As the bacteria that cause periodontal disease (see article
"Periodontics 101")
release toxic substances, they trigger the breakdown of gum
and bone. The gum then separates from the teeth, forming gaps that are called
periodontal pockets. Bacteria settle in these pockets and because they cannot be
removed by the patient's daily oral hygiene, they continue to accumulate and
reproduce. Without proper treatment, the bacteria will continue to populate
these pockets, creating further gum and bone destruction.
The first step in the treatment of periodontal disease involves the removal
of the bacteria that inhabit the periodontal pockets in the form of plaque and
tartar. The removal of the pocket irritants, scaling and root planing (see
article "Scaling and Root Planing"),
is combined with oral hygiene instructions
that are aimed at improving the patient's ability to control plaque and avoid
bacteria from reinfecting the periodontal pockets. Several weeks after
completion of scaling and root planing, a periodontal re-evaluation should be
completed to assess the healing response. If the
periodontal pockets do not
reduce to below 4 mm and the gums are still unhealthy, surgical treatment may be
indicated.
Pocket depth reduction is a term used for a series of different surgical
procedures (gingivectomy, flap surgery, osseous surgery). The purpose of these
procedures is to gain access to the root surface to effectively remove calculus
and to reduce the size of the pockets to help prevent bacteria from settling in.
What to Expect
Pocket depth reduction is done in the dentist's office with local
anesthesia (lidocaine). After lifting the gum back, the bacterial plaque and
tartar are removed from the root surfaces. It also may be necessary to remove
the infected gum tissue and to smooth the bone surface. Stitches (sutures) are
placed to aid in healing. The stitches are usually removed five to ten days
after the surgery. Follow-up appointments are scheduled as necessary to evaluate
healing and plaque control.
Post-surgical discomfort may last a few days and is usually minimal. It can
be easily managed with commonly available over-the-counter medications such as
aspirin, acetaminophen, or ibuprofen. Patients can expect to follow their normal
routine the day after surgery. A dentist will provide special instructions
related to diet, exercise, and medications.
After pocket depth reduction, patients may experience heightened tooth
sensitivity. This is temporary and usually resolves within a few weeks. There
are chemical aids available that help reduce sensitivity.
Some people also may experience looser teeth after periodontal surgery. This
also is a transient finding that occurs as part of the normal healing process.
With proper plaque control and bite adjustment, the teeth usually tighten up in
a few weeks.
Another concern after pocket depth reduction is that the teeth may appear
longer and that there are spaces in between the teeth. Actually, longer teeth
are the result of periodontal disease, not of periodontal surgery. As
periodontal disease infects and destroys the bone that encases the roots, the
root surfaces become exposed. They do not appear exposed because they are
covered by the inflamed, swollen gums that form the periodontal pocket. Without
proper treatment, the
periodontal pockets continue to deepen, giving way to more
infection, bone loss, and eventually tooth loss and systemic complications.
There are treatments that can help improve esthetics after periodontal
treatment. In addition to periodontal plastic surgery procedures, orthodontic
tooth movement (braces) or restorative treatment (crown and bridges) can help
create a more pleasing smile line.
Benefits
If
periodontal pockets do not resolve after scaling and root planing, a
dentist may recommend pocket depth reduction. Whether a dentist performs a
gingivectomy, periodontal flap surgery, or osseous surgery, the patient will
benefit from the reduction in pocket depth and the reattachment of the gums to
the root surface. Pocket depth reduction, when followed by supportive
periodontal treatment, is a predictable procedure that can help keep teeth
healthy and reduce the risk of serious health problems related to periodontal
disease. If a general dentist does not frequently do surgeries, he or she may
refer the individual to a periodontist that specializes in this technique.
