I can’t see many benefits of going private for basic preventative treatment – check ups, x rays and scale and polish, although perhaps it will be a lot easier to get an appointment that suits your diary by going private.
I am no lover of dentists after having very poor and unprofessional treatment as a child. So for me trust in my dentist counts for everything.
I have recently just joined a new practice after a long absence and was quite surprised to see the apparent variation in private costs even with a 1 mile radius of where I live. NHS is not really an option for mw given where I live.
