Do you know the impact of diabetes on oral health?

Do you know the relationship between diabetes and oral health? We clarify.

Diabetes is a chronic disease that affects millions of people worldwide, characterized by the body's inability to regulate blood glucose levels. Although its most well-known complications include cardiovascular, kidney, and neurological problems, did you know that diabetes also has a significant impact on oral health? In this article, we will explore how diabetes influences mouth health, what the most common problems are that may arise, and what preventive measures should be adopted.

What exactly does diabetes consist of?

Diabetes is a disease that causes instability in blood glucose concentration (sugar) due to a deficiency of the hormone insulin, which regulates these levels. Diabetics may thus oscillate between states of hyperglycemia - characterized by elevated glucose concentration in the blood - and hypoglycemia - when sugar levels are too low.

Type 1 and Type 2 diabetes are the most common. In Type 1, the immune system destroys the insulin-producing cells in the pancreas, whereas in Type 2, the body's cells become resistant to insulin, making it insufficient to meet needs.

What is the relationship between diabetes and oral health?

Diabetes and oral health are highly related. On one hand, as diabetics have deficiencies in their immune system and changes in blood microcirculation, their response to complications in the oral cavity is diminished, increasing susceptibility to infections. This scenario makes it essential to understand the implications of this relationship.

But what are the most common oral problems in diabetics?

  • Periodontal disease: Periodontal disease is an infection of the gums that can lead to the loss of bone support and eventually teeth. People with diabetes have a significantly higher risk of developing this condition, as elevated glucose levels favor the growth of harmful bacteria in the mouth. At the same time, the limited ability to respond to such complications and vascular changes hinder the control of inflammation, which can even lead diabetics to suffer from premature tooth loss.

  • Oral candidiasis: Oral candidiasis is a fungal infection caused by the proliferation of fungi from the genus Candida. It is more common in individuals with diabetes, as the increased glucose in saliva serves as food for the fungi, facilitating the development of the infection.

  • Xerostomia (dry mouth): Dry mouth is also a common complaint among people with diabetes, due to reduced saliva production. This phenomenon causes not only discomfort but also increases the risk of dental caries and oral infections.

  • Delayed healing processes: Due to compromised immune system and peripheral blood circulation, individuals with diabetes have slower healing processes after dental procedures such as extractions or surgeries. 

Essential care for oral health in people with diabetes

Although diabetics have a higher propensity for oral complications, it is possible to minimize these risks through some care. Some of the essential measures include:

Glycemic control: Keeping blood glucose levels within healthy limits is the first and most important step in preventing oral problems. Effective glycemic control reduces the risk of infections and inflammation in the mouth.

Cautious oral hygiene: A rigorous oral hygiene routine is essential. It should include brushing teeth at least twice a day with fluoride toothpaste, using dental floss daily (and before brushing), and using oral rinses recommended by the dentist or oral hygienist.

Regular visits to the dentist and hygienist:  Regular consultations with the dentist allow for the early detection of oral problems and, if necessary, immediate treatment of any complications. In these consultations, it is essential to inform the dentist about the diabetes diagnosis so that they can adjust care and treatments as needed. The accumulation of dental plaque and tartar in these patients is particularly serious due to the reduced inflammatory response in the gums; therefore, they should have tartar removal and oral hygiene consultations at shorter intervals to avoid gum compromise.

Proper hydration: To avoid dry mouth, it is important to maintain hydration. The use of saliva substitutes or sugar-free lozenges can also be a good solution to help stimulate saliva production.

Dietary changes: A balanced diet not only helps to control diabetes but also directly benefits oral health. Reducing the consumption of high-sugar foods is essential to prevent cavities and other oral conditions.

The importance of oral health education to avoid complications

Being aware of the impact of oral health on diabetes and vice versa is crucial for preventing complications. It is essential, therefore, that patients with diabetes receive guidance from health professionals from various fields, such as dentists and nutritionists, having regular consultations. Additionally, raising patients' awareness of this need through campaigns and prevention programs can be an excellent way to promote healthy habits.

The relationship between diabetes and oral health is complex and requires an integrated approach. Proper management of this disease, through good oral hygiene practices and regular visits to the dentist, can prevent complications and significantly improve patients' quality of life.
