I just found a hole in my top tooth in the far back tooth. It hurts when I shake my head or tap the top part of my head or even touching my face. It does not hurt to eat with this tooth but it does to jump or bend over. It feels like there is something in it. Please help me does any one know what this is? I am unemployed and Have no Insurance I'm falling apart. Please Help me

It sounds like you have a major cavity :/ I can't even begin to tell you how many cavities I've had so I know how painful and uncomfortable it can be, but you need to find a way to make an appointment to get it looked at because I ignored mine and it ended up turning into a root canel and had to be replaced (which is exspensive). If you get it looked at now, it will save you a lot more money than waiting until it's too late.
