How to Treat Invisalign Cutting Tongue: Tips and Tricks for Invisalign Users
Several factors can cause the discomfort of Invisalign aligners cutting into the tongue. Most commonly, these issues arise due to the edges of the aligners not being correctly trimmed or smoothed, resulting in rough or sharp edges that can cause damage to the soft tissues of the mouth. Furthermore, the wearer may be experiencing this problem if the aligners are not fitting properly. In other instances, the issue may be a result of the user’s tongue rubbing against the aligners excessively, particularly if they have recently been fitted and the user is not yet accustomed to them.
This article aims to delve into the root causes of this common problem and provide effective solutions to alleviate the pain and discomfort. Keep reading to discover how you can continue your journey towards a perfect smile without the unnecessary discomfort.

Invisalign Cutting my Tongue Causes
Incorrect Trimming or Smoothing
Invisalign aligners are custom-made to fit the unique structure of each individual’s teeth and gums. However, during the manufacturing process, the edges of the aligners may not be properly trimmed or smoothed, resulting in rough or sharp edges. These edges can easily cut into the soft tissues of the mouth, including the tongue, causing discomfort and even injury.

Improper Fitting
Another reason for Invisalign aligners cutting into the tongue is improper fitting. If the aligners do not fit snugly against the teeth and gums, they can shift and move, creating friction against the tongue. Over time, this friction can lead to cuts and sores. This is why it is crucial to ensure that your aligners are correctly fitted during your orthodontic appointments.
Excessive Rubbing
Finally, excessive rubbing of the tongue against the aligners can also lead to cuts and sores. This is particularly common in new Invisalign users who are not yet accustomed to the feeling of the aligners in their mouths. In their attempts to adjust to the new sensation, they may inadvertently cause their tongues to rub excessively against the aligners, resulting in discomfort or injury.
Are There Any Specific Areas Of The Tongue That Are More Likely To Be Affected?
The tongue’s susceptibility to being cut by Invisalign aligners largely depends on the individual’s oral structure and the way they position their tongue. However, there are a few specific areas that may be more likely to be affected.

Tip of the Tongue
The tip of the tongue is the most agile and sensitive part, often moving around the mouth during speech and eating. Consequently, it may come into contact with the sharp edges of the aligner more frequently, increasing the likelihood of cuts and abrasions.
Sides of the Tongue
The sides of the tongue are also prone to rubbing against the aligners, especially if they are not properly fitted or if the individual has a habit of pressing their tongue against their teeth. This constant friction can lead to discomfort and potential cuts.
Underneath the Tongue
The area underneath the tongue can get irritated or cut by the lower aligners if they protrude or have rough edges. This is less common but still a possibility, particularly if the aligners are poorly designed or if the person has a low-lying tongue.
It’s essential for users to communicate with their orthodontic professional about any discomfort or injury. Remember, well-fitted aligners should not cause pain or cuts. If your Invisalign is cutting your tongue, it might indicate a need for adjustments or potential issues with the way you’re wearing your aligners.
How To Treat Invisalign Cuts On The Tongue
If you are experiencing cuts on your tongue due to your Invisalign aligners, do not despair. There are several steps you can take to treat these injuries and prevent them from recurring. However, it is important to remember that if your injuries are severe or persist despite your efforts, you should consult with your orthodontist or a healthcare professional.
Are There Any Home Remedies That Can Be Used To Treat Tongue Cuts Caused By Invisalign?
Yes, there are several home remedies that can provide relief and promote healing if your tongue has been cut or irritated by your Invisalign aligners. However, it is important to remember that these remedies do not replace professional medical advice, and it’s always prudent to consult with your dentist or orthodontist if you are experiencing persistent discomfort or pain.
Rinse with Warm Salt Water
This is a time-tested remedy for oral sores and cuts. Salt has antiseptic properties that can help clean the wound and reduce inflammation. Dissolve half a teaspoon of salt in a cup of warm water and swish the solution around your mouth for a few seconds before spitting it out. Repeat this several times a day until the cut heals.
Use a Hydrogen Peroxide Solution
Another effective remedy is to rinse with a hydrogen peroxide solution. This can be made by combining equal parts of hydrogen peroxide and water. Be sure not to swallow the solution and rinse your mouth thoroughly with water after use. This can be done twice a day until your tongue feels better.
Apply a Topical Gel
There are several over-the-counter topical gels and ointments designed to soothe oral sores and cuts. These products often contain benzocaine, which provides temporary relief by numbing the area. Follow the instructions on the package for best results.
Stay Hydrated
Keeping your mouth moist can help speed up the healing process. Drinking plenty of water not only keeps you hydrated but can also cleanse the cut and prevent it from drying out and becoming more irritated.
Eat Soft Foods
While your tongue is healing, it may be more comfortable to eat soft foods that don’t require much chewing. Avoid spicy, acidic, and salty foods, which can further irritate a cut tongue.
In wrapping up, the remedies discussed above can indeed offer some short-term comfort. However, it is of utmost importance that the root cause of discomfort is properly addressed. The continuous discomfort or slicing of your tongue by your Invisalign could be an indication of improper fitting. Consequently, it is highly recommended to arrange an appointment with your orthodontist to have the problem rectified.
