How Your Dentist Near Me Can Now Screen for Diabetes: A Revolutionary UK Healthcare Approach

Did you know that approximately one million people in the UK are living with undiagnosed Type-2 diabetes? That's one million individuals going about their daily lives, unaware of a condition that could be silently damaging their bodies. What's particularly striking is that many of these people regularly visit their dentist, even if they rarely see their GP.

This presents a unique opportunity for dental professionals like myself to play a crucial role in early detection and intervention. Let's explain how your routine dental visit could now potentially save your life through this innovative screening approach.

Key Takeaways

1. Silent Epidemic: Approximately one million people in the UK are living with undiagnosed Type-2 diabetes, and dental practices offer a unique opportunity for early detection.

2. Bidirectional Relationship: There's a two-way relationship between diabetes and oral health – diabetes increases the risk of gum disease, while severe gum disease can make diabetes harder to control.

3. Evidence-Based Approach: The INDICATE study found that almost 15% of UK dental patients exceeded pre-diabetes/diabetes thresholds, demonstrating the effectiveness of dental screening.

4. Simple Screening Process: Dental diabetes screening involves a straightforward questionnaire and finger-prick blood test that can be completed during a routine dental appointment.

5. Integrated Care: The future of healthcare in the UK is moving toward better integration between dental and medical services, with diabetes screening representing an important step in this direction.

   
   

The UK Diabetes Crisis: A Growing Concern

The statistics surrounding diabetes in the UK are sobering. Over 5 million people in the UK are living with diabetes – that's more than 1 in 14 people. According to Diabetes UK, an estimated 12.1 million adults in the UK are living with diabetes or pre-diabetes.

What's particularly alarming is the rate at which these numbers are growing. Recent reports show an almost 40% increase in just 5 years in the number of people diagnosed with type 2 diabetes in the UK. Between 2023 and 2024 alone, over 3.5 million people in England were registered with type 2 diabetes, while almost 277 thousand had type 1.

The UK now has the second highest prevalence of diabetes in the G7, with approximately 8% of the population affected, projected to rise to 10% in the coming years. The NHS has identified over half a million more people in England as being at risk of developing type 2 diabetes in a single year, highlighting the scale of this public health challenge.

The consequences of undiagnosed and untreated diabetes are severe – from cardiovascular disease and kidney failure to vision loss and nerve damage. Early detection and management are crucial to preventing these complications, which is precisely where dental practices can make a significant difference.

The UK Dental Landscape: Uniquely Positioned for Screening

The UK dental market comprises approximately 12,344 dental practices and is estimated to reach £10.6 billion in 2024. What many people don't realise is that 65% of these practices are owned by independent single or dual practitioners, rather than large corporate chains.

This independent structure often allows for more flexibility in implementing innovative approaches to patient care, such as diabetes screening. However, it's worth noting that only 15% of dental practices in the UK are fully NHS, with the majority being either private or offering a mix of NHS and private services.

This shift in the dental market creates both challenges and opportunities for implementing diabetes screening. As a dental professional, I've observed that private practices often have more flexibility to introduce new services, while NHS practices may need to work within commissioning frameworks to implement screening programmes.

Regardless of practice type, UK dentists are uniquely positioned to identify patients at risk of diabetes for several reasons:

1. Regular contact: Many people see their dentist more regularly than their GP, particularly if they're feeling well.

2. Oral manifestations: Diabetes often presents with oral symptoms that dentists are trained to recognise.

3. Established relationship: The ongoing relationship between dentists and patients creates trust and continuity of care.

4. Preventive focus: Dental care is increasingly focused on prevention rather than just treatment.

The Mouth-Body Connection: Why Your Dentist Can Spot Diabetes

The connection between oral health and diabetes is bidirectional and well-established in medical literature. The International Diabetes Federation and European Federation of Periodontology have set out a clear roadmap for the co-morbid relationship between periodontitis (severe gum disease) and type 2 diabetes. These recommendations have been reinforced by the National Institute for Health and Care Excellence (NICE) guidance on management of diabetes.

Here are some observations on how diabetes affects oral health:

• Periodontal disease: People with diabetes are three times more likely to develop severe gum disease. Conversely, severe gum disease can make blood glucose levels more difficult to control.

• Delayed healing: Patients with uncontrolled diabetes often experience slower healing after dental procedures.

• Dry mouth: Reduced saliva flow, a common symptom of diabetes, increases the risk of tooth decay and oral infections.

• Oral infections: Fungal infections like thrush are more common in people with diabetes.

• Burning mouth syndrome: Some diabetic patients experience a burning sensation in their mouth.

What's particularly significant is that periodontal disease is often one of the earliest complications of diabetes. This means that as dentists, we may be the first healthcare professionals to observe signs of undiagnosed diabetes, even before other symptoms become apparent to the patient or their GP.

Effective treatment of periodontitis in people with type 2 diabetes can improve glycaemic control to an extent that can reduce the need for additional medication. This highlights the importance of integrated care between dental and medical professionals.

The INDICATE Study: Groundbreaking UK Research

The University of Birmingham has been at the forefront of research into dental diabetes screening in the UK. In a study published in 2023, researchers developed a new score called the Diabetes risk assessment in Dentistry Score (DDS), specifically designed for use by dental teams to detect pre-diabetes and diabetes.

As part of the INDICATE pilot study, funded by the National Institute for Health and Care Research (NIHR) and Diabetes UK, the DDS was used alongside a finger-prick HbA1c test. The results were eye-opening: almost 15% of people who walked into dental practices believing themselves to be healthy exceeded UK pre-diabetes/diabetes thresholds.

This research has now expanded into the INDICATE-2 study, with 38 practices across England already recruited and plans to include practices in Northern Ireland, Wales, and Scotland. The study has received funding from Haleon (the global consumer health company behind brands like Sensodyne and Corsodyl) and continued support from the NIHR.

I've spoken with colleagues participating in this research, and they report positive feedback from patients who appreciate this additional dimension of care. One such patient is Ann Christian, a 50-year-old from Birmingham, whose story exemplifies the potential of this approach.

During a routine dental check-up, Ann's dentist noticed signs of severe gum disease and suggested a blood glucose test. The test revealed alarmingly high blood sugar levels, despite Ann believing her diabetes was being well-controlled through diet alone. This discovery led to proper medical intervention, including medication, which significantly improved both her diabetes control and her oral health.

As Ann herself said: "I really do think it's an excellent idea to have dental teams help to identify patients who are at risk of diabetes or who already have diabetes but they're not controlling it in the best way. I've always felt that medical care can be too pigeon-holed. I think this is a fantastic way to improve people's health in general."

How Dental Diabetes Screening Works in UK Practices

The screening process in UK dental practices is straightforward and minimally invasive. Here's what you can expect if your dentist offers this service:

1. Risk assessment questionnaire: You'll complete a validated questionnaire (the DDS) that assesses your risk factors for diabetes. This includes questions about your age, family history, lifestyle, and any symptoms you might be experiencing.

2. Oral examination: Your dentist will conduct a thorough examination of your mouth, paying particular attention to signs that might indicate diabetes, such as severe gum disease, multiple dental abscesses, or slow healing from previous treatments.

3. Finger-prick blood test: If the questionnaire and examination suggest you might be at risk, a simple finger-prick test will measure your HbA1c level. This indicates your average blood glucose levels over the past 2-3 months.

4. Results and referral: If your HbA1c level is 42 mmol/mol or higher (the UK threshold for pre-diabetes), your dentist will refer you to your GP for formal diagnosis and appropriate management.

It's important to understand that dental professionals do not diagnose diabetes – this remains the responsibility of medical doctors. Our role is to identify those at risk and facilitate timely referral to appropriate medical care.

The test takes just a few minutes during your regular dental appointment and could potentially save you years of undiagnosed diabetes progression. As a dental surgeon, I've found that patients appreciate this holistic approach to their health, seeing it as an added value to their dental visit rather than an intrusion.

Finding a UK Dentist Who Screens for Diabetes

If you're interested in accessing diabetes screening at your dental practice, here are some practical steps to find a provider:

1. Ask your current dentist: Start by inquiring whether your existing dental practice offers diabetes screening. Many practices participating in the INDICATE-2 study are already implementing this service.

2. Check practice websites: Forward-thinking dental practices often highlight additional services like diabetes screening on their websites or social media pages.

3. Contact local dental networks: Your local dental network or Local Dental Committee may have information about practices offering screening in your area.

4. NHS vs private considerations: While both NHS and private practices may offer screening, it's currently more common in private or mixed practices. However, as the evidence base grows, more NHS practices may incorporate screening into their services.

When contacting a dental practice, ask specific questions such as:

• "Do you offer diabetes screening as part of your routine check-ups?"

• "Is there an additional cost for diabetes screening?" (This varies by practice)

• "What is your referral process if the screening indicates I might be at risk?"

Remember that while the screening itself is valuable, the most important aspect is the pathway for follow-up care if your results indicate potential diabetes.

The Benefits of Early Detection in the UK Context

Early detection of diabetes through dental screening offers numerous benefits, both for individual patients and for the NHS as a whole:

For patients:

• Earlier intervention can prevent or delay serious complications

• Improved quality of life through proper management

• Better oral health outcomes when diabetes is controlled

• Potential reduction in medication needs through early lifestyle changes

• Integrated care that addresses both oral and systemic health

For the NHS:

• Reduced burden of treating advanced diabetes complications

• More efficient use of healthcare resources

• Decreased hospital admissions for diabetes-related emergencies

• Lower long-term treatment costs

• Better population health outcomes

Research suggests that the cost of treating diabetes complications far exceeds the cost of early intervention. By identifying at-risk patients in the dental setting, we can potentially save the NHS millions of pounds while improving patient outcomes.

The Future of Dental-Medical Integration in the UK

The integration of diabetes screening into UK dental practices represents just the beginning of a broader trend toward medical-dental integration. The NHS Long Term Plan explicitly recognizes the importance of joined-up care, and dental practices are increasingly seen as valuable partners in this approach.

Dr. Jason Wong MBE, Chief Dental Officer for England, has stated: "It is vitally important that medical and dental care pathways become more joined up, to put patients at the centre of all we do. INDICATE-2 is a great example of a study aimed to try and define one such pathway."

Looking ahead, we can anticipate several developments:

1. Expanded screening programmes: As evidence continues to mount, diabetes screening may become a standard part of dental care across the UK.

2. Additional health screenings: Beyond diabetes, dental practices may begin screening for other conditions with oral manifestations, such as cardiovascular disease or sleep apnoea.

3. Enhanced digital integration: Improved sharing of patient information between dental and medical records will facilitate more coordinated care.

4. Workforce development: Dental professionals will receive more training in recognizing and addressing systemic health conditions.

5. Policy changes: NHS commissioning frameworks may evolve to support and fund screening activities in dental settings.

As a dental surgeon committed to comprehensive patient care, I believe this integration represents the future of healthcare – one where artificial divisions between different aspects of health are replaced by a more holistic, patient-centered approach.

Conclusion

The ability of UK dental practices to screen for diabetes represents a significant advancement in preventive healthcare. With approximately one million people living with undiagnosed diabetes in the UK, and many more at risk of developing the condition, this approach has the potential to transform lives through early detection and intervention.

As a patient, It is encouraged for you to ask your dentist about diabetes screening at your next check-up. If they don't currently offer this service, expressing interest may encourage them to consider implementing it.

By bridging the gap between dental and medical care, this can provide truly comprehensive healthcare that addresses both oral and systemic health. After all, the mouth is not separate from the body, and the approach to healthcare shouldn't be treated as such.

Frequently Asked Questions

1. Is dental diabetes screening covered by the NHS?

Currently, diabetes screening is not universally covered under NHS dental contracts. Some NHS practices may offer it as part of research studies like INDICATE-2, but it's more commonly available in private practices or as an additional service with a separate fee. As evidence for its effectiveness grows, there may be changes to NHS commissioning to support wider implementation.

2. How accurate is diabetes screening at UK dentists?

The screening approach used in UK dental practices combines a validated risk assessment questionnaire with a finger-prick HbA1c test. This combination provides good accuracy for identifying those at risk. The HbA1c test used is the same type used in medical settings. However, it's important to remember that dental screening is not a diagnosis – positive results require follow-up with a GP for formal diagnosis.

3. How often should I get screened for diabetes at my dental visits in the UK?

For most adults without known risk factors, screening every 1-2 years is reasonable. However, those with risk factors such as family history of diabetes, obesity, history of gestational diabetes, or signs of periodontal disease may benefit from annual screening. Your dentist can advise on the appropriate interval based on your individual risk profile.

4. Can children be screened for diabetes at dental appointments in the UK?

Dental diabetes screening is primarily focused on adults, particularly those over 45, as Type 2 diabetes is more common in this age group. However, with rising rates of Type 2 diabetes in younger populations, some practices may offer screening to younger adults with risk factors. Type 1 diabetes, which is more common in children, typically presents with more acute symptoms and is usually diagnosed in medical settings.

5. What's the difference between screening at an NHS dentist vs. a private practice?

The screening process itself is similar in both settings, using the same risk assessment tools and HbA1c testing. The main differences relate to cost and availability. Private practices may have more flexibility to offer screening as a standard service, while NHS practices may be more constrained by commissioning arrangements. Additionally, private practices might offer more comprehensive follow-up support or integration with other health services.
