Before going low carb my dental hygienist suggested that I should consider quarterly teeth cleanings. My plaque and tarter buildup was that bad. My gums were always bleeding, sore, and puffy after a cleaning. I had regular cavities throughout my life. Two of my teeth eventually broke, requiring crowns to fix them up. For me visiting the dentists was not one of my favorite things. I brush. I floss often enough. Yet my mouth was still an expensive disaster.

Since going low carb in 2014... no cavities. My gums have firmed up. My hygienist marvels about how my gums don't bleed at all even after she performs a vigorous flossing. These days my plaque and tarter buildup is such that I only need a cleaning once a year. Both my dentist and hygienist have commented several times about my improved dental health. My response is something like "You dentists always say that sugar promotes cavities. You say to cut back on sugar. I actually do that and this is the result."

YMMV - but LCHF gives me a happy, healthy mouth. I've saved a ton on dental expenses over the past few years. It's a good thing, too. My dentist dropped out of all healthcare networks. Anything I have done now costs big bucks - even a cleaning.
