Is Diabetes Control Important For Healthy Teeth?

Our body’s different systems are interconnected with each other and function together for healthy well being. Here what you get to know is the correlation between diabetes control and oral health, which brings us to question whether diabetes control important for healthy teeth or not? You may get surprised to hear diabetic patients pose problems to the oral cavity due to uncontrolled sugar levels and vice versa.

Why are people with diabetes more prone to dental problems? The high sugar levels may weaken the immune system as white blood cells count drops down, which results in infections.

Studies suggest that controlling blood glucose levels is important to keep all the health complications at bay. Another side is also the fact that oral health is the window of your overall health.

It is the condition (Xerostomia) when there is not enough saliva flow to keep your mouth moist. It is the diabetic medications for unstable blood glucose levels, and others are age, nerve damage, tobacco use, cancer treatments, etc.

Saliva contains the enzyme lysozyme required to attack the cell wall of bacteria, and without it, there would be uncontrolled growth. A low level of saliva secretion can further lead to ulcers, cracked or chapped lips, soreness, tooth decay, infections, dehydration, etc.

There is a strong link between diabetes and periodontal disease. But first, what is periodontal disease? Periodontal disease is the infection of gums because of plaque buildup due to bacterial growth in the mouth.

But why people with diabetes are more likely to suffer from gum infection?

Diabetes causes thickening of blood vessels, which slows down the flow of nutrients and removes waste from body tissues that lead to infection. An infection might further progress due to weakening immunity.

It hardens into tarter form if plaque is untreated. It may further cause swollen gums, redness, loose teeth, chronic bad breath, bleeding while brushing teeth, or tooth loss if surrounding tissues got damaged. Likewise, severe gum disease also affects the blood sugar level and exacerbates diabetes symptoms.

3. Burning Mouth Syndrome

So how diabetes and burning mouth syndrome are connected? People with diabetes have low immune power, so they are more susceptible to oral infections. Patients may experience the symptoms such as dry mouth, tingling on the tongue or numbness, metallic or bitter taste in the mouth.

Another indication is that medication means these drugs destroy the natural moisture from the mouth, causing decreased bacterial clearance. But additionally, these antidiabetic medicines do benefit in a way, giving pain-relieving effects.
