Don’t neglect an oral health exam for older patients.
It is easy to be rushed and cut corners in the ED, and for my residents this often means a less than thorough (if any) examination of the mouth. If the chief complaint is not “dental pain” or “sore throat” the mouth seems to fall off their physical exam list. This may not be as critical in the healthy 25-year-old, but for the older adult patient, the oral exam can often provide important diagnostic clues. In addition to chief complaints of sore throat or dental pain, a mouth exam is an essential part of the medical workup for fevers, failure to thrive, dysphagia, headaches, pneumonia and shortness of breath.
Older adults are at higher risk for oral infections and chronic oral conditions that can affect their systemic health. Daily hygiene may be neglected by the patient or caregivers due to physical or cognitive limitations or lack of caregiver education and training in oral health.
Only 64% of adults ≥ 65 years old have had a dental visit in the past year.(1) Biases may contribute to this as well, as some people assume that patients without teeth do not need to see a dentist. About a fifth of older adults are edentulous, and these patients still require oral evaluations. This condition can actually predispose them to poor nutrition and complications from oral prosthetics (such as dentures).(2)
Additionally, routine checks and maintenance can pick up oral cancers earlier, and all older adults are at higher risk for these. The physiologic changes of aging also place this population at higher risk for oral lesions and infections.(3) An aging mouth is not an exception in an aging body, and with aging comes hyposecretion of salivary glands, changing stages in lining cells and resorption of soft and hard tissue (gum recession). Increased bacterial accumulation in the oral cavity leads to a higher risk of aspiration pneumonia.(4) In addition to physiologic changes, multiple chronic health conditions and medications cause xerostomia (dry mouth), which also contributes to pain and difficulty eating. (5)
Patients with autoimmune diseases such as Rheumatoid Arthritis, Systemic lupus erythematosus, diabetes mellitus, autoimmune thyroid disease, multiple sclerosis and HIV/AIDs are at high risk for oral lesions and slow healing.(6) Oral lesions may occur due to an ill-fitting removable oral prosthesis (dentures or bridges), trauma (falls) or simply as a result of bacterial or fungal accumulations (Figures 1, 2, and 3).
Immunocompromised patients are also at higher risk for tooth loss and malnutrition. Dietary deficiencies worsen these oral conditions and leads to a cyclic, negative reinforcement of disease.
Older adults with oral health issues can also present atypically. Those with cognitive decline do not complain of pain as a 25-year-old with a dental abscess would, or may feel it as headaches or nausea or lack of appetite. The first expression of oral pain is often decreased oral intake, presenting as dehydration and nutritional deficits. In one study of ED patients ≥ 65 years old, 12% qualified as having malnutrition and of those, over half listed poor oral health as the cause.(7)
Think about it: how many older patients have you seen this past month who present with headaches, sepsis with unknown source, aspiration pneumonia, failure to thrive or poor oral intake, or concern for abuse/neglect? All these patients should have a good oral exam and many will need urgent referral to a dentist as part of their care. Every patient with aspiration pneumonia should be referred to a dentist for intensive preventative dental care to reduce bacterial overgrowth. Any patient you intubate and note “poor dentition” in your note should have aggressive oral hygiene (by a dental team if possible) while in the ICU.(8) Studies have shown that proper oral care can not only reduce the risk of future infections, but also reduce mortality from hospital acquired pneumonia.
Many hospitals and long-term care facilities do not have dentists on staff and nurses and care givers may not have adequate training to care for oral health of the elderly. Residents in long-term care facilities can develop dental/ oral diseases tend to have a serious problem, particularly when routine dental care is neglected.(9) Actually looking in the patient’s mouth and relaying the importance of good oral health back to the patient and caregiver is more likely to improve that patient’s quality of life far more than the tetanus booster you just updated or the screening for tuberculosis your ED nurse did. Oral health is an essential part of all patients’ health, but it is especially critical for vulnerable older adults. So next time… look in the mouth.

Dental disease is largely preventable. Many older adults, however, experience poor oral health. National data for older adults show racial/ethnic and income disparities in untreated dental disease and oral health–related quality of life. Persons reporting poor versus good health also report lower oral health–related quality of life. On the basis of these findings, suggested public health priorities include better integrating oral health into medical care, implementing community programs to promote healthy behaviors and improve access to preventive services, developing a comprehensive strategy to address the oral health needs of the homebound and long-term-care residents, and assessing the feasibility of ensuring a safety net that covers preventive and basic restorative services to eliminate pain and infection.
