Dental caries, also known as cavities, are holes or gaps in tooth enamel, the hard outer layer of teeth. These holes can be caused by various factors, including poor oral hygiene, eating sugary foods and drinks, and inadequate fluoride intake.
The bacteria Streptococcus mutans, present in plaque on teeth, is the primary initiator of dental caries. When plaque is not removed effectively, the bacteria produce acids that dissolve enamel and promote the development of cavities.
The process of dental caries can be divided into three main stages: plaque formation, acid production, and cavity formation.
Plaque formation: Bacteria like S. mutans adhere to the surface of tooth enamel and produce acids that disrupt the enamel's structure. This process, known as plaque buildup, allows the bacteria to penetrate the enamel and begin the formation of cavities.
Acid production: As plaque accumulates and the enamel weakens, it becomes more susceptible to acids produced by the bacteria. These acids further dissolve enamel, creating the holes and cavities observed in dental caries.
Cavity formation: When the enamel is completely dissolved and eroded, a cavity is formed. This cavity can be filled with soft tissue or dental fillings to repair the damage and strengthen the tooth.
Dental caries can manifest differently in children and adults. Symptoms include visible holes or cracks in teeth, tooth pain when eating or biting, sensitivity to hot and cold foods and drinks, and bad breath.
Regular dental checkups and cleanings are essential for early detection and treatment of dental caries. Early intervention can help prevent further damage and preserve the health of teeth and gums
