What’s a potential consequence of untreated cavities?

Untreated cavities can lead to pulpitis or a tooth abscess, which are serious dental conditions. When a cavity forms, it creates a pathway through the enamel and into the deeper layers of the tooth. If the decay progresses, it can reach the pulp—the innermost part of the tooth containing nerves and blood vessels—which may become inflamed and infected, resulting in pulpitis. If the infection continues untreated, it can lead to the formation of a tooth abscess, characterized by the accumulation of pus at the root of the tooth or in the surrounding tissues. This condition is painful and can lead to further complications, including systemic infections, if bacteria enter the bloodstream.

In contrast, while untreated cavities can also impact gum health or contribute to increased tooth sensitivity, these effects occur primarily secondary to the decay and may not carry the immediate severity of pulpitis or abscess formation. Improved overall dental health is not a consequence of untreated cavities, as neglecting treatment typically exacerbates dental issues.
