whats an elimination period in insurance, particularly how might it work in dental insurance?

I'm taking another jab at this for a good answer, prefer answers from insurance professionals but all answers welcome

Well , i see it has been 8 hrs. and no answer. I don't know answer, but I believe if you call the dentist's office and ask to speak to the insurance specialist, you will get the answer. Never saw an office without an insurance specialist, and they are very knowledgable.
