Dr accidentally put thermometer in my mouth without plastic cover (he noticed afterwards) because the one he meant to put fell off, can i get sick?

Uncapped thermometer: Highly unlikely, bugs as HIV, hep C, herpes ( cold sores) die quickly when exposed to dry air Likely,would have died in the interim between patients. On top of that it is likely it was clean before it was put in your mouth because the cap was on for others, and the third layer is our immune system is efficient against bacteria, they are all around us from sneezes ,cough. Do not worry.
