If you have done any dental nursing training, sat any exams, or completed any post-registration qualifications, you will have come across the phrase Delivering Better Oral Health. It gets referenced constantly. But not everyone has actually sat down and read it, and even fewer could explain what it really means for their day-to-day practice.
This post is a plain-English overview of what DBOH is, what it covers, and why it matters specifically for dental nurses.
Delivering Better Oral Health, usually abbreviated to DBOH, is an evidence-based toolkit for prevention published jointly by the Department of Health and Social Care, NHS England, the Welsh Government and the Department of Health Northern Ireland. It has been developed with the support of all four UK Chief Dental Officers.
It was first published in 2007 and has been updated several times since. The current version, the fourth edition, was last updated in September 2025.
The primary audience is dental teams providing frontline care. It is designed to support dental professionals in routinely promoting oral health and preventing oral disease, drawing on a UK-wide collaboration of well-respected experts including frontline dental teams and patient representatives.
DBOH covers four main oral diseases:
For each of these it provides evidence-based recommendations on prevention, organised into summary tables in Chapter 2. These tables set out what advice and clinical interventions should be offered to all patients, and what additional support should be provided for those at higher risk.
Beyond the disease-specific chapters, DBOH also covers:
This is worth understanding properly because it affects how you interpret and apply the guidance.
DBOH uses the GRADE system to classify its recommendations. Each recommendation is rated based on the quality of the evidence behind it:
Strong recommendations mean the evidence clearly supports the intervention. The guidance development group is highly confident that the benefits outweigh any risks.
Conditional recommendations mean the evidence is less certain, or the balance between benefits and risks is less clear. A conditional recommendation does not mean the intervention does not work. It means the current evidence is not of the highest certainty.
Good practice points are based on clinical consensus and expert opinion rather than research directly rated for certainty. They reflect established clinical practice.
Understanding this matters because it helps you explain to patients why you are recommending something, and it helps you understand the difference between what is firmly evidence-based and what is based on clinical consensus.
DBOH is not just for dentists. It is for the whole dental team. The guidance specifically states it supports primary care dental teams to routinely promote oral and general health, and it is an educational resource for dental schools and postgraduate training providers.
For dental nurses this means DBOH is relevant to your practice every time you give oral health advice, apply fluoride varnish, discuss diet with a patient, or support a patient with behaviour change around their oral hygiene.
One of the most important principles running through DBOH is that care and advice should be tailored to each patient’s individual risk. The guidance is clear that each patient’s risk needs to be assessed at every dental recall visit and monitored across the life course, because disease risk will change over time.
Patients considered to be giving concern, meaning those at higher risk of dental disease or for whom disease would present a significant challenge, include:
This risk-based framework is directly relevant to fluoride varnish application. When you assess a patient’s caries risk before treatment, review their care plan, and decide on the frequency of application, you are applying the DBOH risk-based approach in practice. For a full guide to the clinical steps involved, read our post on how to apply fluoride varnish.
There are a few practical reasons why DBOH matters beyond just passing exams.
It underpins your clinical decision-making. When you apply fluoride varnish, assess a patient’s diet, or give oral hygiene advice, DBOH is the evidence base behind those recommendations. Knowing where the guidance comes from makes you a more confident and more credible clinician.
It supports your conversations with patients. Being able to explain why you are recommending something, and how the advice is based on research rather than personal opinion, helps patients understand and act on what you are telling them.
It is referenced throughout post-registration training. Whether you are completing a fluoride varnish qualification, a radiography course, or an oral health education programme, DBOH will come up. Understanding it properly rather than just knowing its name makes a real difference to the quality of your written work and your practical assessments.
It is a living document. DBOH is updated regularly as new evidence emerges. Keeping up with changes is part of your professional development as a dental nurse and contributes to your GDC CPD requirements. For a full guide to what CPD requires, read our post on CPD requirements for dental nurses.
DBOH is freely available on GOV.UK. You can read the full guidance including all chapters and summary tables at:

Chapter 2, the summary guidance tables, is the most practically useful starting point if you want to understand how the recommendations apply to specific patient groups.
If fluoride varnish application is part of your practice or something you are working towards, DBOH is essential reading. Our course covers it in depth alongside GDC scope of practice, clinical technique and documentation. Find out more here.
DBOH also underpins many of our other post-registration courses. Explore the full range of courses at Dental Nurse Training.
Dental Nurse Training offers a full range of GDC-recognised courses and qualifications, from the Level 3 Diploma in Dental Nursing through to post-registration qualifications in fluoride varnish application, radiography, oral health education and beyond.
