My top 10 reasons for tooth ache occurances:

1. Brushing my Teeth*
2. Chewing Mouth Hygiene Chewing Gum*
3. Brushing my Teeth*
4. Brushing my Teeth*
--- end

* after a long period of not brushing my teeth (as once alarmed by ... you know ... it)


What really helped: Bearing it - brushing the teeth (I'd recommend Elmex Sensitive 'Professional'. It can be used as pain-killer. But only the 'professional' version. Its noted on the package) - and channeling a little bit of ki through your fingers along the cheeks following the "pain strain". Eventually you'll hit a "climax" of sorts. Not by stroking along it, but by 'dotting'. Start where it hurts the most and move on until it ... "fizzles". That however when about to get some sleep.
