What are the most common dental diseases?

• A. Tooth fractures and gingivitis
• B. Dental caries and periodontal disease
• C. Halitosis and fluorosis
• D. Malocclusion and pulpitis

Answer: (B)

The main idea here is that two conditions stand out as the most widespread dental diseases: dental caries and periodontal disease. Dental caries happens when acids produced by bacteria in dental plaque dissolve the minerals of the tooth surface after frequent exposure to fermentable carbohydrates. Over time, mineral loss can create cavities. It’s extremely common across ages and is influenced by diet, oral hygiene, saliva, fluoride exposure, and access to care. Periodontal disease involves inflammation and destruction of the tissues that support teeth, starting with gingivitis and potentially progressing to periodontitis with loss of bone and connective tissue. It is also highly prevalent, especially as people age, and is driven by plaque biofilm along with risk factors like smoking and systemic health conditions. These two are more common than the other listed conditions: tooth fractures are less frequent as a population-wide disease; halitosis is usually a symptom rather than a disease; fluorosis is a localized enamel defect and not as widespread; malocclusion is a structural condition rather than a disease, and pulpitis is typically a result or complication rather than a broadly prevalent disease on its own. So the best answer highlights the two most common, impactful, and preventable chronic dental diseases: dental caries and periodontal disease.
