Oral Health Statistics 2026: Verified Figures with Primary Sources
Oral health statistics 2026. Every number checked at the source.
30 statistics on caries, gum disease, sensitive teeth, the oral care market, hydroxyapatite and fluoride research, xylitol, and what people actually do with their toothbrushes. Each figure was verified against the linked primary source before it went on this page. No secondhand numbers, no rounded-up folklore.
Statistics pages usually copy each other until nobody remembers where a number came from. This one goes the other way: every statistic below links to the exact page where the figure appears, WHO fact sheets, Cochrane reviews, national oral health studies, journal papers, and the odd market report. If we could not confirm a number at its source, it did not make the page.
The global burden
How common oral disease actually is.
Oral diseases affect nearly 3.7 billion people worldwide.

The market
What the world spends on teeth.
The global oral care market is projected to reach 49.5 billion US dollars by 2028.

Hydroxyapatite
The enamel mineral in oral care.
Hydroxyapatite oral care traces to a 1972 NASA patent for repairing teeth by growing hydroxyapatite crystals.

PubMed indexes 310 results for the search term hydroxyapatite toothpaste.
A quick proxy for the size of the published research base. Count checked July 2026. Source: PubMed, National Library of Medicine (2026).
PubMed indexes 62 results for the narrower term nano-hydroxyapatite toothpaste.

In an 18-month randomized trial, 89.29% of the hydroxyapatite toothpaste group developed no new caries surfaces versus 87.36% with fluoride toothpaste, meeting the non-inferiority threshold.

Fluoride
The evidence base for the default.
The Cochrane review of fluoride toothpastes at different concentrations includes 96 studies, 85 of them covering 48,804 randomized child participants.

Notes on method
Each statistic was checked by opening the linked source and confirming the number appears there, on July 3, 2026. Primary sources were preferred everywhere: WHO publications, Cochrane reviews, EUR-Lex, national oral health studies (Germany's DMS 6, Austria's Laender-Zahnstatuserhebung, Switzerland's Obsan), and journal papers via PubMed and PMC. Two market-size figures come from commercial research publishers because no public-body equivalent exists; treat those as industry estimates. PubMed result counts change as new papers index, so both counts carry their check date. Survey figures on brushing are self-reported. This page is informational, not medical advice.
