Did the filling pop out?

How did they get there, why did the immune system not flush them out, why did the tubules in that tooth stop doing their job of keeping the tooth resilient? As they clearly have for many years, and still do for dozens of other teeth in the patient? "Bacteria" are always in our mouths, have been ever since mouths first evolved, and from before the moment of birth. Yet usually for many years of youth no such issues occur. Those are the dental questions that mystify me as an amateur observer of the topic! Of course that would imply that a dental issue usually has an undiagnosed/unnoticed medical issue underlying, or plain malnourishment (mineral misbalance etc). Your thoughts?
Sometimes? Given how small bacteria are, isn't this bound to happen every single time after the antibiotics/mouthwash used after/during treatment wear off? Especially taking into view a time frame of multiple decades of life?
I doubt that and would wager the opposite.. again as an interested bystander, not a dental professional. Brushing is clearly a somewhat abrasive action on enamel, especially weakened enamel. As are whitening products and toothpastes. Consequently, the harder, longer or more frequently one brushes, the more enamel is stressed --- in addition to and on top of abrasive and/or acidic food stuffs ingested.

Thanks for replying!

What always amazes me: enamel and dentin don't break down across all teeth equally and uniformly, and not immediately beginning from the first moments those teeth broke out. Lifestyle and nutrition must be at the root, but what bothers me is that we still have no clear-cut answer on prevention. Are acidic foods the major culprit, or abrasion, any carbs or just refined sugar..

Another theory holds that normally tubules are designed to continuously regenerate dentin and enamel (just like bones constantly re-generate themselves) and malnutrition/malabsorption disturb that slowly over time. The approach being, "breakdown of enamel/dentin is normal and unpreventable, failure of regeneration is the real problem to be fixed". Well an interesting topic. Half of my fillings popped out within 6 - 24 months, most of them done in Germany. Every time a filling is done, a bit more of healthy tooth matter needs to be drilled away, so I'm very wary of getting the same fillings done every 1-2 years until most of the tooth will be completely gone another decade or so down the line.

Very interesting, given how infinitesimally small bacteria are, I'm quite curious how we ever managed that impressive feat.
Chewing and wear and tear are 100% guaranteed for everyone on a long enough timeline, so instead of "sometimes" shouldn't it be "more often than not"?

Indeed, so would be cool if the dental profession were to research somewhat deeper into how to help the body regenerate what inevitably gets broken down by real-life. Enamel breakdown may be inevitable, and yet decay isn't --- as every single skeleton (any age well into old age) older than say 100000 years ago (or simply any from today's few remaining "primitive" hunter/gatherer tribes) proves.

That makes sense. Imagine someone eliminates for a few months brushing, acidic foods, abrasive foods, carbs and eats only small swallowable pieces of fresh fatty ruminant meat, indeed swallowing them and never chewing or biting at all (not advisable digestion-wise for plant foods, but absolutely fine for fresh meat, eggs, dairy). What'll be the remaining risk factors for existing or new cavities? Only saliva and medical condition, right? How to take care of saliva and which medical conditions to check for? Would black coffee pose a potential danger to teeth under this setup, you reckon?
I know, and cavities sometimes harden, this suggests enamel is regenerated too, right or wrong?

And what do you think about my earlier question AskTheDent?
