after many years of being at a dental school and being on faculty, i had never learned about those! I had to look it up! (I am specialized in orthodontics) The article I read said that an oral surgeon could remove them. They do not become cancerous but are caused by a stress to the area. They are normal bones covered with tissue. I saw a youtube video mention laser surgery to remove.

From my own experience teaching thousands of dental students and orthodontists, I would find a better oral surgeon to take a look. I have learned you cannot trust everyone with a license to be up on things.

Since they are caused by stress to the area, do you find you are grinding your teeth a lot? a mouth guard might help prevent some of that especially if you are grinding during the night. They can make splints to cover your teeth that are custom if you prefer that.

I don't know your area (I taught in Indiana so that's the oral surgeons I know of) but I think I would check with another one for some advice. Best wishes.
