My wife flosses after every meal, sometimes even more. She is prone to getting cavities and has had multiple root canals and an implant as of her mid thirties. She just received news that she needs another root canal. Nearly every visit to the dentist results in one or more new cavities found. I rarely floss because I’m too lazy. Other than one root canal that was the result of me procrastinating on getting an adjacent wisdom tooth extracted, my teeth are pretty much healthy aside from an occasional tiny cavity a decade or so. Seems there isn’t any pattern.
