This! We went to a pediatric dentist with my kid on Monday, with a referral from another dentist, both private. After small talk, their first proper question was: "Do you have insurance?". Before I could respond, my wife responded affirmatively. Insurance here in Ireland means private insurance. After an x-ray, we were presented with a menu of treatment options ranging from around €2k to €5k.
Later I requested the clinic to share the x-ray with me and consulted with another pediatric dentist from another EU country. His assessment was completely different, and recommended very minimal intervention.
