What does “Bleeding on probing” mean?
Bleeding on probing (BOP) records whether the gums bleed when the sulcus is examined with a periodontal probe. It may relate to bleeding seen during brushing, but is specifically a finding under examination conditions.
What is recorded during examination?
The dental team records pocket depths and bleeding after probing at multiple points around teeth. The location and extent of bleeding help identify inflammation and areas that are hard to maintain. Examination conditions, including probing pressure, also affect findings, so bleeding at one point alone does not determine disease stage.
Bleeding versus a periodontitis diagnosis
Bleeding is a clue to gum inflammation but does not directly quantify supporting tissue destruction. Periodontitis is assessed together with attachment loss and bone condition on radiographs. Smoking and other factors may affect bleeding, so little bleeding alone does not establish health.
Using examination results to guide care
Plaque, tartar, brushing, and interdental cleaning at bleeding sites are checked and compared again after treatment. Continually avoiding cleaning because an area bleeds can leave plaque behind. However, do not scrub forcefully or examine with sharp tools; obtain guidance on appropriate cleaning.
Frequently Asked Questions
Does BOP immediately mean periodontitis?
No. It can occur in gingivitis too. Diagnosis requires pocket depths, attachment loss, and radiographs to be considered together.
Can I test by pressing my gums at home?
BOP is a finding recorded during dental probing. Deliberately making your gums bleed at home does not help diagnosis. Report the location and duration of repeated bleeding during brushing at your appointment.

Has supporting tissue damage been found as well as bleeding?
Explanation and evidenceDistinguishing bleeding alone from bleeding with attachment and bone loss helps explain the treatment extent.
