Pretty much all my teeth crumbled away after years on a high-carb diet with gluten and sugar (and, to be fair, taking drugs), and I had frequent abscesses. Eventually some years ago I had all my top teeth out and all the bottom except for 7 at the front. About then I switched to paleo - grain free, low fructose, lots of animal food and fat.
Even though my remaining teeth are full of big cavities, they have not broken, chipped, become infected or acquired any new holes since I changed my diet (and, to be fair, gave up drugs). At this rate, they may last as long as I do.
I wish I'd known about this sooner!

Interesting! What kind of toothpaste do you use? I haven't had a filling in 20 years. I credit our straight-from-the-ground hard water that I've been enjoying since moving here. But if I use any products with sorbitol -- which is most toothpastes and flavored mouthwashes -- I can kick up a gum problem in a couple of locations. Apparently, bacteria can adapt to using sorbitol.

Yeah, I used to be baffled that gingivitis and miscarriage are positively correlated. The bast I could figure was lifestyle factors independantly impacting both. But the systemic inflammation thing it the kicker; your body isn't going to let you risk something like gestation with rot in the floor joists.
I've had a pocket behind one tooth for a year that never gets better or worse. I tried oil pulling (inconsistently - didn't like it) but abandoned the Sonicare plan due to costs where I am, but I may revisit that idea when I'm next in NAm because my HDL reading is kicking my ass.

I'm in the middle of reading Nutrition and Physical Degeneration by Weston Price. It's a very good read and supports your N=1 experiment.

I have had very similar results. Paleo 2 years and 8 months now. No bleeding gums ever at my dental visits. I never floss, only Sonicare and toothpicks once in a while. My dentist was happy too.

I've been on the paleo diet for a few months now, not for anything serious but just to become more energized and healthy in general. While trying out this new diet It never occurred to me the positive effects it would have on my teeth and gum health. The tissue around my teeth is a much healthier pink and whenever I flush or brush, I don't see one bit of blood, nothing. I am actually still getting used to it! This diet definitely has it's benefits. To anyone just trying it out, make sure to have a good list of paleo recipes. It helps in the long run.

My hygienist has said the same things to both me and my wife for the past 2 years. She makes these unprompted "Wow you are really looking good" remarks about my teeth and gums and has asked what changes we made.

This has been a consistent thing ever since we started a lower carb Paleo diet about 2 years ago.

this very much backs the idea explored in good calories bad calories that poor dental health is followed roughly 10-20 years later by poor health in heart disease/cardiovascular disease and cancer development too.

i imagine this was covered by other writers too, weston a price springs to mind, but i first read it there.

i cannot remember where, but i do recall reading a theory that the body may "allow" a cancer to develop as a means to deal with excess blood sugar as a final ditch effort before going full blown diabetes.
this would mean the body does not die so fast in the short term, due to the toxic glucose being consumed by the cancerous cell(s) protecting the rest of the organism.

of course the longterm implications are pretty poor, but the body tends to focus on short term (keep alive long enough to procreate) rather than long term (live to be 100) anyway.

I really liked the very clean feeling I got with a Sonicare toothbrush, but never experienced any improvement in my 3, 4, & 5 mm gum pockets when I used it, despite regular 3 x year hygienist cleanings, brushing 2-3x day, and a low starch/low sugar/GF/paleo diet. By accident on an overseas trip without my Sonicare I discovered my Sonicare toothbrush was probably the source of the nighttime tinnitus I'd been experiencing for several years, so I went back to using a manual toothbrush. I resumed and stopped using the Sonicare brush several times to test that the tinnitus was definitely caused by its use). YMMV.

Last year while undergoing orthodontic treatment (at age 49) to broaden my narrow and slightly crowded dental arches and improve my bite (mild malocclusion was the likely cause of abfractions on some of my teeth due to force loads), I began using a sulcabrush regularly along my gumline to target areas where a regular toothbrush couldn't easily reach with the wires and brackets in the way - wow, what a difference that little brush head made! The braces have been off for 7 months now and I continue to use the sulcabrush along the gumline - at my recent dental hygiene visit my pocket measurements were reduced (though I'm hoping there will be further improvement next visit), the pronounced gumline sensitivity during scaling was greatly reduced, and my gums no longer bleed at all when flossing (and oh, do I love to floss now that my teeth no longer feel crammed together, and I no longer am restricted to the thinne$t and $lipperie$t name-brand flo$$e$).
