For Patients With Diabetes

1. Consult an endocrinologist: Schedule an appointment to assess your blood sugar control. If your glycated hemoglobin (HbA1c) is higher than 7.5%, your doctor may adjust your medications (such as insulin dosage, oral hypoglycemic agents) or diet to lower HbA1c levels. For people with type 1 diabetes, this may involve adjusting insulin infusions to maintain stable blood sugar.

2. Follow a diabetes-friendly diet: Focus on a balanced diet, reducing your intake of refined sugars, processed foods, and carbohydrates. Increase your intake of vegetables, lean protein, and healthy fats to stabilize blood sugar. Avoid sugary drinks, candy, and high-carbohydrate foods, as these can cause blood sugar spikes.

3. Monitor your blood sugar: Monitor your fasting blood sugar daily and regularly monitor your postprandial blood sugar (2 hours after meals). The goal is to keep fasting blood sugar below 8 mmolL and postprandial blood sugar below 10 mmolL. Record your blood sugar data to share with your doctor and dentist and to be prepared to adjust your medications if necessary.

4. Inform your dentist: Please inform your dentist about your diabetes history, medication list, glycated hemoglobin (HbA1c) results, and any complications (such as kidney disease or nerve damage). Your dentist may prescribe antibiotics before and after surgery to reduce the risk of infection and will closely monitor your healing—and may schedule more frequent follow-up appointments.

Global Perspectives: Access to Pre-Surgical Care for Hypertension and Diabetes

While pre-surgical control of blood pressure and blood sugar is critical, access to the care needed to achieve this control varies significantly across the globe—creating disparities in implant success rates. In high-income countries like Sweden, Germany, and Canada, most patients with hypertension or diabetes have access to primary care doctors, medications, and blood pressureblood sugar monitoring tools, making it easier to achieve pre-surgical control. Sweden, which has one of the highest implant prevalence rates in the world, has established interdisciplinary protocols for patients with chronic conditions, resulting in high success rates even for those with hypertension or diabetes.

In middle-income countries like Brazil, India, and South Africa, access to care is more limited. Many patients with hypertension or diabetes are undiagnosed, and those who are diagnosed often struggle to afford medication or regular doctor visits. In these regions, dental professionals often collaborate with local health clinics to provide basic blood pressure and blood sugar screenings, and refer patients to low-cost or free clinics for medication adjustments. For example, in India, many dental clinics partner with government health programs to provide free blood sugar testing and connect diabetic patients with endocrinologists.

In low-income countries like Ethiopia, Malawi, and Haiti, the challenges are even greater. Access to medication, monitoring tools, and specialist care is scarce, and many patients with hypertension or diabetes are unaware of their condition. In these regions, dental implants are often only accessible to a small percentage of the population, and pre-surgical control is often not possible due to limited resources. Global organizations like the WHO and International Dental Federation (FDI) are working to address these gaps, providing training for dental professionals, distributing affordable medications and monitoring tools, and advocating for integrated healthcare that connects oral health and chronic disease management.

Cultural attitudes also play a role. In some regions, there is a stigma around chronic diseases like diabetes or hypertension, leading patients to avoid seeking care. In others, patients may not understand the link between their systemic health and dental implant success, viewing pre-surgical control as an unnecessary step. Education is key to changing these attitudes—dental professionals in these regions often host community workshops to explain the importance of blood pressure and blood sugar control for implant success and overall health.
