I suffered terribly with bad teeth, calcium deficiency, teeth pressing forward breaking, extractions ect,so with that in mind
when we hurt ourselves the first thing we do is to touch or rub the area that we think is damaged,bare with me you will see it's worth it !!.I studied SHIATSU or finger pressure it can be applied
in a massage or by simply touching using fingers or hands. OK
now to your tooth ache, when you cut your finger your bodies natural reaction is to send white cells to repair the damage,the pressure of this is why we bleed.With tooth ache the same thing but the cells have nowhere to go, hence the throbbing you are feeling now,put your finger where the throbbing sensation is, you will feel it like a pulse. If the ache is on your lower jaw the throbbing is coming from the veins running under your jaw, a finger length from your chin back,press and the pain will go,if on top jaw just in front of your ear, this is only temporary relief you must get to a dentist,be-ware although shiatsu is good at releiving pain please read up on it.
