Which dental office should I chose when I have not had a dental appointment in a while? Worried about private equity

My dentist I went to for years, my insurance doesn’t cover anymore. I found out I need 2 cavities filled but I had work so I didn’t do it that day. Then I got a bill saying they’re no longer in network.

There’s a chain which my insurance covers. I went once to get the 2 fillings and they told me I have 8 plus I needed a root canal. Then they had people come in and tell me if I buy a subscription i can get a certain discount for exams and cleanings plus fillings. I got so scared by it I didn’t go back. There must’ve been 3 people who tried to convince me and show me their phone calculator with the price I’d pay.

I found another dentist it’s a new office but only one. They take my insurance but the office is super beautiful and trendy looking. I’m not hating on that it’s just the other chains around me especially the one with bad reviews has that kinda modern trendy look as well. Their site talks about care credit or signing up for something if you can’t afford it? It looks like a med spa almost and the reviews are good but the one review about a filling the person said it fell out. 4 dentists and a surgeon work here

There’s an older dentist who’s office is just him and an endo with really good reviews and loyal patients even in my local facebook group they recommend him but there’s a few reviews about people getting told they need a lot of work done? Like a root canal or someone just writing they had a bad experience. I think this guy is older and been in the game. The other place is younger dentists. Not that it matters just wondering what do I do
