As recently communicated by researchers in the Journal of Periodontology, significant weight gain demonstrates a strong correlation with either a reduced number of teeth or the deterioration of the bone and gum tissue anchoring those teeth.
The inability to chew properly, resulting from tooth loss, can restrict an individual’s selection of nutritious foods, the researchers stated.
“These findings contribute to the mounting evidence indicating that periodontal health is paramount for overall well-being, particularly as people age,” commented Ana Bevilacqua Gillo, President of the American Academy of Periodontology. “Preserving the health of one’s teeth and gums supports better dietary intake, the development of positive habits, and an enhanced quality of life in later years.”
For this study, scientists monitored over 900 individuals participating in a longitudinal health study conducted in Pittsburgh, Pennsylvania, and Memphis, Tennessee. Upon enrollment, participants underwent an oral examination documenting edentulism and the presence of gum disease.
Over the ensuing four years of observation, the researchers observed that nearly 12% of participants experienced an increase in body weight equivalent to at least 5% of their initial mass.
The investigation revealed that individuals with fewer teeth and poorer oral health status tended to gain more weight.
The researchers postulate that tooth loss may cause individuals to shy away from high-fiber, nutritious items like fruits and vegetables, opting instead for softer foods that often carry a higher caloric load.
Researchers found that molars, which are essential for grinding food during mastication, were particularly significant in the risk of weight gain. Those lacking molar teeth exhibited a 17% greater likelihood of gaining weight.
“The absence of functional teeth, especially molars, correlated with a higher probability of weight gain in older adults over the 4-year period,” concluded the research team, led by Professor Natália Paula from the Federal University of Pelotas in Brazil.
The researchers suggested that for individuals aiming to maintain a healthy weight, or perhaps shed a few pounds, incorporating good oral hygiene maintenance into their strategy would be advisable.
Nevertheless, they pointed out that further investigation is warranted to fully grasp the underlying connection between tooth loss and weight gain.
