Dry Mouth With Braces & Invisalign (What is Xerostomia)

Last Updated on May 4, 2025 by Gio Greenard

Dry mouth, also known as xerostomia, is a common issue for people undergoing orthodontic treatment, whether with traditional braces or Invisalign. It occurs when the mouth doesn’t produce enough saliva, leading to discomfort, difficulty chewing, and an increased risk of tooth decay. Below, we explore the causes of dry mouth during treatment and practical solutions to keep your mouth hydrated and healthy.

What Causes Dry Mouth with Braces and Invisalign?

Several factors contribute to dry mouth during orthodontic treatment:

• Reduced Saliva Flow: Braces or Invisalign aligners can obstruct saliva from reaching teeth, reducing the mouth’s natural defense against bacteria.
• Mouth Breathing: Many people with orthodontic appliances breathe through their mouth, especially while sleeping, leading to dryness.
• Diet & Lifestyle: Sugary, acidic, or caffeinated drinks, smoking, and alcohol can worsen dry mouth.
• Medications: Some prescription drugs, including pain relievers, can contribute to xerostomia.

With Invisalign, dry mouth is often more noticeable because aligners cover the teeth, reducing natural saliva flow. Unlike braces, where saliva can still reach the teeth and gums, aligners act as a barrier, making hydration even more important.

Symptoms of Dry Mouth

Individuals with braces or Invisalign may experience:

• Difficulty speaking, chewing, or swallowing
• A persistent dry or sticky feeling in the mouth
• Swollen or irritated gums
• Increased plaque buildup, bad breath, or tooth sensitivity

Does Dry Mouth Increase the Risk of Tooth Decay?

Yes. Without enough saliva to neutralize acids and wash away food particles, plaque accumulates more easily, increasing the risk of:

• Tooth decay
• Gum disease
• Mouth sores or infections

With Invisalign, the risk may be even higher if food particles get trapped under the aligners. Without sufficient saliva circulation, bacteria can multiply quickly.

Dry Mouth Prevention & Treatment Strategies

The good news is that dry mouth can be managed with simple strategies.

How Long Does Dry Mouth Last with Braces or Invisalign?

For most people, dry mouth symptoms improve as they adjust to their orthodontic treatment. However, Invisalign users may experience persistent dryness due to the aligners’ coverage of the teeth. Staying hydrated and following the above steps can help reduce discomfort.

When to See an Orthodontist

If dry mouth persists despite trying these solutions, it is best to consult your orthodontist. Severe dry mouth may require professional treatment or adjustments to your oral care routine.

Conclusion

Dry mouth is a common challenge for people with braces and Invisalign, but it can be managed effectively. By staying hydrated, adjusting your diet, and using saliva-stimulating remedies, you can keep your mouth comfortable and healthy throughout your orthodontic treatment.
