My recent experience with this:

In 2019, I went to the dentist for the first time in over 15 years, and everything was fine.
Then the «pandemic» hit, and shortly after, in mid-2025, I discovered a large cavity in my lower right wisdom tooth (I’m right-handed). At the dentist’s office, several other smaller cavities were found in various places.

Was the COVID-19 pandemic the cause of various conflicts involving biting? Emotionally, that would make perfect sense, since we could hardly protect ourselves against the arbitrary restrictions. But why on the left side as well? I had conflicts involving biting with society/the government/…—but nothing with my mother or children.

Or was acid or bacteria the cause? Six months earlier, I had started drinking mostly juice instead of water as an experiment. But then why weren’t the most hard-to-reach areas affected? I had never used interdental brushes. The dentist cleared and cleaned the interdental spaces for the first time—but in the areas where my toothbrush had essentially never reached, and where the bacterial situation is certainly by far the worst, I had no issues.
