Skipping nighttime toothbrushing is more than a dental concern. Large clinical studies show that people who do not brush before bed face a higher risk of cardiovascular events over time.
During sleep, saliva flow decreases. Without brushing, dental plaque and harmful oral bacteria remain active longer, increasing gum inflammation and allowing inflammatory byproducts to enter the bloodstream.
Scientific evidence links periodontal disease with systemic inflammation, endothelial dysfunction, and atherosclerosis—key biological pathways involved in heart disease and stroke.
Brushing before sleep is a simple, evidence-based habit. It protects gum health, reduces oral bacterial load, and may contribute to better cardiovascular health as part of daily preventive care.
