Oral issues


I have a small swelling on the upper left side of my mouth near the throat that sometimes occurs when I eat.
It is not painful and usually disappears about an hour after eating.
What could be the cause of this? Thank you.

It may be sebaceous glands or small salivary glands within the oral mucosa.
It is recommended to consult a dentist for further examination.

More Info


Temporary swelling in the mouth, particularly in the area near the throat, can be concerning, especially if it occurs intermittently and resolves on its own. There are several potential causes for this phenomenon, and understanding them can help alleviate your worries and guide you toward appropriate solutions.


Possible Causes of Temporary Swelling
1. Allergic Reactions: One of the most common reasons for localized swelling in the mouth is an allergic reaction to certain foods. Common allergens include nuts, shellfish, and certain fruits. If you notice that the swelling occurs after consuming specific foods, it may be worth considering an allergy.

2. Irritation or Injury: Sometimes, minor injuries to the oral mucosa can cause localized swelling. This could occur from biting the inside of your cheek or tongue, or from consuming hot or spicy foods that irritate the tissue.

3. Salivary Gland Issues: The swelling could be related to the salivary glands, particularly if it occurs while eating. Conditions such as sialadenitis (inflammation of the salivary glands) or salivary stones can cause temporary swelling. If the swelling is associated with a dry mouth or difficulty swallowing, this could be a sign of a salivary gland issue.

4. Infections: Although less common, infections in the mouth or throat can lead to localized swelling. This could be due to viral infections, such as herpes simplex, or bacterial infections, which may require medical attention.

5. Cysts or Growths: Occasionally, benign cysts or growths can form in the mouth and cause temporary swelling. These are usually painless and may fluctuate in size.


Solutions and Recommendations
1. Observation: If the swelling is not accompanied by pain, difficulty swallowing, or other concerning symptoms, it may be reasonable to monitor the situation. Keeping a food diary to track what you eat when the swelling occurs can help identify potential triggers.

2. Avoid Known Irritants: If you suspect that certain foods or substances are causing the swelling, try to avoid them. This includes spicy foods, acidic foods, or anything that you have previously reacted to.

3. Hydration: Staying well-hydrated can help maintain saliva production and may alleviate some swelling related to dry mouth or salivary gland issues.

4. Consult a Healthcare Professional: If the swelling persists, increases in size, or is accompanied by other symptoms such as pain, fever, or difficulty swallowing, it is important to consult a healthcare professional. An ENT (Ear, Nose, and Throat) specialist or a dentist can provide a thorough examination and may recommend imaging studies or allergy testing if necessary.

5. Medication: If allergies are suspected, over-the-counter antihistamines may help reduce swelling and discomfort. However, it is best to consult with a healthcare provider before starting any medication.


Conclusion
In summary, while temporary swelling in the mouth can be benign and self-limiting, it is essential to pay attention to accompanying symptoms and potential triggers. Keeping track of your diet and any other changes in your health can provide valuable information to your healthcare provider. If the issue persists or worsens, seeking medical advice is crucial to rule out any underlying conditions and to receive appropriate treatment.
