Tooth Sensitivity and Invisalign: How to Manage Discomfort?

The question of pain is a legitimate concern for anyone considering orthodontic treatment. Although Invisalign is known for its great comfort, it can cause some discomfort, especially at the beginning. Rest assured, this sensation is most often a positive sign that your teeth are starting to move as planned.

What causes discomfort with Invisalign?

The very principle of Invisalign is to achieve dental alignment by applying light but constant forces. This pressure, exerted by the aligners on the teeth, triggers a biological response that allows teeth to move. The sensation of discomfort, often described as "tension" or "sensitivity," stems directly from this activity.

This discomfort is mainly felt:

• When installing the very first pair of aligners.
• During the first 24 to 48 hours after switching to a new set of aligners.

Different forms of discomfort you may experience

Discomfort can manifest in several ways, but it generally remains moderate and short-lived.

Tooth tension and sensitivity

This is the most common sensation. One or more teeth may become sensitive, particularly when chewing. This is a completely normal phenomenon indicating that orthodontic forces are being applied correctly.

Tongue or cheek irritation

Sometimes the edges of a new aligner may rub slightly against the soft tissues of the mouth. This is much less frequent and intense than with traditional braces, but it can occur.

Discomfort related to attachments

Invisalign attachments, those small composite bumps bonded to teeth, can initially create a rough sensation. However, cheeks and lips adapt very quickly.

How to manage and soothe discomfort?

Fortunately, simple tips exist to make these sensitivity phases more bearable:

• Change aligners in the evening at bedtime: Put on your new set of aligners just before sleeping. The initial pressure will be exerted during the night, and discomfort will often be reduced by morning.
• Adopt a soft diet: On the first day after a change, favor foods requiring little chewing (soups, purees, yogurts).
• Use cold: Drinking cool water or applying an ice pack to your cheek can help relieve sensitivity.
• Take a painkiller: If needed, a simple painkiller like paracetamol can be used. It's advisable to avoid anti-inflammatories (like ibuprofen), as some studies suggest they could slow tooth movement.
• Use orthodontic wax: If an aligner edge irritates you, a small piece of orthodontic wax can be applied to protect the sensitive area.
• Continue wearing aligners: The best way to get past sensitivity is to continue wearing aligners. Removing them would only prolong the adaptation period.

When should you be concerned?

Moderate and temporary discomfort is normal. However, it's recommended to contact your practitioner if you notice:

• Acute, severe pain that doesn't subside.
• Discomfort that persists beyond 2 or 3 days.
• An injury or irritation that doesn't heal.

It's also essential to maintain impeccable hygiene to rule out any pain related to a cavity or gum problem. Remember to always clean your aligners and teeth after each meal.

Conclusion: temporary discomfort for a permanent result

Invisalign is one of the most comfortable orthodontic solutions on the market. The slight discomfort sometimes felt is a positive sign that testifies to the treatment's effectiveness. By applying a few simple tips, this discomfort is entirely manageable and short-lived, allowing you to quickly enjoy the benefits of a perfectly aligned smile.
