Structural imbalance in Spain’s dental workforce: public capacity and private dependence

Background

Oral diseases are highly prevalent and socially patterned, yet Spain lacks centralized data on the regional distribution of its public dental workforce.

Objectives

To provide the first systematic, multi-source analysis of Spain’s dental workforce across the 17 Autonomous Communities and Ceuta and Melilla, distinguishing salaried public dentists, privately accredited providers in publicly funded programmes, and total registered professionals, and to quantify inter-regional variation in public-sector capacity and dependence on private provision.

Methods

Cross-sectional comparative study based on transparency requests to all 19 administrations, supplemented by official registration, population, and Ministry of Health data. Indicators included total dentists, salaried public dentists, and privately accredited providers per 100,000 inhabitants, plus the public/total ratio, population load per public dentist, and a Structural Dependence Index (SDI).

Results

In 2024–2025, Spain had 42,860 active dentists (84.68/100,000) but only 1,685 salaried public dentists (3.36/100,000; 31,590 inhabitants per dentist). The public/total ratio ranged from 2.0% in Madrid to 7.6% in Castilla-La Mancha, with greater inter-regional variation than total dentist density (CV 31.3% vs 24.9%). A further 6,810 privately accredited providers across 11 mixed-model regions raised the public-system workforce to 8,495 professionals (17.21/100,000). SDI ranged from 0% in eight purely public regions to 95.4% in País Vasco; nine of eleven mixed-model regions exceeded 80%.

Conclusions

Spain’s oral health challenge is not a shortage of professionals but a structural imbalance between an abundant private workforce and an understaffed public dental system. Territorial inequity is driven more by distribution than by aggregate supply. Reform should begin with a national dental workforce registry, an oral health observatory, and workforce planning targets aligned with primary care standards.

Key messages

• Spain does not face a shortage of dentists, but a structural imbalance: a large private workforce coexists with a chronically understaffed public dental system.

• Regional inequity in oral health access is driven by weak public capacity and heavy reliance on private providers, not by overall workforce supply.
