Diabetes and oral health are closely connected, and maintaining good dental hygiene is essential for people with diabetes.

Poor oral health can lead to complications for individuals with diabetes, making it even more crucial for them to prioritize dental care.

In this article, we will explore the relationship between diabetes and oral health, the importance of dental care, and provide tips for maintaining healthy teeth and gums for people with diabetes.

The Connection Between Diabetes and Oral Health

Diabetes is a chronic condition that affects how your body processes glucose, a type of sugar found in your blood.

When blood glucose levels are consistently high, it can cause damage to various parts of your body, including your teeth and gums.

Some common oral health problems associated with diabetes include:

  • Gum disease: Also known as periodontal disease, gum disease is an infection of the gums and bone that support the teeth. People with diabetes are at a higher risk for gum disease due to their increased susceptibility to infections [1].
  • Tooth decay: High blood glucose levels can cause an increase in the production of plaque, a sticky film that forms on your teeth. Plaque can lead to tooth decay and cavities if not removed through regular brushing and flossing [2].
  • Dry mouth: Diabetes can cause a decrease in saliva production, leading to a condition called dry mouth (xerostomia). Saliva helps protect your teeth from decay and gum disease, so having less of it can contribute to oral health problems [3].
  • Oral infections: People with diabetes are more prone to oral infections, such as fungal infections (oral candidiasis) and bacterial infections (abscesses) [4].

The Importance of Dental Care for People with Diabetes

Maintaining good oral health is vital for everyone, but it is especially important for individuals with diabetes.

Here’s why:

  • Prevent complications: Poor oral health can lead to complications in people with diabetes. Gum disease can cause blood glucose levels to rise, making it harder to manage diabetes [5]. Additionally, severe gum disease can increase the risk of heart disease and stroke, which are already higher in people with diabetes [6].
  • Improve overall health: Taking care of your oral health can positively impact your overall well-being. A healthy mouth is essential for proper nutrition, as it enables you to chew and digest food effectively. Furthermore, good oral health can boost your self-esteem and quality of life.
  • Detect problems early: Regular dental check-ups allow your dentist to identify and treat oral health issues before they become more severe. Early detection and treatment of problems can save you time, money, and discomfort.

Tips for Maintaining Healthy Teeth and Gums

Here are some tips for maintaining good oral health if you have diabetes:

  • Control your blood glucose levels: Keeping your blood glucose levels in check is crucial for maintaining good oral health. Work with your healthcare team to develop a diabetes management plan that includes monitoring your blood glucose levels, eating a balanced diet, exercising regularly, and taking prescribed medications as directed.
  • Brush and floss regularly: Brush your teeth at least twice a day with a soft-bristled toothbrush and fluoride toothpaste. Floss daily to remove plaque and food particles from between your teeth and along the gumline.
  • Visit your dentist regularly: Schedule dental check-ups and cleanings at least twice a year or as recommended by your dentist. During your appointment, inform your dentist about your diabetes diagnosis and any medications you are taking. This will help your dental care provider tailor your treatment plan accordingly.
  • Quit smoking: Smoking increases the risk of gum disease and other oral health problems. If you smoke, quitting can significantly improve both your oral health and overall well-being.
  • Stay hydrated: Drinking water throughout the day can help combat dry mouth and wash away food particles and bacteria. Avoid sugary drinks, as they can contribute to tooth decay.

Be vigilant for signs of oral health issues: Regularly check your mouth for any signs of gum disease or other problems, such as red or swollen gums, bleeding when brushing or flossing, persistent bad breath, or loose teeth. If you notice any of these signs, contact your dentist as soon as possible.


How often should people with diabetes see their dentist?

People with diabetes should visit their dentist at least twice a year or more frequently if recommended by their dental care provider. Regular dental check-ups are crucial for early detection and treatment of oral health issues.

Can poor oral health affect diabetes management?

Yes, poor oral health can negatively impact diabetes management. Gum disease, for instance, can cause blood glucose levels to rise, making it more difficult to manage diabetes. Maintaining good oral health is essential for preventing complications and ensuring effective diabetes management.

Are there any specific oral health products recommended for people with diabetes?

There are no specific oral health products designed exclusively for people with diabetes. However, using a soft-bristled toothbrush, fluoride toothpaste, and dental floss or an interdental cleaner can help maintain good oral hygiene. If you experience dry mouth, consider using a saliva substitute or sugar-free gum to stimulate saliva production.


Diabetes and oral health are closely connected, making dental care an essential aspect of diabetes management.

By maintaining good oral hygiene, visiting your dentist regularly, and controlling your blood glucose levels, you can reduce the risk of oral health problems and improve your overall well-being.
