I get something similar, not pain but definitely sensations. It was more apparent when I was having dental work done, and the dentist did say to not over exert straight after visiting him because of the increase of blood flow to the gums.

You might just have sensitive gums. There are a couple of places where mine are really sensitive even though there's no disease or teeth issues around them. Because of the other tooth work (implants) I've had a lot of scans and probing of my whole mouth by multiple people so I'm certain there's no problems there - so it's very possible you have no underlying issue either.
