I recently switched dentist and my new dentist requires that you also have a six monthly appointment with a full-time hygienist also at the same site. I was very skeptical about this but ultimately learnt a lot and my teeth are becoming a lot better for it.

I am not entirely sure if most dentists would be good at delivering hygiene advice to the level of the hygienist (it's a special skill, after all), but I'm also not sure most patients would voluntarily see a hygienist, so it's a tricky problem.
