What is it?
You know what, everything is as deep as a subject, that needs to be studied. Actually, a lot of people don't really know that the problem of toothache is not just on the your teeth, but toothache rather reflects your entire health condition. I am from China, and the medical perspective on any health issue is based on the principle of that, one phenomenon reflects another, and links with another. Like I said, if you really want to know the best way to get rid of a toothache,then you need to know a whole lot of other things, essentially YOURSELF... I recommend you this book, and hope that you can also tell people around you who also have such problem. And knowledge definitely benefits everyone powerfully.. I know I am not offering any quick solutions, but this will prevent your future dental problems.
That would be toothache, or sensitive teeth. See your dentist or get an over the counter medicine.
