Issues Under the Tongue


Hello, doctor.
Recently, I suddenly developed a small red bump under my tongue.
At first, I thought it was a sore, but when I touched it, it didn't hurt.
Now it has grown into a red lump.
What should I do?

Hello: Based on your description, there is a well-defined and discolored lesion in the sublingual mucosa that has appeared in a short period of time.
If you have a history of smoking and betel nut chewing, it is advisable to promptly visit the oral surgery department of a hospital for a biopsy to clarify the cause.
Thank you!

More Info


When it comes to the appearance of red bumps under the tongue, it can be concerning, especially if they change in size or appearance. The first step in addressing this issue is to understand the potential causes and appropriate treatment options.

Red bumps under the tongue can arise from various conditions, including:
1. Irritation or Trauma: Sometimes, accidental bites or irritation from dental appliances can lead to localized swelling or bumps. If the bump is small and painless, it might just be a result of minor trauma.

2. Canker Sores: These are small, painful ulcers that can appear on the tongue or inside the mouth. They are usually round with a white or yellow center and a red halo. While they typically heal on their own, they can be uncomfortable.

3. Mucocele: A mucocele is a cyst that forms when a salivary gland is blocked or damaged. These are usually painless and can appear as a soft, fluid-filled bump. They often resolve on their own but may require surgical removal if they persist.

4. Lingual Papillitis: This condition involves inflammation of the taste buds, which can cause red bumps on the tongue. It is often temporary and resolves without treatment.

5. Infections: Viral infections, such as herpes simplex, can cause blisters or sores under the tongue. Fungal infections like oral thrush can also present with red lesions.

6. Allergic Reactions: Allergies to certain foods, medications, or dental products can lead to swelling and bumps in the oral cavity.

7. Oral Cancer: Although less common, persistent bumps that do not heal or change in appearance should be evaluated by a healthcare professional to rule out malignancy.

Given that your bump has grown into a red, fleshy mass, it is essential to seek medical evaluation. Here are some steps you can take:
- Consult a Healthcare Provider: A dentist or an oral surgeon can provide a thorough examination. They may perform a biopsy if necessary to determine the nature of the bump.

- Monitor Symptoms: Keep track of any changes in size, color, or pain associated with the bump. Note any additional symptoms, such as difficulty swallowing, changes in taste, or persistent soreness.

- Maintain Oral Hygiene: Good oral hygiene can help prevent infections and further irritation. Brush your teeth and tongue gently and use an antibacterial mouthwash.

- Avoid Irritants: If you suspect that certain foods or dental products may be causing irritation, try to avoid them until you can consult with a healthcare provider.

- Follow-Up: If the bump does not resolve or worsens, follow up with your healthcare provider for further evaluation and management.

In summary, while many bumps under the tongue are benign and may resolve on their own, it is crucial to have any persistent or changing lesions evaluated by a healthcare professional. Early diagnosis and treatment can help address any underlying issues and provide peace of mind.
