I am in med sales - nothing to do with dentistry at all.  I want to
share something I have learned by accident - many of you probably know
this already.  About 18 months ago asked a friend who had a bout with
gum recession what he had done and how it worked out.  Well he bought
a waterpik, used a mixture of largest bottle of Target mouthwash
(cheap) along with 1/2 a mouthwash cap full of hibiclens - available
from Walgreens for approximately $10 for 8 ounces.

I had a significant halitosis problem coming from one particular area
in my upper molars - so I really worked that area over with the
waterpik and mouthwash/hibiclens solution.  After about 6 months the
halitosis went away.  Recently I noticed to my amazement the gum
recession I previously had in that area was gone.  Called my friend
and he said the same thing had happened to him.  Hibiclens is a
cleaning and disinfection agent - makes the mouthwash solution foam
when it goes through the waterpik.  I now fill up the waterpik with
plain water and really go over all my teeth and then fill it up 1/4
way with the mouthwash solution and go around all my teeth.   Also you
want to brush your teeth afterwards - hibiclens will discolor your
tooth surfaces if it is left in contact with them.  Apparently the
active in hibiclens is also in very expensive prescription mouthwash.

Anyway someone on this group made some similar suggestions about
waterpik and that was what sparked the question to my friend.  I owe
that to the group to share.  Hope somebody can benefit
