Does Invisalign Cause Dry Mouth

Table of Contents

When considering orthodontic treatment options, many people turn to Invisalign as an alternative to traditional braces. Invisalign offers a discreet and convenient way to straighten teeth using clear aligners. However, some individuals have raised concerns about the potential side effect of dry mouth while undergoing Invisalign treatment. So, the question arises, does Invisalign cause dry mouth?


In this article, we will explore the connection between Invisalign and dry mouth, address common queries related to this topic, and provide helpful insights on managing and treating dry mouth caused by Invisalign.

How Does Invisalign Work?

Before delving into the issue of dry mouth, let’s briefly understand how Invisalign works. Invisalign is an innovative teeth-straightening method that involves wearing a series of custom-made aligners. These aligners are made from smooth, BPA-free plastic and are virtually invisible when worn.


Moreover, employs a series of custom-made clear aligners to gradually shift teeth into their desired positions. The treatment gradually shifts the teeth into their desired position, following a customized treatment plan designed by an orthodontist or dentist.


Unlike traditional braces, Invisalign aligners are removable and virtually invisible, making them a popular choice for those seeking a more discreet orthodontic solution. These aligners are typically worn for 20 to 22 hours per day, and they are replaced with a new set every one to two weeks, depending on the treatment plan.

The Relationship between Invisalign and Dry Mouth

One of the commonly asked questions is, can Invisalign cause dry mouth. While Invisalign treatment itself doesn’t directly cause dry mouth, some individuals may experience this condition as a side effect.

Does Invisalign Make Your Mouth Dry?

The primary reason behind this is that wearing the aligners can affect saliva flow, leading to temporary dryness in the mouth. This can be attributed to a few factors:

  1. Increased Airflow: Invisalign aligners are designed to fit snugly over your teeth, but they may create a slight space between the aligners and your teeth, allowing more air to circulate in your mouth. This increased airflow can contribute to the sensation of dryness.
  2. Saliva Production: Wearing Invisalign aligners may result in a natural increase in saliva production as your mouth adjusts to the presence of the aligners. This initial adjustment period may cause a temporary imbalance in saliva production, leading to a feeling of dryness.
  3. Mouth Breathing: Some individuals tend to breathe through their mouths rather than their noses, especially during sleep. Invisalign aligners can potentially exacerbate this habit, as they cover the teeth and can make nasal breathing slightly more challenging. Mouth breathing can lead to dry mouth symptoms.

Why Does Invisalign Sometimes Result in Dry Mouth?

Invisalign aligners are designed to fit snugly over the teeth, creating a barrier between the aligners and the natural flow of saliva. This temporary obstruction can reduce saliva production, causing dry mouth sensations for some patients. However, it’s important to note that this side effect is typically mild and transient.

How to Treat Dry Mouth from Invisalign

If you are experiencing dry mouth during your Invisalign treatment, there are several steps you can take to alleviate the discomfort:

  1. Stay Hydrated: Drink plenty of water throughout the day to maintain proper hydration and promote saliva production.
  2. Chew Sugar-Free Gum: Chewing sugar-free gum stimulates saliva flow and can help relieve dry mouth symptoms.
  3. Use Moisturizing Mouthwash: Rinse your mouth with an alcohol-free, moisturizing mouthwash to keep your mouth hydrated.
  4. Practice Good Oral Hygiene: Brush and floss regularly to maintain oral health and reduce the risk of dry mouth-related complications, such as tooth decay.
  5. Avoid Triggering Substances: Stay away from substances that can further contribute to dry mouths, such as tobacco, caffeine, and alcohol.

If your dry mouth symptoms persist or become severe, it is advisable to consult your dentist or orthodontist for further evaluation and guidance.

Does Invisalign Dry Mouth Go Away?

For most individuals, dry mouth from Invisalign is a temporary side effect that improves over time. As your mouth adjusts to the aligners, saliva flow typically returns to normal. However, everyone’s experience may vary, and in some cases, dry mouth may persist throughout the Invisalign treatment.

It’s important to note that dry mouth can have various causes, including medications, medical conditions, and lifestyle factors. If you suspect that your dry mouth is unrelated to Invisalign or persists even after completing your treatment, consult a healthcare professional for a thorough evaluation.

Managing Dry Mouth with Invisalign:

While Invisalign offers numerous benefits for teeth alignment, it can potentially cause dry mouth with Invisalign due to the presence of aligners covering the teeth. However, by following the tips mentioned above and maintaining good oral hygiene, you can manage and alleviate the symptoms of dry mouth during your Invisalign treatment. It’s important to remember that everyone’s experience may vary, and if you have concerns or the dry mouth persists, it’s best to consult your dentist for further guidance and personalized recommendations.


In some cases, you may experience discomfort from dry mouth despite implementing preventive measures. In such situations, using a dry mouth spray can provide additional relief. Dry mouth sprays are designed to lubricate the mouth and provide moisture, alleviating the uncomfortable sensation.


Remember, your oral health is essential, and addressing any concerns promptly can ensure a positive experience with your Invisalign treatment. So, don’t hesitate to seek professional advice and explore suitable solutions to make your journey toward a straighter smile as comfortable as possible.
