A tiny cavity may seem harmless, but it’s actually a bacterial infection that can progress beyond the tooth. Bacteria feed on sugars, producing acids that erode enamel and reach the dental pulp, where nerves and blood vessels reside. At this stage, the infection is no longer contained.
If untreated, bacteria can form a dental abscess and spread to the jawbone, face, neck, or bloodstream. Serious complications may include infective endocarditis, deep neck infections, sepsis, or even brain involvement. These events, while uncommon, are well documented in medical and dental literature.
Cavities often develop silently, with pain appearing only after significant damage. Prevention is simple but critical: proper brushing, daily flossing, reduced sugar intake, and regular dental check-ups can protect both your teeth and overall health.
