periodontitis
"I tried the oral rinse chlorhexidine because I was going in for a first appointment with my (now) periodontist.  I wanted to look healthy, and not have as many problems with aging, since I'm getting up to retirement age.  The rinse made me feel like I was doing something good for myself.  I didn't see any results at first but after several treatments my gums and tongue turned pinker and a cracked tooth that was causing pain fell out on its own."
