Why do dentist ask if you have diabetes?


Diabetes is a complex disease that can impact many aspects of a person’s health, including oral health. When you visit the dentist for a check-up or procedure, one of the standard health history questions you’ll be asked is “Do you have diabetes?” There are very good reasons for dentists to screen patients for diabetes. Understanding why this question is asked can help you appreciate the interconnected relationship between oral health and overall wellness.

Diabetes Overview

Diabetes mellitus refers to a group of metabolic disorders characterized by high blood sugar levels over a prolonged period of time. There are a few different types of diabetes:

  • Type 1 diabetes – An autoimmune disease where the pancreas stops producing insulin. It usually starts in childhood or young adulthood and requires insulin treatment.
  • Type 2 diabetes – The most common type, occurring when the body becomes resistant to insulin or doesn’t make enough insulin. It primarily affects adults.
  • Gestational diabetes – A temporary form of diabetes that can develop during pregnancy.
  • Prediabetes – Blood sugar levels are higher than normal but not high enough for a diagnosis of diabetes. Without lifestyle changes, prediabetes often progresses to type 2 diabetes.

In the United States, the CDC estimates that 37.3 million people have diabetes, with 1.5 million new cases diagnosed every year. Undiagnosed diabetes is also a major problem, with nearly 8 million Americans estimated to have the disease but not know it.

Diabetes Can Negatively Impact Oral Health

Diabetes affects the body’s ability to process sugars. When blood sugar is chronically elevated, it can wreak havoc on many parts of the body, including the mouth. Some examples of how poorly controlled diabetes influences oral health include:

  • Increased risk of gum disease – High blood sugar creates an environment favorable to bacterial growth, infection, and inflammation.
  • Impaired wound healing – Spikes in blood glucose can hinder the body’s ability to heal mouth wounds and sores.
  • Higher rates of tooth decay – Dry mouth and increased glucose levels in saliva raise the risk for cavities.
  • Oral fungal infections – A weakened immune system makes fungal overgrowth more likely.
  • Taste impairment – Uncontrolled diabetes can damage taste nerves and alter food preferences.

In essence, the diabetic condition produces changes in the oral environment that allow bacteria to thrive and hamper the body’s natural defenses. Patients with diabetes are generally more prone to periodontal disease, thrush, mouth ulcers, and other issues. Proper glycemic control can help reduce complications.

Oral Infections Can Worsen Diabetes

While diabetes promotes oral health problems, the relationship goes both ways. Oral infections and inflammation may conversely have an adverse effect on diabetes. For example:

  • Periodontal disease is linked with poorer blood sugar control. Treating gum disease may help improve A1c levels (a measure of blood glucose over 3 months).
  • Dental abscesses and infections raise systemic inflammation. This can potentially aggravate insulin resistance and complicate diabetes management.
  • Stress from dental pain, tooth loss, or oral surgery can impact blood sugar levels.

Given this two-way association between diabetes and oral disease, managing one can positively influence the other. Dentists and physicians may need to collaborate to optimize health outcomes.

Dentists Screen for Undiagnosed Diabetes

Oral signs and exam findings may in some cases provide early clues about diabetes in patients who have not yet been diagnosed. Increased thirst, dry mouth, unexplained weight loss, mouth infections, or slow healing all warrant a closer look. Dentists can sometimes spot these red flags even before primary care doctors.

Asking about a patient’s diabetic status provides valuable medical background. A “yes” answer signals the need for special precautions and treatment considerations. A “no” reply indicates that further diabetes testing may be prudent if risk factors are present. Dental visits represent opportunities to identify undiagnosed diabetes and get patients into appropriate care sooner.

Special Care is Needed for Diabetic Patients

Knowing a patient has diabetes allows dentists to provide tailored treatment to achieve the best oral health outcomes. Some examples of customized care include:

  • Careful monitoring for periodontal disease and prompt treatment when needed.
  • Prescribing antibiotic coverage before invasive procedures if indicated.
  • Coordinating extensive dental treatment with the patient’s physician to optimize diabetes medication dosing and timing.
  • Avoiding certain medications that may interact with diabetes drugs.
  • Using localized anesthesia with epinephrine cautiously.
  • Paying close attention to signs of impaired healing after procedures.
  • Counseling patients to properly manage diabetes and control blood sugar.

With appropriate planning and precautions, even complex dental work can be performed safely on most people with diabetes. Asking about diabetes status helps dentists provide the highest standard of individualized care.

The Dental Team Plays a Role in Diabetes Education

Dentists and hygienists have frequent contact with patients at regular check-up intervals. This offers many touchpoints to provide ongoing diabetes education, motivation, and support. Dental teams can:

  • Reinforce the importance of controlling blood sugar, taking medications as prescribed, and sticking to treatment plans.
  • Explain how oral health impacts diabetes and vice versa.
  • Help patients understand symptoms of high and low blood sugar.
  • Ensure patients recognize dental complications of poorly controlled diabetes.
  • Monitor at-risk areas of the mouth and update patients on their oral health status.
  • Make further referrals to physicians, diabetes educators, dietitians, or eye doctors as needed.

By asking about diabetes, dentists can provide counseling that complements the medical care patients receive from other providers. This multidisciplinary approach helps improve outcomes.

Dentists Share Information with Medical Providers

With the patient’s consent, dentists may share relevant health information with physicians and specialists involved in the person’s diabetes care. This facilitates coordinated treatment planning.

For example, documenting periodontal status allows physicians to factor gum disease into overall diabetic control efforts. In turn, physicians may share A1c values and other data to inform dental treatment modifications.

Ongoing communication between dental and medical teams is key for optimal health, especially when complex medical conditions like diabetes are involved. Simply knowing a patient’s diabetic status through screening questions facilitates this crucial collaboration.

Conclusion

Asking about a patient’s diabetic status is standard practice in dentistry because of the many interrelationships between oral health and diabetes. Key reasons dentists need to know if a patient has diabetes include:

  • Diabetes increases the risk of oral infections and dental problems.
  • Oral inflammation can potentially worsen diabetes.
  • Dental visits allow for screening to catch undiagnosed diabetes.
  • Dentists can take special precautions and adjust treatment for diabetic patients.
  • The dental team plays an adjunctive role in diabetes education and prevention.
  • Information sharing facilitates coordinated care between dentists and physicians.

In summary, the diabetes screening question asked by dentists is much more than a routine medical history item. It provides important context that allows oral health providers to offer the highest level of individualized care to each patient. Collaborative treatment between dental and medical teams ultimately gives patients with diabetes the best chance of staying healthy.
