Hard spot(lump)on my lower gum

[Camelia]

Hello.Yesterday I eat something and a small food crumble went under my tongue.I felt there a little movable lump(like a lymph node)at the end of salivary (submandibular )gland(ducts)in the middle on the mouth floor.It might be normal ,but not sure.And then I searched my all gums and mouth and I found this very small hard lump on the inside lower gum.Is not painfull but very hard when I press on it but I don’t know what could be.I am scared a little bit so if you know what can be untill I go to the dentist …Thank you.Last dentist visit was a year ago.

I didn’t mention I had an neck MRI and a base tongue biopsy 11 months ago for a prominent mucosa.Turned out benign,viral squamous cell papilloma.
I wonder if on the neck MRI could have been seen salivary glands,sublingual glands or anything in the mouth?or just the tongue base?

Good day
On the photo provided it might also be only a simple bony exotosis or growth. This is a variation of normal anatomy and nothing to worry about. I would keep an eye on the area. If it enlarges or becomes ulcerated, seek the opinion of an oral surgeon.

Thank you.I’ve been to the dentist yesterday,did an x ray and also palpated it but in rush,she said is nothing ,not to worry about,but still don’t know what actually is the name of it.

Bony or lingual mandibular exostosis. You can google it.

Thank you.So this exostosis can be seen on x-ray?or not really?
