I've just had a dental check up

[Christmasmishap]

I was there about 60 seconds.

Previously they have a poke around with their hooky thing on all the teeth and gums. This time she felt the outside of my jaw, had me move my tongue around a bit then said teeth are all good, see the hygienist. £25 on the NHS for the check up.

Has something changed, is this OK?

No that doesn’t sound right OP.
I'm fortunate to still have an NHS dentist and he has a good old poke around with an assistant taking notes. I usually have a yearly X-ray to see if my impacted wisdom teeth are moving at all.

That doesn't sound right.

Perhaps telephone the dentist and enquire as to what a check up involved (ascertain if it can be sight only, if that's what happened).
And then ask for a refund or rebook for a proper check up.

We had a (slightly) longer check up privately (they recently changed to private only and closed NhS service) - cost £65pp. Was shocked at how little time they looked at anything and when we complained, the practice entered into this 'what did you want us to look at?' 'What have we missed?' kind of chat - like they wouldn't acknowledge a few minutes glance for £65 was ridiculous unless we could specifically say what was clinically the problem - and not being a dentist was a bit difficult. We've not gone back. Standard U.K. dentistry I guess.

every check up I’ve ever had the dentist examines each tooth individually and says things to the dental nurse who makes notes! I also usually leave with a long list of things totalling hundreds of pounds that I need to have done 😅

This is exactly what happened to me at the weekend. I was also like, was that it? Normally they clean them within the £25 but this time nothing.
Someone told me the NHS funding doesn't cover their costs so maybe some dentists are cutting back?
