Dentures may negatively impact a person's overall nutrition, research suggests

Dentures may have a potentially negative impact on a person's overall nutrition, according to new research from Regenstrief Institute and Indiana University School of Dentistry. The research team leveraged electronic dental and health records to gain a better understanding of how oral health treatments affect individuals' overall health over time.

This is believed to be the first study to report the results of utilizing lab values of nutritional biomarkers and linking them with dental records.

Dentures are a significant change for a person. They do not provide the same chewing efficiency, which may alter eating habits. Dentists need to be aware of this and provide advice or a referral for nutrition counseling. These patients need support during the transition and possible continued monitoring."

For the study, the research team matched the dental records of more than 10,000 patients in Indiana with medical laboratory data, specifically markers for malnutrition. The laboratory tests included complete blood count, basic metabolic profile and lipid and thyroid panel tests, among others. They compared the lab results from two years before a patient received dentures to the two years after.

Researchers found that people with dentures had a significant decline in certain nutrition markers over those two years. People who did not wear dentures did not experience this decline. The marker levels were still within normal range, but researchers say there is the potential that the levels will continue to fall as more time passes. They urge dentists to be aware of this possibility.

The next steps in this research area are to look at other factors that may influence nutrition, including insurance status and dental clinic characteristics.

    The only contact with my dentist after receiving dentures is their requirement for referral to ‘their’ denturist.  (A money grab in my opinion since I can go to most any other denturist WITHOUT a referral). And, I’ve never heard of a Dentist consulting a patient about nutrition.

    My nutrition is most definitely negatively impacted.  Having Lupus with co-morbidities, i.e. osteoporosis from long term prednisone usage, my jaw bones have receded excessively so much so that my bottom plate cannot be fitted for proper chewing.  Eating raw vegetables was one of my favourite eats, even before the bone loss and after the dentures, I could no longer eat raw vegies unless I cut them into itty bitty pieces.  It is my belief that because of the loss of vegies in my diet (cooked vegies just aren’t the same as raw), I developed MFLD (metabolic fatty liver disease).  What a wonderful life eh?
