Receding
Gums - An Anatomy
Gum Recession Explained
Gingival or gum recession is a condition where the protective
tissue around your teeth is lost and pulls away towards
the root.
There are two major oral health issues
that can cause the receding loss of tissue around the teeth,
thereby causing possible temperature sensitivity and also
expose the less dense root area of the tooth to decay.
Receding gums can be caused by improper
tooth brushing (toothbrush abrasion) and also by periodontal
disease (gum disease).
In toothbrush abrasion, the enamel
at the gum line is worn away by scrubbing the sides of the
teeth in a washboard fashion. Over time, this horizontal
brushing wears away the protective enamel, exposing the
inner nerve-containing part of the tooth called dentin.
Dentin is comprised of tiny tubules
which extend from the surface of the tooth to the nerve
of the tooth. Once the necks of the teeth are worn through
and the gums have receded, cold temperatures and sweets
touch the outside of these dentin tubules and the stimulus
is extended to the nerve which is perceived as pain.
Methods of reducing the discomfort
to touch and temperature changes include:
- Use of a desensitizing toothpaste
- Have bonded resin restorations placed over the worn areas
along the necks of the teeth
- Cover exposed sensitive root surface
areas with soft tissue grafts
The other major cause for gum tissue to recede or shrink
away from the necks of the teeth is periodontal gum disease
and bone loss.
Inadequate brushing and flossing
allows bacteria to sit in between the teeth which causes
a chronic low grade gum infection. This leads to toxins
being released by the bacteria which painlessly causes the
bone to get eaten away from around the teeth.
As the gum disease progresses, the
teeth appear longer and the gums undergo recession along
with the bone loss.
Periodontal disease can start during
teenaged years and may progress painlessly for years before
actual awareness of the condition emerges. Bone tissue usually
wears away from around the roots of the teeth faster than
the diseased gum tissue.
What is created during this cycle
of periodontal disease is deep gum pockets which are very
hard to clean out and contain millions of bacterial cells
that continue to destroy bone. As more bone support is lost
around the roots of the teeth, they can become mobile and
loose. These events are usually accompanied by foul breath.
Patients with suspected gum disease,
and especially with recession of the gum tissues, should
undergo a thorough periodontal examination including a periodontal
probe screening to check for gum pockets and bone loss.
The earlier a periodontal gum disease problem is diagnosed
and treated, the better long-term prognosis for eliminating
extensive tooth loss.
Although skilled dentists with substantial
experience in treating various stages of gum disease and
Periodontists can provide treatments to arrest the disease
and successfully restore the affected teeth .... it does
require treating the disease in its early stages.
Left untreated..... it will result
in significant loss of critical bone mass and structure...
thereby causing tooth loss with little hope of regaining
healthy teeth. In significant cases, the bone loss can prevent
the proper fitting of dentures.
