My dentist was bought out by one of these operations a couple of years ago, and quit after a few months of observing their tactics. I never actually saw her when I went for two 6 months checkups. It was non-stop upsell on water piks, "preventative" procedures, cosmetics. So I switched back when I found out my original dentist had re-opened a private practice.
Stay away from venture capital dentistry operations. Same with veterinary practices -- similar issue with venture capital takeover of our long term vet.
If the operation is owned/financed by venture capital, stay away. Their priority is obviously not health and wellbeing.
