A swelling under the tongue, formally known as a sublingual swelling, can be caused by a variety of factors, from minor irritations to serious medical conditions. Understanding the possible causes is crucial for effective diagnosis and treatment. In this article, we delve into the various underlying causes, shedding light on the nuances of each condition and equipping you with the knowledge to make informed decisions about your oral health.
Understanding the Anatomy of the Mouth Floor
Before diving into the causes of a swelling, let’s take a moment to understand the anatomy of the floor of your mouth. The sublingual space, the region under the tongue, is a complex area with numerous structures playing crucial roles in oral health and function. The sublingual glands, responsible for producing saliva, are situated here, along with the lingual frenulum, a thin tissue that connects the tongue to the floor of the mouth.
Common Causes of Swelling Under the Tongue
A swelling under your tongue can be caused by a variety of factors, ranging from minor irritations to serious medical conditions. While the onset of a sublingual swelling can be alarming, understanding the common causes can help you navigate this issue effectively and seek appropriate treatment if required.
1. Oral Trauma:
Simple trauma, such as biting your tongue or accidentally getting a sharp object stuck in your mouth, can cause localized swelling under the tongue. This is typically a short-lived issue, with the swelling subsiding within a few days. However, if the injury is severe or accompanied by persistent pain or bleeding, it’s essential to consult a dentist or oral surgeon. Regular dental check-ups and routine preventative measures like wearing a mouthguard during sports can further reduce the risk of trauma.

2. Infections:
Bacteria, viruses, or fungi can cause infections in the mouth, potentially leading to swelling under your tongue. Some common oral infections include:
- Stomatitis: Characterized by ulcers or sores in the mouth, stomatitis can cause localized swelling, pain, and difficulty swallowing.
- Gingivitis: Inflammation of the gums, gingivitis can also trigger swelling under the tongue, typically along the gum line. Good oral hygiene practices, including regular brushing and flossing, are crucial in preventing this condition.
- Thrush (Candidiasis): An overgrowth of the Candida fungus, thrush often presents with white patches on the tongue and inner cheeks, and can cause swelling, redness, and pain. Thrush is commonly associated with weakened immune systems, antibiotic use, or hormonal changes.
3. Cysts:
Cysts are fluid-filled sacs that can develop in the sublingual space. These are often benign and painless, but larger cysts can obstruct airflow and speech. Several types of cysts can manifest under the tongue, including:
- Ranula: A mucus-filled cyst that commonly originates from a blocked sublingual gland. They can be large and cause significant discomfort, impacting speech and swallowing.
- Dermoid cyst: A cyst containing skin elements, dermoid cysts typically appear as slow-growing masses, often located in the midline of the sublingual space. They are usually harmless but may require surgical removal for aesthetic reasons or if they cause functional issues.
4. Sialadenitis:
Inflammation of the salivary glands, known as sialadenitis, can lead to swelling under the tongue, particularly if it affects the sublingual gland. This condition can be caused by various factors, including bacterial or viral infections, dehydration, or salivary duct obstruction. Symptoms often include pain, swelling, and difficulty swallowing. Treating the underlying cause is essential for managing sialadenitis.
5. Benign Tumors:
While less common, a sublingual swelling can sometimes be due to a benign tumor. These growths are non-cancerous and rarely cause serious health issues. However, they can become large enough to impact speech and breathing, often requiring surgical removal. Common types of benign tumors in this region include:
- Lipoma: A benign tumor composed of fat cells that typically present as soft, movable nodules under the tongue.
- Hemangioma: A non-cancerous growth of blood vessels, hemangiomas often appear as red or purple bumps that can range in size.
- Neurofibroma: A tumor originating from nerve tissue, neurofibromas can cause a variety of symptoms, including pain, numbness, or tingling. These tumors typically require medical attention and may necessitate surgical removal.
6. Allergic Reactions:
Allergic reactions to certain foods, medications, or other substances can trigger swelling in the mouth, including the floor under the tongue. This swelling is usually short-lived, but in some cases, it can be severe and require immediate medical attention. If you suspect an allergic reaction, seek emergency medical care.
7. Medications:
Certain medications, particularly those with anticholinergic properties, can cause dryness of the mouth, leading to potential swelling under the tongue. Consult with your healthcare provider if you’re experiencing any swelling related to medication use.
8. Medical Conditions:
In rarer cases, a swelling under the tongue can be a symptom of underlying medical conditions, such as:
- Hypothyroidism: An underactive thyroid gland can cause swelling in the face and tongue due to fluid retention.
- Sarcoidosis: A chronic inflammatory disease that can affect various organs, including the salivary glands. Sarcoidosis can cause swelling, pain, and difficulty swallowing.
- Leukemia: A type of cancer affecting the blood-forming cells, leukemia can cause swelling in the lymph nodes under the tongue.
Seeking Medical Attention: When to See a Doctor
While many causes of a swelling under the tongue are benign and resolve on their own, prompt medical evaluation is crucial in certain situations. If you experience any of the following, consult a dentist, oral surgeon, or your primary care physician:
- Persistent or severe pain: Pain that doesn’t subside within a few days or that interferes with speaking, chewing, or swallowing.
- Rapidly increasing swelling: A swelling that grows significantly or rapidly, especially if it affects breathing or swallowing.
- Difficulty breathing or swallowing: If you experience any obstruction in your airway or difficulty swallowing solid foods or liquids.
- Bleeding: Any bleeding from the swelling, especially if it’s persistent or heavy.
- Fever: A high temperature, especially if accompanied by other symptoms like swelling or pain, could suggest an infection.
- Changes in the swelling’s appearance: If the swelling changes color, becomes firmer, or develops any unusual bumps or lumps.
Diagnosis and Treatment for Sublingual Swelling
Determining the cause of a sublingual swelling often involves a thorough medical history, physical examination, and potentially some diagnostic tests. A healthcare professional will ask about your symptoms, recent injuries or infections, and any medications you’re currently taking. A physical examination will assess the size, location, and consistency of the swelling, as well as note any other abnormalities in your mouth or throat.
Additional diagnostic tests may include:
- Blood tests: To rule out underlying medical conditions, such as infections or thyroid disorders.
- Imaging tests: X-rays, CT scans, or MRIs can provide detailed images of the sublingual space, helping to identify the cause of the swelling.
- Biopsy: A small sample of tissue from the swelling can be extracted and examined under a microscope to confirm a diagnosis.
Treatment for a sublingual swelling depends on the underlying cause. Here are some common treatment approaches:
- Antibiotics: For bacterial infections, antibiotics can effectively reduce inflammation and pain.
- Antifungal medications: If thrush is the culprit, antifungal medications can help control the fungal overgrowth.
- Anti-inflammatory medications: Over-the-counter pain relievers, like ibuprofen or naproxen, can help manage pain and swelling.
- Steroids: For severe inflammation or allergic reactions, steroids may be prescribed to reduce swelling and discomfort.
- Surgery: Cysts, tumors, or other growths that obstruct airflow, speech, or swallowing may require surgical removal. Surgery may also be necessary for removing infected glands or addressing severe cases of sialadenitis.
- Home remedies: For minor swelling, gargling with warm salt water several times a day can provide temporary relief. Applying a warm compress to the affected area can also help reduce inflammation.
Maintaining Oral Health: Preventing Sublingual Swelling
Good oral hygiene plays a crucial role in preventing a variety of oral health issues, including sublingual swelling. Following these tips can help:
- Brush your teeth twice a day with fluoride toothpaste.
- Floss daily to remove food particles and plaque from between your teeth.
- Use a mouthwash to further reduce bacteria in your mouth.
- Visit your dentist regularly for check-ups and cleanings.
- Drink plenty of water to stay hydrated, particularly during oral infections.
- Avoid smoking and tobacco use, as these habits can increase your risk of gum disease and other oral health problems.
