How often do you need to soak Invisalign trays?

When it comes to orthodontic treatment, Invisalign has become a popular and effective option for straightening teeth. These clear aligners offer a discreet and comfortable way to achieve a beautiful smile. However, proper care and maintenance of Invisalign trays are essential to ensure their effectiveness and longevity. One key aspect of maintaining the cleanliness and hygiene of Invisalign trays is regular soaking. In this article, we will discuss how often you need to soak Invisalign trays and why it is an important part of their care routine.

Why soaking Invisalign trays is necessary

Regular brushing is important for removing food particles and bacteria from your Invisalign trays, but there are some gunk that simple brushing won’t be able to take care of. Soaking Invisalign trays serves as a more thorough cleaning method to tackle those hard-to-reach areas. Here are a few reasons why soaking is necessary:

Inability of regular brushing to remove all debris

Although brushing your Invisalign trays is an important part of their maintenance, it may not be sufficient to remove all debris. The aligners have small crevices and tight spaces where food particles and bacteria can accumulate. Soaking them in a cleaning solution helps to loosen and break down stubborn gunk, making it easier to remove when brushing.

Effectiveness of soaking in breaking down and removing gunk

Soaking Invisalign trays in a cleaning solution helps to break down tough stains, plaque, and bacteria. Different cleaning solutions have specific ingredients that aid in the removal of debris and prevent bacterial buildup. Soaking also allows the solution to penetrate those hard-to-reach areas, ensuring a thorough cleaning of the trays.

Prevention of bacterial buildup and foul odors

When Invisalign trays are not properly cleaned, bacteria can accumulate, leading to bad breath and potential oral health issues. Soaking helps to eliminate bacteria and prevent their buildup, minimizing the risk of foul odors and maintaining overall oral hygiene.

Recommended frequency of soaking

Experts recommend soaking Invisalign trays once a day as part of their regular care routine. This daily soaking ensures consistent cleanliness and hygiene for your aligners throughout the treatment process. However, it is important to note that over-soaking can have potential negative effects on the trays.

Over-soaking and potential negative effects

While regular soaking is necessary, over-soaking Invisalign trays can weaken their material and lead to discoloration or distortion. It is important to follow the recommended duration for soaking and not exceed the instructions provided by your orthodontist or the cleaning solution manufacturer.

Proper method of soaking Invisalign trays

To ensure effective cleaning and maintenance of your Invisalign trays, it is important to follow the proper method of soaking. Here are some important steps to follow:

Choosing the right soaking solution

There are different types of cleaning solutions available for Invisalign trays. It is important to choose a solution that is specifically formulated for cleaning aligners. Avoid using harsh chemicals such as bleach or abrasive cleaners, as they can damage the trays.

Using lukewarm water for soaking

When soaking your Invisalign trays, use lukewarm water. Hot water can potentially warp or damage the trays, compromising their fit and effectiveness. Avoid using cold water as well, as it may not effectively loosen debris or kill bacteria.

Duration of soaking

The general guideline for soaking Invisalign trays is 15-20 minutes. This duration allows sufficient time for the cleaning solution to work effectively. However, it is important to adjust the soaking time based on specific instructions provided by your orthodontist or the cleaning solution manufacturer.

Additional tips for maintaining Invisalign trays

In addition to regular soaking, here are some additional tips to help you maintain the cleanliness and hygiene of your Invisalign trays:

Rinsing trays before and after soaking

Before soaking, rinse your Invisalign trays with water to remove any loose debris. After soaking, make sure to thoroughly rinse the trays to remove any residue from the cleaning solution.

Brushing trays gently with a soft toothbrush

After soaking and rinsing your Invisalign trays, use a soft toothbrush to gently brush them. Be cautious not to use a toothbrush with hard bristles, as it can scratch or damage the trays.

Storing trays in a clean and dry container when not in use

When you are not wearing your Invisalign trays, store them in a clean and dry container. This helps to prevent the accumulation of debris and bacteria while keeping them safely stored.

Common mistakes to avoid when soaking Invisalign trays

To ensure optimal care for your Invisalign trays, avoid the following common mistakes when soaking:

Using hot water for soaking

As mentioned earlier, hot water can warp or damage the trays. Always use lukewarm water for soaking to maintain the proper form and fit of the aligners.

Soaking trays for excessive durations

While it may be tempting to soak your Invisalign trays for longer periods, it is important to follow the recommended duration provided by your orthodontist or the cleaning solution manufacturer. Excessive soaking can compromise the integrity of the trays and lead to discoloration or distortion.

Neglecting to rinse or thoroughly clean trays before reinserting

After soaking, it is crucial to rinse your Invisalign trays thoroughly to remove any residue or cleaning solution. Neglecting to do so can lead to discomfort or discomfort when you wear them again.


Regular soaking is an indispensable part of maintaining the cleanliness and hygiene of Invisalign trays. By following the recommended frequency of daily soaking, using the proper method, and avoiding common mistakes, you can ensure that your Invisalign trays stay clean, odor-free, and effective throughout your orthodontic treatment journey. Remember to consult your orthodontist for specific instructions on soaking and cleaning your Invisalign trays, as they will provide personalized guidance based on your unique dental needs.
