Apparently you can have more than one NHS dentist. Whilst at mine recently, I heard the receptionist tell someone on the phone to register online as they have a waiting list. I know that two of my friends have moved to different NHS dentists as they weren't happy with my particular dentist and a third moved away. None have told my dentist so they are presumably still on their list. I think NHS dentists are required to have a certain number or proportion of their list as NHS. Due to circumstances, I hadn't seen my dentist for 2 years, so could have moved in that time. So, could this be making waiting lists longer than they should be??
