Answer I have not seen a supplemental policy that would cover the difference. If you did happen to be lucky enough to find such a policy that would, make sure there is not a limitation for a "pre-existing condition" or a waiting period that would need to be satisfied before "major" treatment, like root canals & crowns, is allowed. Doesn't help with your original question, but may be of use if you do find your answer.
Best of luck!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
