Final answer:
Dental caries, caused by bacteria such as Streptococcus, can lead to severe tooth decay and, eventually, to dental abscesses if not treated. Good oral hygiene and regular dentist visits, including X-ray imaging, can prevent and detect caries early to avoid complications.
Step-by-step explanation:
Dental caries are a form of tooth decay caused by bacterial action on the teeth, leading to cavities. These are typically due to an overgrowth of oral bacteria, particularly Streptococcus and Actinomyces species, which thrive in the absence of good dental hygiene. Dental caries can advance through the tooth layers, from the enamel to the dentin and possibly reaching the pulp, leading to potential abscesses and further complications if not treated promptly.
To prevent the worsening of caries, early treatment is crucial. This usually involves drilling to remove the decayed part of the tooth and then filling this space. Severe cases affecting the pulp may require a more extensive procedure like a root canal. Proper dental care, including regular brushing and flossing, can significantly reduce the risk of tooth decay.
Microorganisms contribute to tooth decay by forming a biofilm known as plaque, which sticks to the teeth. When you consume foods containing sugars like sucrose, oral bacteria break it down, resulting in acids such as lactic acid which then attack the tooth's hard substances. Regular dental check-ups, including X-ray imaging, help detect not easily visible decay that if left untreated may lead to more severe dental issues.
