Do you envy sharks? Sharks have a great advantage over human beings. Their teeth grow not only twice as it is in the nature of human beings. At every time they need new teeth they get some. What a good thing! No longer any toothache, never the necessity to repair teeth!
But this would be a bad thing for dentists. In this case nobody would need their help when having a cavity in a back tooth. There would be no need to eliminate dental plaque, to receive removable or fixed prosthodontics or dental implants. This would be really a fatal matter. But people are not sharks. They have not the luck of boundless prosthodontics without any help. So they need dentists, and dentists are happy to have their work.
Where does the dentist live? Formerly a dentist in a country with low salaries could offer his service to people who came from abroad, perhaps from Germany. Some German people look for cost-saving prosthodontics or tooth implants. In Germany this is called Zahnersatz and Zahnimplantate. So if the dentist would know the German terms and definitions of Zahnersatz and Zahnimplantate he could offer his service to Germans. If he speaks some German he will get a lot of German visitors, who look for a low -priced Zahnersatz and reasonable Zahnimplantate.
Surely this is sometimes a difficult way to make a good and profitable deal with Zahnersatz or Zahnimplantate. But this may not at all be so impossible as it seems to be. Many dentists from countries all over the world had their trainig in dentistry in good old Germany. So they sholud speak an excellent German and should never have problems to understand German visitors, who look for Zahnersatz or Zahnimplantate.
Why do German people go abroad for Zahnersatz or Zahnimplantate? These are the people who have to pay for it by themselves. In this case it can be advantageous to look for low-prized Zahnersatz and Zahnimplantate which should be of high quality. Exactly these conditions they could find in countries which have good dentists and dental laboratory technicians who have not enough customers from their own country. These people appreciate an additional business with customers from abroad. And if they do a good work German people will go home and tell it to their friends, and so the next customer will come soon for a high quality prosthodontics or dental implant.
