As with all of my Medicare Advantage Plans, you should be eligible for dental benefits. Benefits always include preventive care which includes $0 copay for exams, cleanings, x-rays, and fluoride.
Because of your DUAL status, with an Advantage Plan, you should be eligible for money to cover comprehensive dental care. Plans vary and the amount of money available for your care can vary.
There are rules that prevent me from discussing plans in detail on my website. We really need to talk to determine what is best for you. Medicare does require proof that we have permission to talk to each other. They call that a Scope of Appointment which we can discuss when we talk.
