Yes it's true - but afaik, dentists can choose to take this route or not as regards charging for children (as from April). The other thing is that NHS charges are going up astronomically - eg., a filling is goimg from something like £11 to about £69, a crown from £60 to almost £200 etc. All in the name of 'improvement'. So if you're due a check-up try and get an appointment before April.
We're with a fab NHS dentist (I've gone to him since I was a child) but now we've moved it's a 40-mile round trip. Dh is with a local dentist but has a private monthly plan - we asked about registering the kids there but were told about this charging thing coming in in April so I'm keeping them at my dentist. Dh's dentist said he was going to do a private dental scheme for children from April at approx. £6 per month per child - so £144 a year for my two.
