Similar. I saw a dentist in SoCal when I was visiting my family (I live in the UK) and I was under some misguided impression dentistry was better in the US. Very fancy office, took colour X-rays, then told me I needed all 6 of my fillings redone and a mouth solution to protect my gums. Total amount around 3k.

I decided just to go see my local UK dentist. Shabby office, black and white x-rays. They said all my fillings were perfectly fine and showed me on the X-ray what they look at. They also told me the gum wash (which cost $150) was unnecessary.

That was 6 years ago and I haven’t had any issues with my teeth.
