The Importance of an Accurate and Complete Medical History in Dentistry

Having spent 25 years in clinical practice, I can say with conviction that the medical history remains the single most underestimated tool in the dental clinician’s arsenal. Time pressures, digital form-filling, and the routine nature of dental appointments have, in many practices, reduced this critical process to confirm that all the boxes have been checked.

Within the last couple of years, the providers and team members at Mequon Smile Design have found patients frequently underreport or fail to disclose relevant medical information — not out of deception, but because they simply do not appreciate its relevance to dental care. We have encountered patients who neglected to mention bisphosphonate therapy (for osteoporosis or cancer) until after an extraction had been planned, or who omitted recent cardiac stent placement because they considered it “dealt with.” Most commonly, and probably the most frustrating for the dental team and patient as it results in the necessity to reschedule a dental appointment, but patients fail to relay that they have had recent joint replacements. These oversights carry extreme clinical consequences. Bisphosphonate-related osteonecrosis (dead bone exposure) of the jaw remains a devastating and largely preventable complication; antiplatelet regimens in post-stent patients can present serious bleeding challenges; failure to inform your provider of a recent hip replacement could result an infected, failed prosthesis. The burden falls on us as clinicians to ask the right questions thoroughly, systematically, and without assumption.

A written questionnaire, however well designed, is only the beginning. The real medical history is taken in conversation. Over the years, I have found that a brief, focused verbal review and asking patients to walk me through their current medications, any recent hospital visits, or changes in their general health, gives us invaluable information that the form alone does not. It also helps to build trust. Patients who feel listened to are more open more compliant with treatment, and more likely to disclose sensitive conditions such as immunosuppression, substance use, or mental health diagnoses which can affect care.

The oral cavity does not exist in isolation. Poorly controlled diabetes accelerates periodontal destruction and compromises healing. Sjögren’s syndrome and its associated xerostomia dramatically elevate caries risk. Patients undergoing head and neck radiation face lifelong risks of osteoradionecrosis (dead bone) following dental extractions, a risk that demands careful pre-radiation dental screening and clearance, as well as long follow-up. These are not rare cases and dental conditions and identifying them requires a thorough medical history.

As a reminder to our readers, the medical history is not just paperwork. It is the foundation upon which every safe clinical decision is built and helps your dental team provide dental treatment that is predictable with reduced complications. Failure to mark that checkbox or relay relevant changes to your medications or health to your hygienist or dental team may result in avoidable consequences.
