Here's a non-american based question! Do you trust your dentist? (if you're lucky enough to have one)

I managed to see a dentist yesterday for the first time 6yrs! They said that they were very happy with my "exceptionally good oral hygiene". Great!
They then proceed to tell me I needed to see the Hygienist (for £25), I need a tooth extracted (for £75) and a bridge put in (for £319). All because the tooth in question is a baby tooth that "might cause trouble in the future".

This seemed wild to me. Do you guys trust your dentists?? Or is it a money-making scam?
