It's, of course, incredibly difficult to ensure that the Government can plan efficiently, in terms of capacity for dental care in Wales, if the Government or health boards don't know how many people are waiting for an NHS appointment. I know you would agree with that position, Minister. It's also unacceptable, of course, that people, once they're on a waiting list, could be waiting up to 26 months before getting an appointment as well. So, I wonder, Minister, will you explore the options for a centralised waiting list for Wales? I appreciate that would take some time to put in place, so, as an interim measure, would you also explore ensuring that every health board establishes a centralised waiting list for its area? And if you do agree with that, when do you think that could be in place?
