Are these dentist good for just regular check ups etc?

The dental nurse came to school so I know DS is ok, but our PHI covers a check up every 6 months no gap with some dentists and small gap with others, but i really dislike our current dentist and want to change... besides her giving me all this rubbish unsolicited advice (i shouldn't let the kids come in my bed at night etc - hard to argue back when you have a mouth full of tools so I had to sit there and listen to her prattle on, but DS for some reason got freaked out, so rather than waiting for him to calm down and open his mouth, she tries to force it open - brilliant way to introduce the dentist to a 3 year old.....she is an idiot!)

I'm trying to work out am I better off finding a family dentist that we can all go to, or taking the kids to a specialist paed one?
