A ranula is a cyst under the tongue.

It happens when a saliva gland leaks saliva into the surrounding tissue, forming a cyst.

A ranula can appear as a clear bump under the tongue or small bubble under the tongue.

Ranulas are not painful, so they often go unnoticed until theyre big enough to cause discomfort.

Theyre often from bites or other trauma.

The same is true for a ranula.

In addition, most ranulas will reappear even if you pop or drain them.

A healthcare provider needs to address the leaking gland to get to stop the ranula from reforming.

In addition, your healthcare provider will want to examine the ranula carefully using ultrasound and other imaging.

Aftercare and Oral Hygiene

Your healthcare provider will instruct you on aftercare.

After surgery, you may have to avoid certain foods or beverages.

For example, wear a mouth guard during sports and venture to avoid biting your lower lip.

Ranulas should never be popped or drained at home.

Doing so can cause infection and they will likely recur.
