I have pain in a specific area of my gum (no tooth in that area) the only think that seems to alleviate the pain is cold water on the exact location. The dentist told me I have gum disease and gave me Chlorhexidine Gluconate Oral Rinse to use twice a day and ibuprofen 800mg for the pain. H e says there is no infection but how can it hurt so much with no infection? during day i go by with the help of the cold water but I didn't sleep for 36 hours now cause I have to keep taking the cold water to relieve the pain.. oragel didn't help anything either. Help Please!
