By 2025, oral health disparities are showing up in the numbers in ways many people do not expect, from how often preventable problems happen to who is most affected. The dataset also highlights a clear mismatch between daily habits and real outcomes, especially when you compare what should be preventable with what still shows up in care. Let’s break down the key oral health statistics and see what they reveal.
Key Takeaways
- Untreated oral diseases cost global economy $298 billion yearly in treatment.
- Oral diseases cause 1.5 million DALYs per 100,000 population globally.
- Globally, 3.5 billion people are affected by oral diseases, representing nearly half of the world's population.
- Fluoride toothpaste reduces caries by 24% in children.
- Tobacco use increases risk of periodontal disease by 2-7 times.
Regular dental visits and good daily brushing can prevent many common oral health problems.
