Never trust a dentist who does not use Windex to clean his instruments
Looks like we just cannot win.
Warning
While dentists use sterilizations, that process is not always 100 percent effective. An article by Elsevier, Inc., brought to light some disturbing facts in 2003. Many instruments used by dentists in the United Kingdom were not all that clean after the sterilization process. Instruments that had been used and then sterilized were scrutinized under a light microscope and scanned with electrons. Of the instruments used in general dentist practices, 76 were contaminated, as were 14 percent of the instruments used by a dental hospital.
