Oral hygiene linked to metabolic health and weight management

Recent research suggests a significant link between oral hygiene and metabolic health. The oral microbiome, consisting of hundreds of bacterial species, plays a crucial role in systemic health. Poor oral care can lead to an increase in harmful bacteria and plaque, which may impact weight management through several mechanisms.

First, periodontal disease can cause chronic inflammation. Toxins released by bacteria can enter the bloodstream, interfering with insulin function and blood sugar control, which may lead to increased fat storage in the liver. Second, the ‘oral-gut axis’ suggests that harmful oral bacteria can travel to the intestines via saliva, potentially disrupting gut microbiota and lowering metabolism.

Additionally, poor dental health can reduce chewing efficiency, making it harder to feel satiety and leading to overeating. To support a healthy metabolism, experts recommend brushing teeth immediately after waking up and before bed, using dental floss or interdental brushes to increase plaque removal from 61% to 85%, and replacing toothbrushes every month.
