What Is a Periodontal Probe?

A periodontal probe is a slender, calibrated instrument used to measure the depth of gum pockets and detect signs of periodontal disease, gingival recession, or bone loss.
        It helps dentists assess periodontal health, plan treatment, and monitor recovery over time.

In short:

  • Probes measure periodontal pocket depth.
  • Explorers detect tooth surface irregularities and caries.

Types of Periodontal Probes

Each probe is designed to perform a specific clinical function. Our range includes the most popular and internationally standardized types.

How to Use a Periodontal Probe

  • Insert the probe gently into the gingival sulcus.
  • Align parallel to the tooth’s long axis.
  • Read millimeter markings to determine pocket depth.
  • Record six measurements per tooth (mesiobuccal, midbuccal, distobuccal, mesiolingual, midlingual, distolingual).
  • Interpretation Guide:
  • 1–3 mm → Healthy sulcus
  • 4–5 mm → Early periodontal involvement
  • 6+ mm → Advanced periodontitis
  • Positioning
    • Patient seated upright, clinician at 9–12 o’clock position.
    • Use finger rest on chin or adjacent teeth.
  • Angulation
    • Insert probe parallel to long axis of the tooth.
    • For molars, walk probe into col area.
  • Insertion & Pressure
    • Apply light force (~20 grams) — equivalent to the pressure of pressing a pen’s clicker.
    • Probe should slide gently to the base of the pocket (not forced).
  • “Walking” the Probe
    • Move in 1–2 mm steps around the tooth (6 sites per tooth: mesio-buccal, mid-buccal, disto-buccal, etc.).
    • Record deepest reading per site.
  • Record Findings
    • Pocket depth, bleeding on probing (BOP), suppuration, recession, mobility.

Pro Tip: Use a mirror and light to visualize the probe tip exiting the gingival margin — confirms accurate depth.

Explorers such as Briault or Shepherd’s Hook are sometimes mislabeled as “probes,” but their true function is detection, not measurement.

Periodontal Probe Markings

Common calibration patterns include:

  • Williams: 1, 2, 3, 5, 7, 8, 9, 10 mm
  • UNC 15: 1–15 mm continuous
  • WHO: 3.5–5.5–8.5–11.5 mm with 0.5 mm ball tip

Markings help clinicians achieve consistent measurement accuracy.
