I went to the dentist on the weekend to get my teeth imprinted for some invisalign braces. There’s something that really bothers me about dentists and I can’t quite figure out.
Whenever you go to the dentist they take out the nicely packaged tools that tell you they are clean. Then the dentist and his assistant (who is always a female it seems) will take out some nice new gloves to protect their hands. Then they will start to do their thing with your teeth.
They will pry open your mouth with their fingers and drill your teeth until your gums bleed. Then they will wipe the saliva and blood off with their fingers. Then, the thing I don’t understand, they will reach up and adjust the light with their hands that are covered in your saliva.
Do they through all the hygiene precautions and then leave this pothole? Some dentists pit some plastic wrap around the handles which I assume they change for every patient. But what about the dentists without the cover? Do they just put that saliva onto the handles and then transfer it onto the next patient?
How do the dentists keep the light handles clean between each patient without plastic coverings?
(I had to rewrite half this post since it didn’t save the first time for some reason. Not happy)
The view where I wait for my train home everyday.

In between each patient, the dental assistant (female :D) wipes down the dental chair including all the touchpoints, knobs and handles with alcoholic wipes. Patients don’t see this because this occurs before and after you leave.
