Basically you can get a free examination.
As a patient you are able to also request a scale and polish (s/p or a clean) on the NHS.
Please note that only the initial dental check-up is free. Any treatment arising as a result of the check-up will be subject to normal charges. Only people who have not been to the dentist in more than two years are eligible for a free check-up. To claim a free dental check-up call your dentist and quote "November Check-Up" when booking your appointment.
NHS Guidelines state that you are able to choose whatever dentist you want to go to, so even if you don't live in Barking and Dagenham you can still go to a dentist there.
Probably won't be a huge amount of you that this applies to, but it's worth a shot to those of you who haven't been in a while and live locally.
This is also in the Barking Local Newspaper, a big advert there for it.
If you have any questions regarding NHS treatment etc. please feel free to ask.
