When you’re leaning back and the dentist starts checking your gums with a metal instrument saying a series of numbers, it might seem a little strange.

Not to worry – what we’re doing is called periodontal charting, and it can help us identify gum disease or other health concerns before you feel them.

What is periodontal charting?

Periodontal charting is the practice of using a periodontal probe to measure the distance between your gums and where they attach to your teeth. This area or space is often called a “pocket,” and the size of these pockets is an indicator of how healthy or unhealthy your gums and bone support are. These measurements are one of the many ways that Tri-City Dental Care WA can evaluate the health of your gums and screen you for gum disease.

We often check your gum health with a dentist or hygienist probing your gums and another team member recording the results in a periodontal chart like the one below:

What do the numbers mean?

The numbers that you hear are the depths of the pockets around your teeth in millimeters. Smaller, tighter pockets usually mean healthier gums.

  • 0-3mm without bleeding means you are in great shape. Be proud!
  • 1-3mm with bleeding is an early sign of gingivitis. Better at-home care will probably get you back on track!
  • 3-5mm without bleeding means gum disease is possible. We’ll help you with some instructions for home and possibly schedule another visit a little sooner.
  • 3-5mm with bleeding could be the beginning of gum disease. This can require additional treatment and more frequent visits.
  • 5-7mm with bleeding means tissue damage and probably bone loss. More hygiene visits and special treatment will probably be necessary in addition to better at-home care.
  • 7mm and above with bleeding is generally the advanced stage of periodontal disease. Surgery to repair bone loss and frequent periodontal maintenance will be required.

Measuring your pocket depths is just one of the things that we do to screen you for gum disease. In addition to the measurements, we visually look for signs and symptoms, consider your risk factors, and take digital X-rays.

Why is periodontal charting important?

As we mentioned above, the main reason we probe your gums is to check for gum disease, also known as periodontal disease.Science supports the fact that gum disease affects other parts of your health. Research has suggested that there is a link between gum disease and many other conditions such as heart disease, diabetes, osteoporosis, respiratory issues, and many more.

Periodontal disease can have many signs and symptoms. These include:

  • Bleeding while brushing, flossing, or when eating certain foods
  • Red, swollen or painful gums
  • Bad breath
  • Gums that are pulling away from the teeth
  • Loose teeth

Gum disease is often silent and progresses slowly. Measuring the pockets is a proactive approach. Most of the above symptoms will not occur until an advanced stage of gum disease which is more difficult to treat. Early intervention allows for less invasive, more predictable treatment and better results.
