7-10 days usually: During this time have her eat softer foods and avoid acidly foods (soda, ketchup, tomato sauce, etc.). Have her rinse with warm salt water several time a day. If it interferes with eating have her rinse (not swallow) with a mixture of malox and liquid benadryl (diphenhydramine). If other cold symptoms develop then see your pediatrician.
