The infants in the study had up to seven erupted teeth when the study started. They did not have a history of conditions that could cause symptoms related to teething.
The researchers visited the infants' homes daily over an eight-month period. They took the babies' temperature inside the ear and under the arm. The researchers asked the mothers to describe any symptoms their baby had in the last 24 hours.
The symptoms were recorded every day on a chart. It was also noted on a daily basis if the tooth was erupting or not.
