How to take your temperature

Oral temperature

You'll need an oral thermometer, used in the mouth.

  1. If you've been eating or drinking, wait 30 minutes before you take a temperature by mouth.
  2. Turn on the digital thermometer. Place the thermometer tip under your tongue.
  3. Close your mouth around the thermometer for the recommended amount of time or until the thermometer beep indicates it's done.
  4. Remove the thermometer and read the number.
