Thank you for the summary of that documentary @meadow_wind - I'm definitely going to check that out.
My wife has just been diagnosed with Periodontal Disease, and of course, has been scheduled for a root canal procedure.
This article from Unbekoming came at the right time and was a real eye-opener - I've heard it said many a time (or read in different places) that oral health is a window to overall health, but I didn't really grok what that meant. Now I have a better idea and I'm going to keep digging. It seems that Unbekoming has published a book on dental health, 'Drilling for Profit: The Dietary Truth Behind Dental Disease' (for paid subscribers). I'm going to start there.
In the meantime, I've explained the above linked article to my wife and have hopefully convinced her that a good first step is get those troublesome carbohydrates out of her diet. That, and taking the 'Ultimate D3 supplement from DCM.
The cleaning schedule the dentist recommended, I now understand, is an entirely superficial response to what is fundamentally a systemic health issue. It will also keep her returning as a paying customer.
I feel a bit like I'm treading a fine line here. I've been eating a ketogenic / carnivore diet for a number of years, and whilst I've spoken about it a great deal with my wife, she's never felt as though she wanted to give it a go, and I haven't laboured the issue because it's not for me to determine what's good for her. I can only hope that this 'lesson' won't be too painful. I really don't want to see her suffering.
Now, a significant question, given the summary from the documentary above: what about the root canal that is scheduled a week on Saturday?
I'd say have a conversation with her, expressing yourself from a place of care and concern based on what you've learned - but then you just gotta leave it up to her.
