In some cases no but in some case yes. For example does the trasport of fuel to the homes create wealth? Does the getting this fuel from the ground create wealth (it is vertical transport)? Does the production of syntetic fuel create wealth? I would say in each case it does. Does the manufacturing the artificial teeth create wealth? Yes. Does the fixing the natural teeth so they do not need to be replaced, create wealth? Yes.
What is wealth? Isn't it some accumulation of value? If so, the services if they increase or preserve the value they produces wealth too. Also I think it is hard to draw the line between manufacturing and services.
