It may still take us some time to reach that goal, but the good news is that we have an effective solution available right now: keeping good oral hygiene is known to prevent both caries and gum disease, and takes less than 10 minutes a day for the average person. If you need more information, we recently developed a free website to get you started: https://lifelongsmiles.hk/
My wife seems to be basically immune to cavities; I get them easily. I brush very carefully; she brushes only quickly. Our diets are the same — if anything she probably gets more sugar. We have the same water source. Etc. Clearly there’s a lot more to this than what you’re claiming. Unless you’d propose that all of my current problems are due to conditions while I was child or similar.
I skipped the dentist for 18 years, and during the earlier part of that span I had pretty sparse dental habits. I went in expecting the worst, but I had 1 cavity, and it was shallow enough to be drilled no novocaine. Nowadays I just brush once a day.
Thank you for letting me brag, because the other parts of my body, like heart and lungs, are total shit.
