What is the relation between diabetes control and periodontal disease?

• A. Poorer diabetes control worsens periodontal disease and vice versa
• B. No relationship
• C. Diabetes only affects tooth loss
• D. Periodontal disease improves diabetes control

Answer: (A)

The key idea is that the link between diabetes control and periodontal disease goes both ways. When diabetes is not well controlled and blood glucose stays high, the immune system doesn’t work as well, healing is slower, and inflammatory processes in the gums are amplified. This makes periodontal disease more likely to flare up and become more severe.

In turn, periodontal disease isn’t just a local mouth problem. The inflammatory mediators released from inflamed periodontal tissues can enter the bloodstream and contribute to systemic inflammation, which can worsen insulin resistance and make blood glucose harder to control. In some people, addressing periodontal disease can lead to modest improvements in glycemic control, while keeping diabetes well-managed generally supports better periodontal health.

So the best answer reflects this two-way relationship: poorer diabetes control can worsen periodontal disease, and periodontal disease can influence diabetes control.
