Your first port of call with an NHS dentist complaint is to go through the practice team directly, whether that’s by complaining to the practice manager or the dentist that completed the work. You should follow the official NHS complaints procedure, and you can raise a grievance in writing, via email or by speaking to someone in person.
All NHS complaints should be made within one year of the treatment that you’re complaining about. If you’re concerned about making a formal complaint to the practice directly, you can also contact NHS England instead.
When complaining to your dentist, they should follow the official NHS complaints procedure, with regulations set out by the NHS themselves. The dental practice should be able to provide you with a copy of this complaints procedure – you can also head to the NHS Choices website for more information.
