Yes, an electric toothbrush with quadpacer (it times you for 30 sec. in each quadrant) along with religious flossing offers huge benefits.
Anecdote: my sister, even with regular cleanings and an electric toothbrush was having periodontal issues, deep pockets, etc...to the point where her dentist was recommending a complete extraction (ALL of her teeth -- doing a quadrant at a time to let the tissues heal up). Obviously, she was quite alarmed.
I suggested getting a second opinion. And l also shared that my dentist (who is an MD as well as as DDS) had told me a few years prior to take CoQ10 supplements (200-300mg/day) just as a preventative. She said it works at the mitrochondrial level healing "the building blocks of cells".
My sister started taking CoQ10 daily. At her next cleaning, the hygenist and dentist remarked on how much improved my sister's gums were. She then told them about her CoQ10 regime. They told her to keep on doing whatever whe was doing, as the positive results were evident.
All her periodontal issues have since cleared up and she still has all of her teeth.
And she is a CoQ10 believer.
