As noted, I think the overall focus of this benefit is that it's an interim measure to support families of low and average incomes to access dental benefits. It does consider those situations where expenditures could go beyond $650 in terms of accessing in a year the total $1,300 of benefit over the course of two years. But I think the fundamental point is that there are Canadians in need who aren't accessing services now, and this will enable them to access those dental services.
