Periodontitis is an infection of the bone and gums which surround the teeth. It is caused by the bacteria which normally reside in your mouth. When the bacteria become more numerous than normal, or at a level which your body can not tolerate, an inflammatory
reaction takes place and your body begins to destroy
the bone which supports the teeth. When the bacteria
in your mouth cause bone loss, the gum tissue does not
always recede away with the lost bone. Pockets are
created which harbor more bacteria and are unreachable
with a normal toothbrush and floss. The deep pockets
perpetuate the cycle of bone loss. The teeth subsequently
become loosened, and if not treated in a timely manner,
the teeth can even be lost.
During this process, there can be a foul odor from the
mouth, as well as infection (pus) coming from the gums.
But this process is usually painless and can sometimes
go unnoticed for quite sometime until significant
symptoms, such as bad breath or loose teeth, indicate
a problem.
