At what age can children have their temperature taken orally?

Oral temperature measurement is typically recommended for children who are older than 4 years. At this age, most children can understand the instructions and hold the thermometer in their mouth correctly for an accurate reading. The oral method is more reliable and provides better accuracy than other methods, such as axillary (under the arm) or tympanic (ear), for this age group.

Younger children, particularly those under 3 years, may not be able to cooperate or keep the thermometer in place, leading to inaccurate results and potential discomfort. The other options suggest either younger age groups that are not suitable for oral temperature taking or a scenario that limits oral measurement to a specific setting, which does not reflect the appropriate age guidelines for this practice.
