I am as skeptical to alternate medicine as the "real" medicine, after finding that it's hard to find studies which weren't funded with an agenda or have issues in their statistical methods or testing procedures etc. Take the following with a dose of salt. - Though now after writing this, it all seems so simple and obvious that I am having second thoughts whether there's anything to talk about here.
I didn't really take good care of my oral hygiene in a long time - I only brushed and used tooth pick when I felt like need to (this clearly wasn't enough) and there wasn't any symptoms, until it was to the point some root canals were needed (atleast according to my dentist). There's fish in the sea with teeth that live 100 years, do they go to plague buildup removal? - question that motivated my research.
Anyway, after the first root canal I've been brushing my teeth and haven't had cavities but the gum condition is close to "irreversible" point where the "pockets" are getting very deep. And with such deep pockets, how do you really clean them I found myself asking. So I started doing some research on what is going on there and after my dentist said "some people don't have these issues" but couldn't really elaborate any further or offer advice beyond the brush/floss regime.
I felt there had to be more to this - why some people don't get tooth decay? From there I discovered the bacteria that somehow had been transmitted to my mouth which use sugar to create the ideal conditions for tooth decay. Then I started asking my dentist, how do I remove that bacteria. And she thought it was impossible. I asked about doing analysis of what's in my mouth in terms of bacteria but apparently mouth bacteria which cause the need to drill belong to some other profession.
As I'm feeling the pressure of having to do something before those pockets get beyond 4 mm deep which is supposedly "borderline" on whether they can heal, I found what I was looking for - other people, even professionals in it, are questioning the "industry practise".
Now I am sure the dentist profession has gained a lot of useful knowledge in the areas of surgery and such operations, but it's time that the focus moves beyond just drilling holes when you go to a dentist - given there's some research suggesting that there could be ways to have results that don't end up in filling or root canals while getting same result. Today there's more dental clinics than any other services where I live (more than grocery stores or bars within same area), which suggest room for improvement.
You can find the book by searching for: Money by the Mouthful (and another one is: Become Dentally Self Sufficient)
The summary of what this doctor is saying is that all you need is salt water irrigation - no wonder those fish in the sea don't need frequent dentist visits or toothpaste and no wonder it's not advertised - where's the money in that. I've also heard of a story where someone started developing dental issues only after their first dental check, before coming across this book. Similar things are mentioned in these materials and makes sense to me - when the dentist examines the teeth, they don't clean the sharp metal instruments between going from teeth to teeth. If you have/acquire Mutans bacteria and eat anything with sucrose after this poking around with the sharp tools before the poked surface restored itself and fail to do intensive cleaning until the area heals, the Mutans can now create its glue like substance inside that crack allowing a cavity to begin forming.
I am going to try the saline water irrigation suggested to see if my current 4 mm pockets will heal - unfortunately I already have few teeth that will likely need surgical operations eventually. I'm currently doing toothpaste+brushing+flossing - but brush nor the floss reach in few places which have got quite bad. I'm also avoiding everything with sucrose as it enables the adherence of the acid producing bacteria. That really is the key problem here - if I didn't have the bacteria then sucrose would be like any other sugar and the management wouldn't be as much of a chore.
