Periodontal disease is diagnosed by your dentist or dental hygienist
during a periodontal examination. This type of exam should
always be part of your regular dental check-up.
A periodontal probe (small dental instrument) is
gently used to measure the sulcus (pocket or space) between the tooth
and the gums. The depth of a healthy sulcus measures three millimeters
or less and does not bleed. The periodontal probe helps indicate
if pockets are deeper than three millimeters. As periodontal disease
progresses, the pockets usually get deeper.
Your dentist or hygienist will use pocket
depths, amount of bleeding, inflammation, tooth mobility, etc., to
make a diagnosis that will fall into a category below:
Gingivitis
Gingivitis is the first stage of periodontal disease. Plaque and
its toxin by-products irritate the gums, making them tender, inflamed,
and likely to bleed.
Periodontitis
Plaque hardens into calculus (tartar). As calculus and plaque continue
to build up, the gums begin to recede from the teeth. Deeper pockets
form between the gums and teeth and become filled with bacteria and
pus. The gums become very irritated, inflamed, and bleed easily.
Slight to moderate bone loss may be present.
Advanced
Periodontitis
The teeth lose more support as the gums, bone, and periodontal ligament
continue to be destroyed. Unless treated, the affected teeth will
become very loose and may be lost. Generalized moderate to severe
bone loss may be present.
