Can anyone help identify this lump in my child's mouth?

[catmg]

He is 3.

We noticed it a couple of weeks ago, it's showing no signs of growing or of going away.

Conscious we will be hard pushed to get a Dr's appointment right now.

Any ideas? It's quite raised, sometimes looks more white than pink.

Does he suck his thumb or lip? Or still have bottles?

No thumb or lip sucking or bottles, and no recent bump or injury that it could be traced back to. It's a bit of a mystery. He's not complaining about it.

Take him to a dentist to be diagnosed.

Looks like a saliva/mucous blister - my child had one and dentist said it was harmless and would only need treatment if it didn’t disappear by itself (which it did).

It looks like a mucocele. I had one and it did go eventually. Was huge at one point.

My daughter had a mucosele and had to have it removed. Was a small op and only 1 stitch. She had it done at 5yrs old. No scar

I think a a mucocele as well. My child had one at that age, it did take months to go away on it's own, but if it is a oucolele, it is harmless.

Thank you all very much for commenting. I have googled your suggestions now and think you're right - a mucocele. I didn't know what to look for previously, and really appreciate your help.
