What is a common symptom of dental caries that should not be ignored?

Pain in the affected tooth is a common symptom of dental caries that signifies the presence of decay and the potential for further complications if not addressed. This pain can range from mild discomfort to intense pain, depending on the severity of the caries and whether the decay has progressed to involve the pulp of the tooth. Ignoring this symptom can lead to more serious issues such as infection or abscess, which would require more invasive treatments.

When dental caries develops, it damages the enamel and can lead to sensitivity or pain when consuming hot, cold, or sweet foods. Recognizing and acting on tooth pain early is crucial for preserving the tooth structure and preventing more extensive dental work later on.
