Urgent! . Take your baby to the doctor. Teething or not.
Not From Teeth. Teething does not actually cause a fever. Viral infections do most of that. Teething can cause stress to the body and in turn make the child more likely to get a viral infection and there by get a fever, but it may not be related to teething at all. Treat the symptoms with otc infant tylenol (acetaminophen) and if it persists then see your provider for care.
