Clear Aligners and Dental Sensitivity: Managing Discomfort During Treatment

Dental Sensitivity

Clear aligners have transformed orthodontic treatment by providing a discrete and comfortable alternative to traditional braces. They have become increasingly popular for straightening teeth and correcting misalignments, providing a convenient solution for adults and teenagers alike. However, as with any orthodontic treatment, some patients may experience dental sensitivity during their clear aligner journey.

Understanding Clear Aligners

Clear aligners are transparent, custom-made trays that gently shift teeth into their desired positions over time. Unlike conventional braces, clear aligners are removable, allowing for easy cleaning and eating. The treatment process typically involves wearing a series of aligners for a specified period, usually around two weeks per set, until the desired alignment is achieved.

The Connection between Clear Aligners and Dental Sensitivity

Dental sensitivity is a common side effect experienced by many individuals undergoing clear aligner treatment. This sensitivity is primarily due to the pressure exerted on the teeth to shift them into their new positions. As the aligners gently push and move the teeth, the surrounding gums and bone may become temporarily inflamed, leading to sensitivity.

Causes of Dental Sensitivity with Clear Aligners

Pressure on Teeth

As the aligners work to move the teeth, it is natural for patients to feel some pressure on their teeth. This pressure can lead to temporary sensitivity, especially during the first few days of each new aligner tray.

Gum Irritation

Clear aligners may slightly irritate the gums as they put pressure on the teeth. This irritation can cause discomfort and sensitivity in the gum area.

Bone Remodeling

The process of teeth movement involves bone remodeling, where the bone surrounding the teeth adjusts to accommodate the new tooth positions. This can lead to sensitivity in the jaw area.

Temperature Changes

Some patients may experience increased sensitivity to hot or cold temperatures during clear aligner treatment. This heightened sensitivity is a common reaction to the pressure and movement of the teeth.

Managing Dental Sensitivity

Use Orthodontic Wax

If you experience any irritation from the aligners rubbing against your cheeks or gums, orthodontic wax can provide relief. Apply a small amount of wax to the troublesome areas to create a smooth surface.

Chew Soft Foods

During the first few days of wearing a new set of aligners, stick to softer foods to minimize discomfort while chewing.

Over-the-Counter Pain Relievers

Non-prescription pain relievers like ibuprofen or acetaminophen can help reduce sensitivity and discomfort. Always follow the recommended dosage and consult your dentist if you have any concerns.

Avoid Hard and Sticky Foods

Stay away from hard or sticky foods that can potentially damage your aligners and worsen sensitivity.

Stay Consistent with Wear Time

Adhering to your orthodontist's recommended wear schedule helps maintain a steady pace of tooth movement and can reduce overall treatment time.

Practice Good Oral Hygiene

Keeping your teeth and aligners clean is crucial. Brush and floss regularly to prevent any buildup of bacteria that could exacerbate sensitivity.

Use a Desensitizing Toothpaste

Desensitizing toothpaste can help reduce tooth sensitivity by blocking nerve signals that transmit pain. Consider using one recommended by your dentist.

Cold Compress

If you experience gum soreness, applying a cold compress to the affected area can alleviate discomfort.

Ask Your Dentist About Dental Wax

Some dentists recommend dental wax specifically designed for clear aligner wearers. It can be more comfortable and easier to apply than traditional orthodontic wax.

When to Consult Your Dentist

While some level of sensitivity is normal during clear aligner treatment, severe or persistent discomfort may warrant a consultation with your dentist or orthodontist. They can assess your specific situation and determine if any adjustments are needed.


Clear aligners offer a convenient and aesthetically pleasing way to achieve a straighter smile. Although dental sensitivity is a common side effect during treatment, it is usually temporary and manageable with the right approach. By following the tips mentioned above, you can navigate through your clear aligner journey with ease.

Remember, always communicate with your dentist or orthodontist if you experience any concerning issues during your treatment, as their guidance can ensure a successful and comfortable smile transformation. With the right care and support, you'll be well on your way to achieving the smile of your dreams.


How common is dental sensitivity during clear aligner treatment?

Dental sensitivity is a common side effect experienced by many patients undergoing clear aligner treatment. As the aligners gently shift your teeth, it is normal to experience some temporary discomfort, including sensitivity.

What causes dental sensitivity during clear aligner treatment?

During the clear aligner process, your teeth are gradually moved into their desired positions. This movement can cause mild inflammation and pressure on the teeth and surrounding tissues, leading to dental sensitivity.

How can I manage dental sensitivity while wearing clear aligners?

To manage dental sensitivity, you can try using over-the-counter pain relievers or applying a small amount of orthodontic wax to the areas causing discomfort. Additionally, using a desensitizing toothpaste may help alleviate sensitivity during the treatment.

Are there any home remedies to ease dental sensitivity during clear aligner treatment?

Yes, some home remedies can provide relief from dental sensitivity. Rinsing your mouth with a saltwater solution can reduce inflammation and soreness. Avoiding extremely hot or cold foods and drinks can also help minimize sensitivity.

Is dental sensitivity a reason to discontinue clear aligner treatment?

In most cases, dental sensitivity during clear aligner treatment is temporary and should improve as your teeth adjust to the aligners. However, if the sensitivity becomes unbearable or persists for an extended period, it's essential to consult your orthodontist to ensure there are no underlying issues. They can provide guidance and adjustments to make your treatment more comfortable.
