Which term describes soft deposits on teeth near the gums and between the teeth that consist of bacteria and their by-products and contribute to dental caries?

• A. Halitosis
• B. Dental plaque
• C. Gingivitis
• D. GERD

Answer: (B)

The term is dental plaque. This describes the soft, sticky film that adheres to teeth along the gumline and between teeth, composed of bacteria and their by-products. When plaque accumulates, the bacteria metabolize sugars in the mouth and produce acids that can demineralize tooth enamel, leading to dental caries. Plaque is the material that can also irritate gums and contribute to gingivitis, but the deposits themselves are what matter here. Halitosis refers to bad breath, gingivitis is the gum inflammation caused by plaque buildup, and GERD is acid reflux from the stomach—unrelated to the tooth deposits described. Regular brushing and flossing disrupt and remove plaque, helping prevent caries.
