Should You Sleep with Your Invisalign Aligners In?

Invisalign has completely changed the world of orthodontics by offering a discreet and convenient alternative to traditional braces. These modern clear aligners are popular due to their effectiveness in straightening teeth without the visibility and discomfort associated with metal braces. As you start your journey to a straighter smile, you may wonder whether you should wear your Invisalign aligners whilst you are sleeping. We will explore the considerations and recommendations surrounding the question ‘Should you sleep with Invisalign?’

How Important is it to Consistently Wear Invisalign Aligners? 

One of the key factors contributing to the success and progression of Invisalign treatment is consistent wear. Orthodontists usually recommend wearing the aligners for 20 to 22 hours a day, which you will be told at your invisalign consultation, removing them only for eating, drinking (except for water), and cleaning your teeth. This consistency ensures that your teeth are gently and continuously guided into their new desired positions.

Sleeping with Invisalign

The general consensus among orthodontic professionals is that wearing your Invisalign aligners while you sleep is extremely important to achieve optimal results. 

Here are some reasons why:

Continuous Progress: Invisalign retainers work by applying constant but gentle pressure on your teeth. By wearing them while you sleep, you increase the duration of this pressure, which will lead to more efficient tooth movement.

Comfort and Adaptation: Wearing Invisalign aligners while you sleep allows your teeth to adjust gradually without the conscious awareness that comes with daytime wear. This can be particularly beneficial during the initial stages of treatment when some people may find Invisalign quite uncomfortable.

Protecting Your Progress: If you stop wearing your aligners at night, you are at risk of prolonging your orthodontic treatment. Sometimes, it may even lead to regression, reversing the positive changes your teeth have undergone during the day.

Tips for Sleeping with Your Invisalign

We recommend following these tips to improve your experience and ensure you are comfortable with your aligners at night:

Maintain Good Oral Hygiene: Brush and floss your teeth before putting in your aligners at night to prevent the buildup of unwanted bacteria and plaque.

Correct Aligner Seating: Before bedtime, make sure your aligners are positioned correctly on your teeth. This helps ensure that they stay in place throughout the night.

Stay Hydrated: Drinking water before bed is essential for overall health and you don’t need to remove your aligners before doing so.


Overall, the consensus among orthodontic professionals is clear: sleeping with Invisalign is very important for achieving the best results. Consistent wear, especially during the night, ensures that your teeth undergo the necessary continuous pressure for effective and timely movement. By incorporating your aligners into your nightly routine, you’re not only maximising the potential of your treatment but also ensuring a smooth and successful journey to a straighter, more confident smile.
