes: As we age, our teeth naturally tend to shift. Wearing a retainer long-term, even if only at night, can help counteract these changes.
  • Post-Treatment Stabilization: The period immediately after braces or aligners are removed is the most critical time to wear a retainer because teeth are most susceptible to movement during this time.

Worth Knowing

A study featured in the American Journal of Orthodontics and Dentofacial Orthopedics reveals that two years after receiving their retainers, 19% of patients had stopped wearing them altogether, while 81% continued to wear their retainers at least once a week.

What Happens If You Do Not Wear a Retainer?

If you do not wear a retainer after orthodontic treatment, several things can happen, and the specific outcomes can vary from person to person. Here are some potential consequences:

  • Teeth Shifting: The most immediate and apparent consequence of not wearing a retainer is the potential for teeth to shift back to their previous, misaligned positions. This is especially likely soon after braces are removed when teeth are more unstable.
  • Loss of Orthodontic Investment: Invisalign can be expensive and time-consuming. By not wearing a retainer, you risk undoing all the hard work and financial investment that went into achieving straight teeth.
  • Bite Misalignment: If the teeth begin to shift, it can lead to a misaligned bite, which can result in uneven wear on the teeth, difficulty in chewing, or even temporomandibular joint (TMJ) problems.
  • Aesthetic Concerns: One of the primary reasons people get Invisalign is for cosmetic reasons – to have a straighter, more appealing smile. Not wearing a retainer can compromise the aesthetics of one’s smile.
  • Increased Risk of Dental Issues: Misaligned teeth can be harder to clean effectively, leading to a greater risk of dental problems such as cavities and gum disease.
  • Need for Re-treatment: In some cases, if the teeth have shifted significantly due to not wearing a retainer, the only solution to correct them might be undergoing orthodontic treatment again.
  • Wasted Time: Aside from financial investment, undergoing orthodontic treatment is a significant time commitment. Not wearing a retainer and allowing teeth to shift can result in wasted time, especially if another round of treatment is required.
  • Bone and Soft Tissue Changes: The periodontal ligament, which is the soft tissue that holds teeth in place, needs time to adjust to the new positions of the teeth after Invisalign is removed. If a retainer isn’t worn, the teeth can shift as this tissue remodels. Furthermore, the alveolar bone around the teeth also undergoes remodeling after orthodontic treatment and requires stabilization from a retainer to maintain the new positions of the teeth.

How Often Do You Have to Wear My Retainer?

Initial Post-Treatment Phase

During the initial post-treatment phase, it’s important to wear the Invisalign retainer for 22+ hours per day for 3 to 6 months. This ensures your teeth remain in place and adapt to their new positions. Wearing the retainer consistently during this period prevents unwanted tooth movement, ensuring the longevity of your Invisalign treatment results.

Long-Term Maintenance

After the initial post-treatment phase, you might only need to wear your retainer 3 to 5 nights per week for the rest of your life. Continuous retainer wear helps maintain your teeth’s alignment, counteracting the gradual movement that tends to occur as you get older. To keep your retainer in good condition, it’s recommended to replace it every 6 months to avoid degradation. Proper care and long-term maintenance of your retainer will help preserve the beautiful results achieved through Invisalign.

How to Care for Your Invisalign Retainers


To maintain your Invisalign retainers, clean them regularly using a soft-bristled toothbrush and a gentle, clear liquid soap. Rinse the aligner under lukewarm water, making sure it isn’t too hot or too cold. Use small, circular motions to gently brush the entire retainer, both inside and out. Avoid using toothpaste, as it may scratch the plastic. This routine will help keep your aligners bacteria-free and lasting for years to come.

Proper storage is essential for extending the life of your Invisalign retainers. When not in use, store them in a dedicated retainer case to protect them from dirt, damage, and deformation. Avoid exposing the retainers to extreme temperatures, as this may cause warping. 


When Should You Replace Your Retainer?

Retainers are an important part of maintaining your smile after orthodontic treatment. Typically, retainers should be replaced every 6 to 12 months, though some may last up to 2 years. Factors that affect replacement include daily wear, material quality, and proper care. It’s important to regularly inspect your retainer for signs of wear or damage to ensure it’s effectively maintaining your teeth’s alignment.

What to Do If You Break or Lose Your Retainer?

If you break or lose your retainer, it’s important to take action quickly to prevent teeth from shifting. Here are the steps to follow:

  1. Contact your orthodontist: They can advise you on the best course of action and provide a replacement if necessary.
  2. Order a replacement online if your orthodontist is unavailable: Services like Retainers For Life or Vivera retainers offer convenient ways to obtain a new set.
  3. Wear a temporary retainer or aligner tray: If you have a backup retainer or aligner, wear it until you receive your new one.

Remember, maintaining a consistent retainer regimen is very important for preserving your smile, so don’t hesitate to take action if issues arise.

Are Invisalign Retainers for Life?

In conclusion, maintaining oral health after Invisalign involves using retainers to preserve the alignment achieved. Regular use is crucial, particularly right after treatment, with recommendations suggesting nightly wear indefinitely to counter natural teeth movement over time.

Proper care, including cleaning and storing retainers correctly, extends their life, while timely replacement ensures ongoing effectiveness. If issues arise, prompt action, such as consulting an orthodontist or ordering replacements, is essential to prevent teeth from shifting back.

Frequently Asked Questions

How long should Invisalign retainers be worn daily?

In the initial months after completing Invisalign treatment, retainers should be worn for up to 22 hours a day, removing them only for eating and oral hygiene activities. After three to six months, most patients can transition to wearing retainers only at night.

Are Vivera retainers suitable for long-term use?

Yes, Vivera retainers are designed for long-term use to maintain post-treatment teeth positions. They’re crafted from a durable thermoplastic material, making them more robust than some other clear retainers. However, like all retainers, they’re subject to wear and tear. For optimal performance, they might need replacement every 1-2 years based on usage and individual factors. 

Do Invisalign retainers cause discomfort?

Invisalign retainers are made from a smooth, clear plastic material that is custom-fit for your teeth. While some initial discomfort may be experienced as your teeth adjust to the retainer, this should subside within a few days.

Is a permanent retainer necessary after Invisalign treatment?

Permanent retainers may be recommended for some patients to provide additional support and maintain teeth alignment after Invisalign treatment. However, this decision will be determined by your specific orthodontic needs and your orthodontist’s recommendations.

How to maintain teeth alignment after Invisalign?

To maintain teeth alignment after Invisalign treatment, it’s important to wear your prescribed retainer as instructed by your orthodontist. Additionally, maintaining good oral hygiene practices, like regular brushing and flossing, and attending regular dental check-ups will help keep your smile healthy and aligned.
