My dentist said my gums look fine. Why do I need a deeper evaluation?

Because "looks fine" is a visual assessment, and periodontal disease is not diagnosed by looking. It is diagnosed by probing pocket depths, inserting a calibrated probe between the tooth and gum tissue at six points per tooth and measuring the depth of the sulcus. Numbers of 1–3 mm indicate healthy tissue. Numbers of 4 mm or above indicate periodontal pockets where gram-negative anaerobes establish biofilm communities that generate chronic bacteremia. Without probing, you have no information about your periodontal status. The absence of visible recession, absence of bleeding you notice, and absence of pain are not reliable indicators of gum health. Periodontal disease is characteristically painless in its early-to-moderate stages, which is the primary reason it advances undetected in men who "have never had a problem with their teeth."

A man who has not had a dentist probe his gum sulcus has not had a periodontal evaluation. He has had a visual inspection. These are not the same clinical procedure. Ask for periodontal charting at your next appointment. It takes fifteen minutes and provides a complete picture of gum health that no visual examination can give. (Tonetti et al., Journal of Clinical Periodontology, 2018)

Cardiologist's calibrated position, Solid (1) for probing as the diagnostic standard. Visual inspection alone is insufficient for excluding periodontal disease.

What to do: At your next dental appointment, specifically ask: "Can you do a full periodontal charting with pocket depth measurements?" If pocket depths of 4 mm or above are identified, ask for a referral to a periodontist.
