What Is a Ranula? The Bluish Cyst Under Your Tongue That Can Become a Problem

There is a bluish swelling under your tongue. Your dentist called it a ranula — a cyst that forms when a salivary gland gets blocked. Here is what it is, whether it needs treatment, and what happens if it does.

There is a bluish swelling under your tongue. Your dentist called it a ranula — and you probably have questions.

A ranula is a cyst that forms when one of your salivary glands — usually the sublingual gland — gets blocked or damaged. Instead of saliva flowing into your mouth, it collects under the skin, creating a smooth, blue-tinged bubble. It looks more alarming than it usually is.


How do you know you have one?

You might notice a soft, squishy lump under your tongue or along the floor of your mouth. It can be blue, translucent, or slightly pink. It does not usually hurt, but if it gets infected it may become tender or swollen.

Some people first spot it after eating, when the gland has been more active. Others only find out during a routine dental check-up.


Does it need treatment?

Small ranulas that do not bother you may simply be monitored. But a larger one can interfere with eating, speaking, or swallowing. In some cases it can grow or become infected.

If treatment is needed, the options include draining the cyst, removing the affected salivary gland, or a combination of both. Your dentist or oral surgeon will recommend the approach based on the size and location of the cyst.


What happens if it is left alone?

An untreated ranula can slowly increase in size. It may also rupture on its own, which can be painful and lead to recurring swelling. Getting it assessed early means simpler treatment and a better outcome.

If you have noticed a lump under your tongue, mention it at your next visit. And if it is changing, growing, or making eating uncomfortable, do not wait — book an appointment and get it checked.
