Galveston County Daily News, July 25, 2007 Column by Drs. Sally Robinson and Keith Bly GALVESTON - There are many oldwives tales surrounding teething, including that it gives a baby fever, makes them fussy, causes drooling and gives them diarrhea. Teething has been blamed for many conditions throughout history, including as a cause of death.  The symptoms associated with teething are not present in every infant. Some babies may show an increase in chewing, drooling and decrease in appetite, but some infants have no symptoms at all. A runny nose, fever, vomiting and diarrhea are signs of illness, not of teething, but a baby's temperature may be slightly higher than normal if he or she is teething. If your baby develops a high fever, vomits or has diarrhea, contact your pediatrician. Saliva production begins at about 2 to 3 months of age, when the salivary glands begin working. Many parents think that drooling is a sign of teething, but it is just part of a baby's normal development.  For most infants, teething is painless, but some do experience some discomfort. A baby's gums may become swollen and red about four to five days before or after their tooth appears, but the swelling does not last for weeks or months.
