The Short Answer: Diabetes affects dental health primarily by lowering your body’s resistance to infection and slowing down the healing process.
High blood glucose levels can cause blood vessels to thicken, reducing the flow of nutrients and oxygen to the gums. This makes people with diabetes significantly more prone to periodontal (gum) disease, dry mouth, fungal infections, and tooth decay.
Why are people with diabetes more prone to gum disease?
This is the most common question we hear. The link comes down to how your body handles bacteria. Your mouth is naturally full of bacteria. Usually, your body’s immune system keeps them in check. However, diabetes can weaken your white blood cells, which are the body’s main defence against bacterial infections. When you combine a lowered immune response with poor blood flow to the gums, the bacteria in plaque can cause inflammation much faster than normal. This is why gingivitis (early gum disease) can turn into periodontitis (severe gum disease) more quickly in patients with diabetes.
Can poor oral health affect my blood sugar?
Yes, the relationship is a “two-way street.” While diabetes increases the risk of gum disease, severe gum disease can actually make your diabetes harder to manage. Active gum disease is an infection that creates inflammation throughout the body. This inflammation can impair your body’s ability to utilise insulin effectively, which may cause your blood sugar levels to rise. Treating gum disease can often help improve blood glucose control.
What are the specific oral symptoms of diabetes?
Beyond gum disease, diabetes can manifest in your mouth in several ways:
- Dry Mouth (Xerostomia): Diabetes can reduce saliva flow. Since saliva protects teeth from acid, a dry mouth increases the risk of cavities.
- Oral Thrush: High glucose levels in your saliva provide food for the fungus Candida, leading to white patches (thrush) in the mouth.
- Slow Healing: You may notice that sores, cuts, or dental treatments (like extractions) take longer to heal than usual.
- Burning Mouth Syndrome: Some patients experience a burning sensation in the mouth or tongue.
How can I protect my teeth if I have diabetes?
Managing your dental health is a crucial part of managing your diabetes.
- Control Your Blood Sugar: The better your glucose control, the lower your risk of oral complications.
- Brush and Floss Daily: removing plaque is your best defence against infection.
- Tell Your Dentist: When you visit us at Sundial Dental, let us know you have diabetes and provide an update on your condition.
- Regular Cleans: Because you are more susceptible to tartar buildup, professional cleans are essential to keep inflammation down.
