I have this a lot and have had it for some time. usually it only lasts for 1 to 2 days and starts up because I floss or brush too hard, or if I've had a recent dental appointment where they've scraped and cleaned the teeth. I think it may in fact be gum disease. Pretty sure that's what mine is, but if you're gums don't bleed then you may just have sensitive teeth. Some things that can help are rinsing with baking soda or warm salt water to lessen the aggravation and I've heard some allergy medicines work too. The way I get rid of it though, is by not touching, pressing on, or aggravating the teeth at all. I know it may be hard considering how incredibly maddening it gets, but if you push on them or play with them they'll continue to itch and tingle. Don't touch them for a day or so and it'll probably go away on its own.
