Well, Llywydd, neither I nor the Member are experts in the science that lies behind safe dental practice. For that, we have to rely on the people who are the experts, and that's why we have a chief dental officer in Wales. I spoke yesterday with Dr Colette Bridgman about the advice she is providing to the profession and how that advice is derived from discussions with leading members of the profession. We have to rely on the people who are employed as the most senior people in their field to give us advice. They keep that advice under regular review. If they feel it is safe to extend the range of activity, they will bring it forward. Dr Bridgman acted on Friday of last week, alongside the other changes that we announced. She lifted the red alert categorisation of dentistry in Wales to allow more procedures to be undertaken more quickly. But we can't proceed other than by relying upon the advice that those people, who are much better placed than me, and, with respect, much better placed than the Member, to understand the science and to give that advice, and that is what we will continue to do.
