Oral health is often described as a mirror of general health. Yet despite being both preventable and treatable, oral diseases remain some of the most widespread health conditions globally.
According to a report this year from the World Health Organization (WHO), nearly 3.7 billion people (almost half the global population) are affected by oral diseases, from untreated tooth decay to gum disease, tooth loss, and oral cancers.
The consequences extend beyond discomfort. Poor oral health can affect nutrition, speech, confidence, employability, and overall wellbeing, turning dental care access into a public health challenge with far-reaching implications.
So, what can be done? In this article, we explore how postgraduate dental education can help with this issue, giving dentists across the globe the skills, resources, and support to make dental treatment available to those in their communities.
Poverty and Dental Care
Before we get into exploring solutions, let’s first turn our attention to the challenge itself.
There is a strong link between poverty and oral health outcomes. WHO data shows that three out of four people with oral diseases live in low- and middle-income countries, where prevention and treatment services are limited. Even in higher-income nations, people on lower incomes, those living with disabilities, or older adults in care often experience worse oral health.
The most common conditions tied to inequality include:
- Untreated caries (tooth decay), affecting 2.5 billion people worldwide, and the single most common health condition according to the Global Burden of Disease project.
- Severe gum disease, which impacts around 1 billion people, often leading to tooth loss.
- Edentulism (total tooth loss), which affects nearly one in four older adults globally, with significant effects on quality of life.
These outcomes reflect gaps in access to care, because of affordability issues, limited prevention programmes, and a lack of professional education.

Global Trends in Oral Health
The prevalence of oral diseases has increased by over 1 billion cases in the last 30 years. Much of this growth is linked to changes in diet and lifestyle, including high sugar consumption, tobacco use, and alcohol intake.
At the same time, access to prevention and treatment remains uneven. Oral health services frequently rely on out-of-pocket payments, creating a significant financial burden for families. In many health systems, oral care is still not included in universal health coverage benefit packages.
This combination of rising risk factors and limited access contributes to widening inequalities in oral health, with those most in need often receiving the least support.
The Role of Education in Tackling Dental Care Inequality
One important way to address dental care inequality is through education. Skilled dentists can play a vital role in improving access by expanding the treatments available within their local communities.
For example:
- Training in orthodontics can help retain patients who might otherwise be referred away.
- Education in aesthetic and restorative dentistry can support comprehensive treatment planning and long-term oral health improvements.
- Postgraduate training in implantology and oral surgery can give patients access to fixed solutions that transform daily function and quality of life.
By providing dentists with advanced skills, education can create a ripple effect; raising the standard of care and improving outcomes for patients far beyond the individual practice.
At the London Dental Institute, our mission is to make this kind of postgraduate education accessible globally. By delivering diplomas entirely online, supported by mentoring, case-based learning, and practical resources, we aim to reduce the barriers that have historically limited access to specialist training.
Continuing our Mission
Dental care inequality is one of the most pressing challenges in global health today. With billions affected, and cases continuing to rise, the need for prevention, treatment, and professional training is clear.
Education is not the only solution, but it plays a vital role. By equipping dentists with the skills and confidence to deliver advanced treatments in their own communities, we can begin to narrow the gap and make quality care more widely available.
At LDi, we remain committed to supporting this mission: to make high-quality postgraduate dental education accessible wherever dentists live and practise. Read more here.
