Why are People with Diabetes at Higher Risk of Gum Problems?

Published on 03/01/2024

Diabetes is a chronic condition that affects millions of people worldwide, and its impact extends beyond blood sugar control. Individuals with diabetes often face an increased risk of various complications, and one such concern is the higher susceptibility to gum problems.

This is why those with diabetes need to pay close attention to their oral health and make sure they visit the dentist regularly. Pregnant women are also at risk of gestational diabetes, which also comes with an increased risk of gum problems. 

The relationship between diabetes and gum disease is intricate, and understanding the connection is crucial for effective prevention and management. If you are concerned about how your diabetes diagnosis might impact your oral health, book an appointment with your dentist to learn more.

The link between diabetes and gum disease

Before we can look at ways those with diabetes can limit their risk, let’s first look at how the two conditions are linked.

Blood sugar levels and inflammation

Elevated blood sugar levels are a hallmark of diabetes. This excess glucose in the bloodstream can lead to increased inflammation throughout the body, including the gums.

Inflammation is a key factor in the development and progression of gum disease. It can compromise the body’s ability to fight off infections, making individuals with diabetes more prone to periodontal issues.

Impaired immune response

Impaired immune response

Diabetes can compromise the immune system’s effectiveness, making it harder for the body to combat infections, including those affecting the gums.

In a weakened immune state, the gums become more susceptible to bacterial growth, leading to the development of gum disease.

Altered microbial environment

Diabetes can create an environment in the mouth that is conducive to the growth of harmful bacteria. Changes in saliva composition and increased glucose levels provide an ideal breeding ground for bacteria that contribute to gum disease.

Imbalances in the oral microbiome can lead to a shift from a healthy state to one that promotes inflammation and infection. Focusing on ways to improve the microbial environment in your mouth could help to limit the impact, and this often starts with your food choices and how you care for your teeth.

Reduced blood circulation

Diabetes can impact blood vessel function, leading to reduced blood circulation. This diminished blood flow affects the ability of the gums to receive essential nutrients and oxygen.

This is particularly challenging because it can not only cause gum problems, but it can also impact your ability to treat gum problems. Low blood flow to the gums can impact the body’s ability to heal and regenerate tissues, making it challenging for individuals with diabetes to recover from gum problems.

How to manage diabetes and gum disease

How to manage diabetes and gum disease

It might sound like gum disease is an inevitable outcome for those with diabetes, but this isn’t the case. With increased awareness of the impact diabetes can have on your gum health, there are steps you can take to limit the impact.

Education and support is essential for those living with diabetes to help limit the wider impact on their health. Your dentist and dental hygienist will play a vital role in guiding you through this process and ensuring that your diabetes doesn’t impact your wider oral health.

Here are just some of the ways you can manage the impact of diabetes on your gum health:

Keep blood sugar levels under control

Maintaining optimal blood sugar levels is paramount for preventing and managing gum problems in individuals with diabetes. Regular monitoring and adherence to prescribed medications or insulin therapy are essential.

If you are struggling to manage your diabetes, visit your GP first. Getting on top of your diabetes management will be a positive first step towards taking control of your oral health. You can then visit your dentist for bespoke advice on how to limit the impact on your gum health.

Be diligent about oral hygiene

Be diligent about oral hygiene

Brushing and flossing regularly help remove plaque, the primary culprit in gum disease. People with diabetes should be particularly diligent in their oral hygiene routines.

Every mouth is different, and the spacing between your teeth will have a huge impact on how you brush and floss. Your oral health requirements can also change as you get older, so make sure you ask for updated advice if there are any major changes to your teeth and gums.

A trip to the dental hygienist is an ideal opportunity to ask questions about how you can improve your oral health routine.

Attend regular checkups

Regular dental check-ups are crucial for individuals with diabetes. Dentists can monitor oral health, detect early signs of gum disease, and provide tailored advice for preventive care. We often only notice issues with our teeth when there is a problem, and this is usually indicated by pain. Unfortunately, waiting until we are in pain can be damaging, as this is often a sign that a small issue has become a much bigger problem.

Small lifestyle changes

Small lifestyle changes

Adopting a healthy lifestyle, including a balanced diet and regular exercise can have a positive impact on your diabetes management and your wider oral health. If you are a smoker, making the often difficult decision to quit can be life-changing.

Smoking can further aggravate gum disease caused by diabetes by drying out your mouth. Dry mouth can allow bacteria to multiply freely, which can make gum disease much worse.


The intricate relationship between diabetes and gum problems underscores the importance of comprehensive care. Individuals with diabetes should prioritise both their general and oral health to help limit the risks of developing gum disease. Education and proper support from your dental team are essential to combating the wider health implications of diabetes.

By understanding the interplay between diabetes and oral health, individuals can take proactive steps to prevent and manage gum problems, promoting overall well-being and a healthier smile.
