Swelling under the tongue?


Hello doctor, I have a toothache and my face is swollen, my throat is swollen, and the area under my tongue is also swollen.
I was hospitalized and received antibiotics and steroids, which reduced the swelling.
After being discharged, I continued taking antibiotics, but a week later, the area under my tongue swelled up again, although the other areas are not swollen.
I would like to know if continuing the antibiotics will reduce the swelling? What could be the issue?

Hello, it is common to have infections or sublingual salivary gland cysts.
You may continue using antibiotics; however, if symptoms do not improve, it is recommended to continue follow-up visits for medical treatment.

Swelling under the tongue can be a concerning symptom, and it is essential to understand the potential causes and treatment options available. Based on your description, it appears that you have experienced significant swelling in the area beneath your tongue, accompanied by pain in your teeth, facial swelling, and throat swelling. You mentioned that you were hospitalized and treated with antibiotics and steroids, which initially resolved the swelling, but it recurred after you returned home.

The swelling under the tongue could be attributed to several factors, including infections, inflammation, or even allergic reactions. One common cause of swelling in this area is a condition known as sialadenitis, which is an infection of the salivary glands. This can occur when saliva flow is obstructed, leading to a buildup of bacteria and subsequent infection. Another possibility is a mucous cyst, also known as a ranula, which can develop if a salivary duct is blocked or damaged.

Given that you were treated with antibiotics, it is likely that your healthcare provider suspected an infectious cause for your symptoms. Antibiotics can be effective in treating bacterial infections, but if the swelling persists after completing your course of antibiotics, it may indicate that the underlying issue has not been fully addressed. In some cases, a persistent swelling may require further evaluation, including imaging studies or a referral to a specialist, such as an oral surgeon or an ear, nose, and throat (ENT) doctor.

Continuing to take antibiotics without medical supervision is not advisable, especially if the swelling has returned. Overuse of antibiotics can lead to resistance, making future infections harder to treat. It is crucial to follow up with your healthcare provider to discuss your ongoing symptoms. They may recommend additional tests to determine the cause of the swelling and whether further treatment is necessary.

In the meantime, there are some general measures you can take to help manage the swelling and discomfort. Staying hydrated is essential, as it can help maintain saliva flow and potentially reduce the risk of infection. Additionally, practicing good oral hygiene can help prevent further complications. If you experience pain or discomfort, over-the-counter pain relievers may provide temporary relief.

In summary, while antibiotics can be effective in treating infections, their continued use without medical guidance is not recommended, especially if symptoms persist. It is essential to consult with your healthcare provider to determine the underlying cause of the swelling under your tongue and to develop an appropriate treatment plan. Early intervention can help prevent complications and ensure a more favorable outcome.
