Swelling in the upper oral cavity?


This morning, while having breakfast, a lump suddenly appeared on the upper inner side of my mouth as shown in the image http://imgur.com/z44d3XO.
It gradually diminished, but it reappeared during lunch and dinner.
Although it does not affect my daily activities and is not painful, it is quite bothersome.

The above situation may indicate inflammation of the minor salivary glands within the oral mucosa.
It is recommended to consult a dentist for further examination.

More Info


Sudden oral bumps can be concerning, especially when they appear unexpectedly and cause discomfort or anxiety. Based on the information provided, there are several potential causes for the sudden appearance of bumps in the oral cavity, particularly on the upper inner cheek area.
1. Mucoceles: One common cause of bumps in the mouth is a mucocele, which is a cyst that forms when a salivary gland is blocked or damaged. Mucoceles are typically painless and can appear suddenly. They may fluctuate in size and can disappear on their own, but they can also recur.

2. Oral Canker Sores: Another possibility is the development of canker sores, which are small, painful ulcers that can occur on the oral mucosa. While they usually cause pain, some can be asymptomatic initially. Stress, hormonal changes, or certain foods can trigger their formation.

3. Infections: Viral infections, such as herpes simplex virus, can lead to the formation of vesicles or bumps in the mouth. These may be accompanied by other symptoms like fever or malaise. If the bumps are recurrent and associated with other systemic symptoms, it may be worth considering a viral etiology.

4. Allergic Reactions: Allergies to certain foods, medications, or oral hygiene products can also manifest as bumps or swelling in the mouth. If you have recently introduced a new food or product, this could be a potential cause.

5. Fibromas or Other Growths: Sometimes, benign growths such as fibromas can develop in the oral cavity due to chronic irritation or trauma. These growths are usually painless and may require a biopsy if they persist or change in appearance.

6. Oral Lichen Planus: This is a chronic inflammatory condition that can cause white patches or bumps in the mouth. It may be associated with stress or other underlying health issues.

Given that the bumps you are experiencing seem to resolve and then reappear, it is essential to monitor their behavior. If they continue to recur, change in size, or become painful, it is advisable to consult with a dentist or an oral specialist. They may recommend diagnostic tests, such as a biopsy or imaging studies, to rule out any serious conditions.

In the meantime, maintaining good oral hygiene is crucial. Rinse your mouth with warm salt water to help soothe any irritation and prevent infection. Avoiding spicy or acidic foods may also help reduce discomfort.

If you notice any additional symptoms, such as fever, difficulty swallowing, or persistent pain, seek medical attention promptly. Understanding the underlying cause of these oral bumps is essential for effective management and peace of mind.
