I did go to a dentist in India(my home) Dentist said nothing wrong just floss. Then I had moved to berlin and hey I have insurance now for dental check ups.
The first visit resulted in 4 fillings. One filling was bad resulted in root canal. That root canal went bad and the other molar needed root canal.
I took my x rays from first and second dentist to dentist in India, where he told I did not needed those fillings.
At this point I have zero trust in any doctor in Berlin, I get my check ups done in India.
I also did not save any money from my adventures in Berlin, Because every visit resulted in doctor offering a better choice which is not free under insurance and this ended up way costlier than the whole process in my home country.
