Thanks for the response and advice, much appreciated.
Yes indeed that is interesting, but I do have a hunch about it. The teeth are connected to the skull and jaw, but there can be a slight movement in their sockets. Also the nerves around this area tend to exaggerate anything tiny happening, like a grain of sand in your shoe is nothing, but if in your eye or between your teeth.. So I think it's both, a little off bite and exaggerated sensation on top.
