Diabetes and Gum Disease: How Blood Sugar Hurts Teeth

Have you ever wondered why your gums bleed more when your blood sugar is high? It feels like a small problem, but it could be a sign of something bigger.

People with diabetes are three times more likely to get gum disease, according to the American Dental Association (ADA).

And here’s the twist: Gum problems can make your blood sugar harder to control. What if fixing your gums could help your whole health? Keep reading to learn the simple facts, see a helpful chart, and get easy steps to fight back. Your smile – and your body – will thank you.

The Two-Way Problem: Diabetes and Gum Disease Work Against Each Other

Diabetes makes it tough for your body to fight germs. High blood sugar helps bad bacteria grow in your mouth. This leads to gingivitis, which is red and sore gums. If not treated, it turns into periodontitis. This eats away at the bone holding your teeth.

The other way around? Sore gums send signals that make insulin work less well. This can raise your HbA1c score by 0.4% or more. The ADA says ignoring this raises risks for heart trouble. It’s a cycle, but you can stop it.

How High Blood Sugar Hurts Your Teeth and Gums

Too much sugar in your blood dries out your mouth. Saliva normally washes away germs. Without it, acids attack your teeth. Your body’s germ fighters get confused and cause too much swelling. This makes deep pockets around teeth, leading to loose teeth or infections. If your HbA1c is over 7%, your chance of bad gum disease triples.

HbA1c and Gum Disease: See the Link in This Chart

Tests show the more your HbA1c goes up, the worse your gums get. One big ADA study found that cleaning gums well can lower HbA1c by up to 0.9% for people with type 2 diabetes. Look at this chart from expert reviews. It shows HbA1c levels next to gum damage (called CAL, or how much gum sticks to teeth).

HbA1c Level (%)	Gum Damage Level (CAL in mm)	Extra Risk
Under 6.5 (Good Control)	1-2 (Light)	Normal
6.5-8.0 (Fair)	3-4 (Medium)	2 Times Higher
Over 8.0 (Poor Control)	Over 5 (Severe)	3-5 Times Higher

This chart makes it clear: Better sugar control means healthier gums.

Warning Signs: Is Diabetes Hurting Your Gums?

Watch for these clues:

• Bad breath that won’t go away or a funny metal taste.
• Gums that are red, puffy, or bleed when you brush.
• Teeth that feel loose or gums pulling back.
• Sores in your mouth that heal slowly.

If you see two or more, act fast. People with diabetes should see the dentist twice a year, or more if needed.
