All about periodontal grades
How periodontal disease (gum disease) is graded and treated
There are a number of factors used to assess the oral health of dogs and to allocate periodontal grades to each one checked.
- The symptoms of gum disease, e.g. the health of the gums.
- The depth of the pockets between the gum and the teeth (this is measured using a calibrated probe. In a dog with healthy gums the normal depth is 2-3 mm.
- The x-ray results.
- The amount and distribution of plaque and calculus.
After assessing these criteria, the severity of periodontal disease present can be determined and a probable outcome or prognosis made.
Periodontal grades and treatment chart
For ease of understanding where your dog's current dental diagnosis fits, we have prepared the following chart as a general guide to periodontal grades.
