What is a common symptom of dental caries?

A common symptom of dental caries is tooth sensitivity or pain. This occurs because the decay process damages the tooth structure, leading to exposure of the dentin and pulp, which are sensitive to temperature changes and physical pressure. When dental caries progress, they can create cavities that irritate the nerve endings in and around the tooth, resulting in discomfort or a sharp pain response to hot, cold, or sweet stimuli.

While swollen gums can occur in conjunction with dental decay, particularly if the caries result in infection or periodontal involvement, they are not a direct symptom of caries. Uncontrolled bleeding typically indicates a more severe oral health condition, such as advanced gum disease, rather than dental caries specifically. Persistent jaw pain is often related to issues such as temporomandibular joint disorders or sinus problems, not directly linked to the presence of dental caries. Understanding these distinctions helps in effectively identifying symptoms related to oral health issues.
