Question

Its small. No pain. Annoying, because always playing with it. Gets big and small thruout the day. What is this? I’ve had it for a month now or so. I’m a 35 yr old male.

Answer 

Personally this is a guessing game since I can’t see it. I don’t like the idea that it has been there for a month. At first I thought it was a Tori, which is bone that develops under the tongue, in the palate or even around the teeth over years of time. Since you said it changes in size, that rules out the Tori. It could be a Sialoth, which is a blocked salivary duct. Sometimes they have to be removed for you if it doesn’t pop. Normally those aren’t very big, but if they never get popped or unblocked it could continue to grow. Another possibility is cancer. See a dentist and have it looked at.

Most likely if the size fluctuates it is a blocked saliva duct. It may be a salivary stone, similar to a kidney stone. If it becomes completely blocked, it will only grow. Go see your dentist and show him/her.
