Being a registered dental hygienist for over 42 years I have seen a lot. I can say one thing that changed my practice was the Oral B electric toothbrushes. My patients that went to these had the easiest appointment and were my healthiest patients of my busy days. I would recommend them to anyone who struggles with good hygiene due to improper toothbrush positioning. You literally have to place them on your tooth and slowly move to the next tooth. The Oral B toothbrush has a timer that vibrates every 30 seconds ,  then tells you when you have brushed for 2 minutes.
