This is the primary issue. My dentist who we'd used for 10 years sold without us knowing. Almost all the staff we'd known left and finally the dentist/former owner. I didn't understand what was going on and why the service had gone to shit. Talked to a dentist friend and he suggested it was a PE takeover. I did some research and confirmed that was what happened. Found another privately owned dentist, but it's clear that some laws need to change to protect patients.
