Understanding the Link Between Gum Disease and Diabetes
August 27, 2025

If you’re one of the 34 million people in the United States with diabetes, then it’s important to be aware of the impact that it can have on your oral health. Statistics show that over a fifth of all people with Type I or Type II diabetes also have some form of gum disease. What exactly is the reason for this connection? And is there anything you can do about it? Here’s what you should know if you want to maintain a healthy smile.
How are Diabetes and Gum Disease Connected?
Simply put, diabetes can significantly increase your risk of suffering from gum disease if it isn’t properly controlled. High blood sugar levels can weaken your immune system and lead to poor blood circulation. As a result, your body will be more susceptible to infections in general. Naturally, this includes gum disease, which is an infection of the soft tissues protecting the roots of your teeth.
On top of that, diabetes can cause your body to produce less saliva, resulting in a dry mouth. Saliva plays an important role in washing away the bacteria that can cause oral health issues. If there’s less saliva in your mouth, it will give harmful bacteria a chance to thrive, creating an environment where gum disease is more likely to occur.
How Can You Avoid Gum Disease If You Have Diabetes?
Even if you have diabetes, you can reduce your chances of developing gum disease by following these simple steps:
- Maintain Good Oral Hygiene: Brushing twice a day and flossing daily can help you avoid the accumulation of plaque that can ultimately lead to gum disease. Remember to brush your teeth for a full two minutes, and pay close attention to the area around your gum line.
- Keep Your Diabetes Under Control: Diabetes will have less of an impact on your oral health if you manage it properly. Be sure to take any medications you’ve been prescribed to control your blood sugar levels, and make a point of maintaining a healthy, balanced diet.
- Visit Your Dentist Twice a Year: During a routine dental checkup, your dentist can examine your mouth for warning signs of gum disease. If they find any, they can help you take the necessary steps to address the problem before it reaches its most severe stages.
Gum disease may be a common consequence of diabetes, but it’s not an unavoidable one. As long as you’re proactive about taking care of your mouth and controlling your blood sugar levels, it’s still possible to maintain a healthy smile!
