Yes, Smile Generation tried to rip me off, got a second opinion and stopped just in time. My company choice one year was supposedly the premium dental for low price, turned out to be all companies with “Smile” in the name. Checked them out, all rip-offs. Went to one just for a free exam just to tell them off, then had to wait a year to get coverage with a real dentist.
All the dentists in our medicare plan are like that - part of some group. They also all seem to be foreigners. We pay extra to have our own private dental insurance, so we can choose our own dentists.
