Periodontitis and diabetes: an interaction in both directions

The connection holds in both directions. Poorly controlled diabetes encourages inflammation in the periodontium. Conversely, untreated periodontitis makes blood sugar harder to control.

Anyone with diabetes should mention it at the dental practice unprompted — and conversely tell their GP when the gums bleed.
