Diabetes and Oral Health: Understanding the Connection
The mouth is an important part of overall health but is often overlooked when discussing complications associated with diabetes. Diabetes can have a serious impact on your oral health and increase your risk of several dental conditions.
Common Oral Health Problems Linked to Diabetes
1. Periodontitis
Periodontitis or gum disease, is the most common oral complication related to diabetes. It causes gum and bone recession around the teeth, leading to loose, painful, or lost teeth if left untreated. This condition is chronic and requires consistent professional care. Studies show a two-way relationship between diabetes and gum disease. Periodontitis can make it harder to manage blood glucose levels, increasing HbA1C levels and the risk of prediabetes. Professional periodontal treatment can moderately improve glycaemic control, highlighting the importance of regular dental visits. Well-controlled blood glucose, however, lowers this risk to that of non-diabetic individuals.
2. Tooth Decay
Diabetes-related gum disease can expose the tooth’s root surface, making it more susceptible to decay. Reduced saliva flow, often present in people with diabetes, also increases this risk by reducing the natural protection saliva provides.
3. Dry Mouth (Xerostomia)
A common symptom in people with diabetes is reduced saliva production, causing a persistent dry feeling in the mouth. It is more frequent in individuals with diabetic neuropathy and can lead to increased tooth decay, gum disease, and infection.
4. Oral Thrush (Candidiasis)
Oral thrush is a fungal infection that appears as white patches in the mouth or on the tongue. High blood sugar, reduced saliva, and a weakened immune system increase the likelihood of this infection in diabetes patients.
5. Delayed Wound Healing
Changes in blood flow and reduced immunity can cause delayed or poor healing of mouth ulcers and other oral wounds, making it harder for the body to recover from even minor injuries.
6. Altered Taste
Diabetes can affect the ability to taste food and drinks, possibly because of slower cell renewal in taste receptors or nerve-related complications.
Recognising Symptoms of Gum Disease
Early signs of periodontal disease include:
-
Bleeding gums
-
Bad breath
-
Gum recession and longer-looking teeth
-
Tooth sensitivity or looseness
-
Spaces developing between teeth
These symptoms often occur without pain, which is why regular dental check-ups are essential to detect and manage problems before they progress.
Maintaining Good Oral Health with Diabetes
To reduce the risk of oral complications, follow these practical tips:
-
Brush twice daily with fluoride toothpaste and a soft toothbrush
-
Use floss or interdental brushes to clean between teeth
-
Drink fluoridated water to strengthen teeth and reduce decay
-
Chew sugar-free gum to promote saliva flow
-
Avoid smoking, which increases the risk of gum disease
-
After treating hypoglycaemia with sugary foods, rinse with water and wait 60 minutes before brushing
Dental Care for Patients with Diabetes
Dr. Daniel Kaufman plays an essential role in preventing, diagnosing, and treating diabetes-related oral health problems. Always inform Dr. Kaufman about your diabetes condition, blood glucose control, and any medications you are taking. Regular dental visits and ongoing communication can significantly improve your oral and overall health.
