Ball Under Tongue: Understanding Ranulas and When to See a Dentist

If you have discovered a soft, fluid-filled ball under your tongue, you may be dealing with a ranula. A ranula is a cyst that forms when saliva from a damaged or diseased salivary gland fails to drain properly and instead accumulates in surrounding tissues. While often painless, these cysts require professional evaluation to determine the best course of action.

What Causes a Ranula?

Ranulas occur when the sublingual salivary gland is injured or blocked. According to the NCBI, this dysfunction causes saliva to overflow into the tissues beneath the tongue, creating a cyst. These are categorized as simple ranulas (localized under the tongue) or plunging ranulas (extending into the neck). Clinical Note: Unlike simple ranulas, plunging ranulas are more likely to cause visible swelling in the neck region.

Symptoms and Characteristics

Ranulas are typically soft and may appear bluish. Key characteristics include:

• Size: They can reach approximately 2-3 inches in diameter.
• Discomfort: They are usually painless, though large cysts can interfere with swallowing, speech, and chewing.
• Infection: If the cyst becomes infected, you may experience pain and fever. Red Flag: Sudden, rapid increase in size or intense pain may indicate an abscess or secondary infection requiring urgent care.

Treatment Options

Treatment depends on the size and symptoms of the cyst. According to the NCBI and Nationwide Children’s Hospital, options include:

• No Treatment: Usually reserved for smaller ranulas that show minimal symptoms.
• Surgical Removal: According to the NCBI, this typically involves the removal of both the ranula lesion and the affected salivary gland.
• Marsupialization: According to the NCBI, this procedure opens and drains the cyst to allow it to dry out without removing the gland.
• Salivary Gland Ablation: Performed by radiologists, this involves injecting medication into the gland to shrivel the surrounding tissue, as noted by Nationwide Children’s Hospital.

Frequently Asked Questions (FAQ)

How is a ranula diagnosed?

Because other cysts can look similar, an ultrasound is often required to differentiate a ranula from other oral conditions, according to the Western Journal of Emergency Medicine.

Is a ball under my tongue always a ranula?

Not necessarily. While a ranula is a common cause, other issues like blocked ducts (sialolithiasis) or infections can cause swelling when you notice a ball under my tongue. A dentist must perform an exam to confirm the diagnosis.

Can I treat a ranula at home?

No. You should never attempt to drain or pop a cyst at home, as this can lead to severe infection. Always consult a dental professional for safe, effective treatment.

What is the recovery like for surgical treatments?

Recovery varies. Surgical removal may involve stitches and minor scarring, while salivary gland ablation may cause swelling for 1-2 weeks and numbness around the tongue for up to 4 weeks, according to Nationwide Children’s Hospital.
