Periodontitis can be identified early during dental exams. To prevent further gum damage, your periodontist monitors the condition of your gums over time. For this reason, regular dental visits are essential.

Several stages are involved in the diagnosis of gum disease;

1. Clinical examination

The only way to properly assess the condition of the gums and the teeth is through clinical examination. In the first visit, your dentist will complete a necessary periodontal test that lasts a few minutes.

The test helps your dentist determine if you have gingivitis or periodontitis. The dentist will use a dental probe to measure the pocket groove located between your gums and teeth during the examination. 


A healthy mouth has a pocket depth of 1 and 3 millimetres. When the pocket measures 4 millimetres, it is a sign of periodontitis.  A 4-millimetre pocket is an indicator of periodontitis. Furthermore, pockets that are more than 5 millimetres deep cannot be cleaned effectively. Your dentist also records the height of your jawbone. 

2. X-rays

After the clinical examination, an x-ray is required to confirm periodontitis. Your dentist will only use two images for simple cases, but they will use 14 x-rays for the whole mouth for extensive issues. The collected photos will show the entire jawbone, which will help the dentists evaluate the degree of bone loss. 

3. Microbiological tests

The microbiological tests give dentists an idea of the composition of the harmful bacteria present in your teeth that cause the build-up of plaque and tartar. In addition, the results of the microbiological tests enable the dentist to give you suitable and personalized dental care. 

4. Identifying the disease

In classifying the cases of gingivitis and periodontitis, there is a recognized international system. The issues are based on stages and grades. The stages define the extent of a disease, while grades indicate how fast the disease will progress.


With this classification, dentists can offer an appropriate dental solution to patients.
