Q2:Is
gingival bleeding caused by periodontal
disease?
A2:
Among the host defense cells (neutrophiles,
macrophage, and lymphocyte), neutrophiles
fight in the forefront counteracting against
periodontal bacteria with host defense
system (immune response). When the harmful
bacteria invade periodontal tissue, a
net of capillary vessel is developed inside
gingiva to carry neutrophiles to the front
line (periodontal tissue), causing redness
in gingiva and leaving it easy to bleed.
Although its occurrence rate is low in
total periodontal diseases, there is also
a type that does not accompany gingival
bleeding (early-onset periodontitis or
aggressive periodontitis). In this type
of periodontal disease, periodontal tissues
do not manifest neutrophiles even when
periodontal tissues are attacked by bacteria.
Since capillary network is not formed,
no redness or bleeding appears in the
gums. However, despite the lack of bleeding,
periodontal disease advances and resorption
of alveolar bone occurs. In these cases,
patients do not realize abnormalities
in their periodontal tissues until the
disease advances and their teeth become
loose. Having these tragic cases as exception,
generally "gingival bleeding" can be acknowledged
as a helping sign for us to realize the
manifestation of periodontal disease.
In most cases, persistent gingival bleeding
or swelling is caused by periodontal disease.
Whatever the level of the periodontal
disease may be, we recommend you to visit
and consult with your dentist without
hesitation.
