A simple interdental brush test can reveal a lot about your health.
Used gently and horizontally, any bleeding suggests inflamed gums (gingivitis), which is reversible.
If the brush smells unpleasant afterwards, it may indicate anaerobic bacteria linked to periodontal disease, which is often irreversible.
Uncontrolled gum bacteria can enter the lungs or bloodstream and contribute to wider health problems.
Healthy gums help protect your whole body.
