Bumps Under the Tongue: Causes and Concerns - Otolaryngology

When it comes to bumps or lumps under the tongue, there are several potential causes that one should consider. The fact that you have noticed these bumps for over two months without pain or itching is a significant detail. Here are some common causes and considerations regarding bumps under the tongue:
1. Lingual Papillae: The most common cause of small bumps under the tongue is the normal anatomy of the tongue itself. The lingual papillae are small bumps that contain taste buds and can sometimes be more prominent in certain individuals. These are typically harmless and do not require treatment.

2. Sublingual Gland Issues: The sublingual glands, which are located under the tongue, can sometimes become swollen or develop cysts. A common condition is a mucous cyst, also known as a ranula, which can appear as a bluish bump. These are usually painless and may not require treatment unless they become bothersome.

3. Oral Candidiasis: A fungal infection, commonly known as thrush, can cause white patches or bumps in the mouth, including under the tongue. This condition is often accompanied by discomfort or a burning sensation, but if you are not experiencing any pain, this may be less likely.

4. Allergic Reactions: Allergies to certain foods, medications, or dental products can cause localized swelling or bumps in the mouth. If you have recently introduced new products or foods into your diet, this could be a potential cause.

5. Infections: Viral infections, such as herpes simplex virus, can lead to the formation of small blisters or sores in the mouth. However, these are typically painful and would likely have resolved by now if they were the cause.

6. Lymphadenopathy: Sometimes, the lymph nodes under the tongue can become enlarged due to infections or other systemic conditions. If you notice any accompanying symptoms like fever, sore throat, or general malaise, this could be a concern.

7. Oral Cancer: While less common, persistent lumps or bumps in the mouth that do not resolve over time should be evaluated by a healthcare professional to rule out malignancy, especially if there are changes in size, color, or texture.

Given that your bumps have been present for over two months without any accompanying symptoms, it is likely that they are benign. However, it is always best to consult with a healthcare professional, such as a dentist or an ear, nose, and throat (ENT) specialist, for a thorough examination. They may perform a physical examination and, if necessary, imaging studies or a biopsy to ensure that there are no underlying issues.

In summary, while many bumps under the tongue can be harmless and part of normal anatomy, any persistent changes should be evaluated by a medical professional. They can provide a definitive diagnosis and recommend any necessary treatment or monitoring. If you notice any changes in the bumps, such as increased size, pain, or other symptoms, it is essential to seek medical advice promptly.
