I am a 66 year old female with excellent teeth and gums. Recently I have been experiencing sore gums. I went to my dentist and he could not find any reason for the pain. He prescribed Chlorhexidine (Peridox) rinse 2x a day for 3 weeks. The pain went away but after a week off the rinse the pain is now back. My dentist suggested using the Chlorhexidine for another 30 days. Anyone experienced anything like this issue? Thank you
