Bacterial tooth decay, also known as dental caries, is a widespread oral health issue caused by the breakdown of tooth enamel due to acids produced by bacteria. Here's an overview:<br /><br /> Causes<br />Tooth decay occurs when bacteria in the mouth metabolize sugars from food and beverages, producing acids. These acids demineralize the hard tissues of the teeth, such as enamel and dentin, leading to cavities<br /><br /> Risk Factors<br />- High sugar consumption.<br />- Poor oral hygiene.<br />- Reduced saliva production, which can be caused by certain medications or medical conditions.<br /><br /> Prevention<br />- Oral Hygiene: Brushing teeth twice daily with fluoride toothpaste and flossing regularly.<br />- Diet: Limiting sugary foods and drinks.<br />- Fluoride Use: Fluoride strengthens enamel and helps prevent decay<br /><br /> Treatment<br />- Early Stages: Fluoride treatments can reverse minor decay.<br />- Advanced Stages: Fillings, crowns, or root canals may be necessary to restore damaged teeth<br /><br />Tooth decay is preventable with proper care and regular dental check-ups<br /><br />Al-Mustaqbal University, Iraq's first university."
