Swelling Inside Cheek: Causes and Solutions for Dental Issues - Dentistry

Inner cheek


In the past few weeks, I have noticed swelling on the inside of my right cheek (it is not painful and there is no discomfort), which causes me to accidentally bite it while chewing.
I have always had a habit of chewing on the right side.
Could you please explain why the inside of my cheek is swollen and how I can improve this situation? Thank you.

Hello: If there is persistent swelling without known cause that lasts for more than two weeks, and especially if there is a foul-smelling discharge or pus, it is advisable to seek further examination at a medical facility.

More Info


Swelling inside the cheek can be a concerning symptom, especially if it persists over a few weeks. While you mentioned that the swelling is not painful and does not cause discomfort, it is essential to understand the potential causes and appropriate solutions for this dental issue.

Possible Causes of Swelling Inside the Cheek:
1. Dental Abscess: One of the most common causes of swelling in the oral cavity is a dental abscess, which occurs when bacteria infect the tooth or gums, leading to pus accumulation. Even if there is no pain, the abscess can still cause swelling.

2. Gingivitis or Periodontitis: Inflammation of the gums can lead to swelling. If you have gum disease, the tissues around your teeth may become inflamed, causing noticeable swelling in the cheeks.

3. Cyst or Tumor: Although less common, cysts or tumors in the oral cavity can lead to swelling. These growths can be benign or malignant, and their presence may not always be accompanied by pain.

4. Allergic Reaction: Sometimes, an allergic reaction to certain foods, medications, or dental materials can cause localized swelling in the cheeks.

5. Mucosal Lesions: Conditions such as oral lichen planus or other mucosal lesions can cause swelling and changes in the oral tissue.

6. Cheek Biting: If you have a habit of chewing on one side of your mouth, the constant pressure can lead to localized swelling and irritation of the cheek tissue.

Solutions and Recommendations:
1. Maintain Oral Hygiene: Ensure that you are practicing good oral hygiene by brushing twice a day and flossing daily. This can help prevent gum disease and other dental issues that may contribute to swelling.

2. Avoid Chewing on the Affected Side: Since you mentioned that you habitually chew on the right side, try to switch to the left side to avoid further irritation of the swollen area.

3. Warm Salt Water Rinse: Rinsing your mouth with warm salt water can help reduce inflammation and promote healing. Mix about half a teaspoon of salt in a glass of warm water and rinse several times a day.

4. Consult a Dentist: Since the swelling has persisted for several weeks, it is crucial to consult a dentist for a thorough examination. They can perform necessary diagnostic tests, such as X-rays, to determine the underlying cause of the swelling.

5. Monitor for Changes: Keep an eye on the swelling. If it increases in size, becomes painful, or if you notice any other symptoms such as fever, difficulty swallowing, or changes in taste, seek immediate dental care.

6. Consider Dietary Changes: If you suspect that certain foods may be causing an allergic reaction, try to identify and eliminate them from your diet.

7. Avoid Irritants: If you use tobacco or consume alcohol, consider reducing or eliminating these substances, as they can exacerbate oral health issues.

In conclusion, while the swelling inside your cheek may not currently be causing pain or discomfort, it is essential to address it proactively. By maintaining good oral hygiene, avoiding further irritation, and consulting a dental professional, you can ensure that any underlying issues are identified and treated appropriately. Remember, early intervention can prevent more serious complications down the line.
