Does medicaid or medicare cover my dental expenses?

I'm 20 and I live in California. I've always had a medicaid card because my parents don't work. Do I stop having insurance after I turn 21? I'm still a college student. I want to go to the dentist one more time before I turn 21. Will I still be covered?

You should be covered, but call up the dental office and tell them to run an eligibility report.
