Armpit temperatures are usually the least accurate. Rectal temperatures provide the best readings for infants, especially those 3 months or younger, as well as children up to age 3. For older children and adults, oral readings are usually accurate — as long as the mouth is closed while the thermometer is in place.
If you plan to use a digital thermometer to take both oral and rectal temperatures, you’ll need to get two digital thermometers and label one for oral use and one for rectal use. Don’t use the same thermometer in both places.(source)

What kind of thermometer is used to take an oral temperature?
- A digital thermometer is used to take an oral temperature. It is a small hand-held device with a “window” showing your temperature in numbers. There are many kinds of digital thermometers. Most digital thermometers are easy to use and measure body temperature within seconds. Carefully read the instructions before using your digital thermometer.
- Glass thermometers with alcohol inside may also be used for oral temperatures. This thermometer is a thin glass tube with a red or blue line inside it. These thermometers are safe to use for people over the age of 5. A child younger than 5 may bite the thermometer, breaking it in their mouth.
- In the past, mercury (MER-kure-e) thermometers were used. This thermometer is a thin glass tube with a silver tip and line inside. The silvertip and line is mercury. Mercury is a toxic and hazardous chemical. The Environmental Protection Agency (EPA), the American Academy of Pediatrics (AAP), and other organizations warn against using mercury thermometers. If the thermometer breaks, the mercury may be breathed in or absorbed (soaked) into your skin. If a glass thermometer breaks while checking an oral temperature, the mercury may be swallowed. Mercury is bad for your health, as well as for the water, wildlife, and waste systems on earth.
- If you have a mercury thermometer, replace it with a digital thermometer. You may also replace it with a glass thermometer having alcohol or galinstan instead of mercury in it. If your mercury thermometer breaks, do not touch the thermometer or the mercury. Do not try to clean up the spill. Open your windows to air out the area. Take children and pets out of the area right away.
