Invisalign irritating gums

Gum irritation is a common concern experienced by some individuals wearing Invisalign aligners. It can be uncomfortable and, if left unaddressed, may affect the overall treatment experience.

Gum irritation with Invisalign can be caused by various factors, including poor insertion and removal technique, issues with the aligner trays, teeth clenching or grinding, chewing on hard objects, consuming hard or sticky foods, allergies, dry mouth, and so on.

Understanding these factors and implementing appropriate solutions can help alleviate gum irritation during treatment. Here are some possible causes and potential solutions to alleviate the discomfort:

Causes of Invisalign Irritating Gums and Solutions

1. Poor insertion and removal technique

Improper technique when inserting or removing Invisalign aligners can lead to lips and gum irritation. Rough handling or excessive force can cause the aligner edges to rub against your lips and gums, resulting in discomfort and soreness.


To prevent this, it’s important to follow the instructions provided by your Invisalign provider on proper insertion and removal techniques. Gently guide the aligners into place without forcefully snapping them on or off.

2. Bent Invisalign trays

Bent or misshapen Invisalign trays can create pressure points that irritate the gums.


If you notice that your aligners appear bent or distorted, it’s essential to contact your Invisalign provider. They will assess the issue and provide you with replacement aligners to ensure a proper fit and minimize gum irritation.

3. Cracked or broken Invisalign aligners

Cracks or other damage to Invisalign aligners can result in sharp edges that irritate your gums.


Avoid wearing damaged aligners as they may cause further gum irritation and mouth sores. Instead, notify your Invisalign provider immediately. They will guide you on the appropriate steps to take, such as using the previous set of aligners until a replacement is provided.

4. Clenching or grinding your teeth

Teeth clenching or grinding, also known as bruxism, can contribute to gum irritation during Invisalign treatment. The excessive pressure exerted on the aligners and gums can lead to discomfort.


If you suspect that you are clenching or grinding your teeth, it is advisable to discuss this with your dentist or orthodontist. They may recommend a nightguard or other strategies to alleviate the effects of bruxism and reduce gum irritation.

5. Chewing on hard objects

Chewing on hard objects, such as pens, ice cubes, or fingernails, can put unnecessary stress on the aligners and gums, leading to irritation.


It is important to avoid these habits during Invisalign treatment to minimize gum discomfort. Be mindful of what you put in your mouth and refrain from biting down on hard objects.

6. Eating hard or sticky foods

Consuming hard or sticky foods with Invisalgn can also contribute to gum irritation. The pressure exerted while chewing on such foods can cause discomfort and even damage the aligners.


It is advisable to follow the dietary guidelines provided by your Invisalign provider, which typically recommend avoiding hard and sticky foods that can strain the aligners and irritate the gums. Stick to a soft and Invisalign-friendly diet when eating with Invisalign to minimize gum irritation.

7. Dry mouth

Invisalign treatment can sometimes lead to gum swelling and irritation, which may contribute to dry mouth. Dry mouth occurs when there is a decrease in saliva production, leading to discomfort and an increased risk of tooth decay.


Staying hydrated by drinking plenty of water throughout the day is crucial in preventing dry mouth and promoting saliva flow. Additionally, xylitol, a sugar-free sweetener, has shown beneficial properties in treating dry mouth. Dentists and orthodontists often recommend xylitol-containing products, such as Movemints Clear Aligner Mints, to help combat dry mouth while wearing Invisalign aligners.

8. Ill-fitting aligners

Improperly fitting aligners can result in gum irritation. If the aligners are too tight or excessively press against the gums, it can cause discomfort and soreness.


It is important to reach out to your Invisalign provider to evaluate the fit of the aligners. They can make necessary adjustments or provide new aligners to ensure a more comfortable fit and reduce gum irritation.

9. Sharp edges or rough surfaces

Sharp edges or rough surfaces on the aligner trays can irritate the gums. These rough areas can occur during the manufacturing process or due to wear and tear over time.


If you notice any sharp edges, it is advisable to consult your dentist or orthodontist. They can carefully file down the sharp edges (or you can try it yourself) or recommend appropriate solutions to minimize gum irritation, such as using orthodontic dental wax.

10. Poor oral hygiene

Maintaining good oral hygiene is crucial during Invisalign treatment. Inadequate oral hygiene practices can contribute to gum inflammation and irritation.


Make sure to brush your teeth thoroughly, including the gum line, and floss regularly. Your dentist or orthodontist may also recommend specific oral care products or techniques to maintain optimal oral health while wearing Invisalign aligners.

Final Thoughts

Remember, every individual’s experience with Invisalign may vary, and it is essential to communicate any concerns or issues with your dental professional. If you experience persistent gum irritation or discomfort that does not improve with time or home remedies, you should consult your dentist or Invisalign provider. They can evaluate your specific situation, identify the underlying cause of gum irritation, and provide appropriate guidance or adjustments to ensure a more comfortable treatment experience.
