Dental Caries (Tooth Decay)

Dental caries, commonly known as tooth decay or cavities, is one of the most prevalent chronic diseases worldwide, affecting billions of people across all age groups. This bacterial infection causes progressive demineralization and destruction of tooth structure, beginning with the outer enamel and potentially extending to the inner pulp. Despite being largely preventable through proper oral hygiene and dietary modifications, dental caries remains a significant global health challenge, particularly affecting children, elderly individuals, and socioeconomically disadvantaged populations.

Overview

Dental caries is a multifactorial, biofilm-mediated disease characterized by the localized dissolution and destruction of calcified dental tissues. The process begins when cariogenic bacteria in dental plaque metabolize dietary carbohydrates, producing acids that demineralize tooth enamel. If left unchecked, this process progresses through the enamel into the underlying dentin and eventually may reach the pulp, causing pain, infection, and potential tooth loss.

The tooth structure consists of three main layers: the outer enamel (the hardest substance in the human body), the middle dentin (containing microscopic tubules), and the innermost pulp (containing nerves and blood vessels). Caries typically begins as white spot lesions on the enamel surface, representing early demineralization that can be reversed with appropriate interventions. However, once cavitation occurs and the enamel surface breaks down, restorative treatment becomes necessary.

Globally, dental caries affects nearly 100% of adults and 60-90% of school-aged children, making it the most common chronic disease worldwide. The prevalence varies significantly by geographic region, socioeconomic status, and access to preventive care and fluoride. In developed countries, the incidence of dental caries has declined substantially since the 1970s due to widespread fluoride use, improved oral hygiene practices, and better access to dental care. However, disparities persist, with higher rates observed in certain populations and communities.

The economic burden of dental caries is substantial, encompassing both direct treatment costs and indirect costs related to lost productivity, school absences, and reduced quality of life. Pain and infection from untreated caries can significantly impact an individual's ability to eat, sleep, concentrate, and perform daily activities. In children, severe dental caries can affect growth, development, and academic performance, while in adults, it can impact professional and social interactions.

Symptoms

The symptoms of dental caries vary depending on the stage of decay, location of the affected tooth, and individual pain tolerance. Early stages may be asymptomatic, while advanced caries can cause severe pain and complications.

Causes

Dental caries is a multifactorial disease resulting from complex interactions between bacterial factors, host factors, environmental factors, and time. Understanding these causative factors is essential for both prevention and treatment strategies.

The Caries Process: Primary Factors
