I forgot to add quarterly pocket cleaning and semi-annually checkups
with my hygenist and dentist to the regimen.

    This is of course the traditional approach, and as far as it goes, it
is valid.  The backbone of traditional periodontal therapy is careful
debridement of bacterial-laden deposits on the roots of the teeth,
pocket elimination therapy to minimize the anatomic sites subject to
infection by pathogens, followed by meticulous and regular oral hygiene,
and regular professional followup  This removes the more or less
organized bacterial plaque, without which (it is said) periodontal
disease will not exist.
    This works well for some patients, but not all.  The reasons for
variable outcomes probably include variable levels of oral hygiene,
professional expertise, and also microbial virulence and host factors
(immunology).  So what to do with patients who have done all this and
found it not effective?
    Antimicrobials are used, but generally they are used short term to
eliminate superinfection and bacterial resistance.  Some antimicrobials
are used longer-term, but generally in doses subtherapeutic as
antimicrobials, because they have been shown to inhibit enzymes
implicated in periodontal breakdown.  These seem to work, but are far
from a panacea.
    As you can see from my description, there is not yet a "magic bullet"
to stop the periodontal process.  For most patients, your "simple goal"
will be very effective for those patients who can achieve it.  However,
after 31 years I must conclude that for most patients that "simple" goal
just ain't so simple.
