As a side note I don’t agree you are a customer at a nhs dental practice any more than you are a customer of your GP.
The money you pay the practice doesn’t go to the practice, it doesn’t go to the dentist either, the money goes into the nhs pot.
A percentage of this pot of money is then sent to the practices after the practice has submitted relevant paperwork to show their units of activity, usually a month or so after the original form was sent.
The practice will then be paid a fee from the nhs pot and the dentist will be paid a percentage of this fee.
The charges are effectively a tax more than a payment. Although from the patients perspective they have paid for a service as a customer, from a Dentist’s perspective they wont see any of this money at all as it is sent to the nhs. The dentist may see around a third or less of the amount of money you gave to the practice once other charges the dentist incurs have been removed and relevant paperwork submitted to claim a fee.
The charges dentistry accumulate are actually larger than what is spent in nhs dentistry so your charges are actually paying for other areas of the nhs such as medications or Other services.
In 2018 the BDA reported that nhs charges brought in £40million on top of what dentists and practices were paid. Whereas the proportion spent on dentistry is actually shrinking, although charges are rising in April, hence why a lot of dentists are leaving the nhs as it is unsustainable.
Also, should a person complain that they have gum disease and weren’t told as documented in the paperwork, the dentist’s indemnity would not cover them.
The practices will also audit the dentists clinical records and the nhs audits the paperwork. If a dentist is not giving oral hygiene instruction (as evidenced in the electronic paperwork sent to them) the nhs will audit the practice and may impose restrictions on the dentist or practice until best practice is returned.
If the practice finds out the dentist is not conforming to regulations and guidelines they could fire the dentist.
Obviously I can’t tell how this information is given out and maybe your dentist just had a sharp manner but I doubt a dentist is going to place their career, livelihood and reputation on the line.
An nhs dentist takes a 2% pay cut every year to stay in the nhs as evidenced in the nhs statistics. If they could save time by not handing out this information and sending you to the hygienist I’m sure they would as they get paid the same fee regardless of whether you have the clean and take 30 minutes of their time or have only an exam and take 10 minutes.
I work in a related field hence how I know how the charges work and I do feel sorry for the position dentists are put in; they can’t really win either way.
I just see someone doing their job by giving me information which I can then decide to use or ignore similar to my hairdresser telling me which treatments are best for my hair or my GP telling me I am overweight and changed I can make to rectify this.
