It was used because it worked very well. It gave hery accurate results fairly quickly, for low cost, and they would work very reliably for a very long time.
It's no longer used because then a thermometer is broken or retired, it's considered difficult to dispose of the Mercury safely.
People (even environmental professionals) are very afraid of mercury, even though there is no evidence that it's actually harmful if not inhaled or swallowed.

What is the purpose of the 'kink' in clinical thermometer?
In a normal Mercury thermometer, the mercury moves up and down the capillary as the temperature changes and thus if you removed it form contact with the patient the reading would steadily fall as it cooed. As you need a medical thermometer to give you a reading of the patients temperature even after it has been removed form the patient, you need to stop the mercury shrinking back into the reservoir. The 'kink' does this, it breaks the connection between the mercury in the capillary and the reservoir so the reading given is accurate. On the other hand before it can be used again the mercury in the capillary has to be vigorously shaken back into the reservoir. On a point of interest, clinical mercury thermometers (with the 'kink') are getting very rare because they have been phased out due to concerns regarding mercury poisoning should hey break in use.
