There is only one thing I can think of that would have facilitated this improvement. I switched to the Oral B Pulsar about a year ago. It is a battery powered tooth brush that costs about $6 in the store but it has done better than the expensive rotary and sonic bushes that I have purchased in the past.
I was so pleased that I bought two more when I went to the store, at this rate I might get to hold off on those dentures for a few more decades.
