How can someone find out if they enjoy dental insurance.?

My grandmother says she has dental insurance but is not sure of the signature of the company she is with. Is there a means of access to find out if she has insurance?
Answers:
I assume she is retired. If she is getting medical coverage through her company's retirement plan check beside the company or union she worked for. If she is paying for insurance check her checks. I don't believe medicare covers dental.
Yes. Find her regular insurance card and look through her wallet to see if she has a dental card. She herself, must call the insurance number on the regular insurance and ask.
If you can't find her insurance card in her wallet or the policy within her papers--perhaps check with her DDS to see what they have on record.
Yes, go through the checkbook and see who she compensated the premium to. It's pretty unlikely that she has dental coverage, except through her employer.
