Diabetes patients they may suffer from oral problems that alter their dental health. In particular, the high blood sugar levels that characterize this pathology cause damage to the entire body, including the oral cavity.

This chronic disease impairs the body’s ability to metabolize sugar. The excess of this substance in the blood causes damage to multiple organs of the body. Heart, kidney, vision and nervous system problems are some of the most frequent consequences of this disease.

Likewise, there is an alteration of the wound healing and healing processes and an increased risk of suffering infections. The mouth is no stranger to these tissue damage caused by excess sugar in the blood. Do you want to know more about it?

What is the relationship between diabetes and dental health?

The relationship between diabetes and damage to dental health is two-way. In both conditions the inflammatory processes are increased, which causes microvascular alterations in the tissues. Thus, the presence of one of the two conditions predisposes the development of the other or worsens the condition if it already exists.

People with certain oral problems, such as gingivitis and periodontal disease, are more likely to have diabetes than those with healthy gums. Secondly, those with systemic disease often have severe pyorrhea, which in turn make it difficult to control blood glucose.

Thus, having high blood glucose levels increases the chances of developing periodontal disease and, in the long term, teeth can be lost.

Another reason for oral damage is because uncontrolled diabetes blocks the action of white blood cells. These cells are the body’s main defense against infections that can take place in the mouth.

The situation worsens with high levels of glucose in saliva, since it favors the proliferation of bacteria in the mouth and, therefore, damages the health of the teeth and gums.

Having high blood sugar levels raises your risk for diseases like gingivitis, tooth decay, and periodontitis.

What dental health problems does diabetes cause?

Here are the dental health problems that occur most frequently in patients with diabetes.

  • Gingivitis: it is the inflammation of the gum tissue, which increases in size, turns intense red, bleeds and hurts. Weak white blood cells and vascular problems make it difficult for the gums to defend themselves against bacteria in the mouth, making it a frequent and severe problem.
  • Periodontitis: is the evolution of gingivitis. It affects the supporting tissues of the teeth. Deep inflammation and infection damage the periodontal ligament and alveolar bone. In this way, the support of the teeth is affected, which can move and even fall.
  • Dry mouth: If diabetes is not controlled, it can decrease salivary flow, leading to dry mouth. Xerostomia not only causes discomfort to the patient, but also increases the risk of pain, ulcers, cavities, bad breath and infections.
  • Difficulty healing oral tissues: In patients with uncontrolled diabetes, wounds in the mouth caused by trauma or surgery heal with difficulty. Postoperative complications are quite common.
  • Oral candidiasis: it is an infection by a fungus that takes advantage of high sugar levels and a low immune response to proliferate. It usually manifests with ulcers or painful, whitish or red plaques on the oral mucosa. It is more common in patients who wear dentures or who take antibiotics frequently.
  • Cavities: bacteria in the mouth take advantage of carbohydrates in the diet and metabolize them; This generates an acid that demineralizes the hard tissues of the teeth.

Dental care in diabetic patients

People with diabetes are more likely to suffer from conditions that damage their dental health. For this reason, strictly follow certain healthy habits is essential to take care of the mouth. Here are some recommendations.

1. Control blood sugar levels

Most of the complications and tissue damage are caused by high blood sugar levels. For this reason, one of the best ways to avoid damage to dental health and the entire body is to try to keep blood glucose levels close to normal.

In certain cases it may be necessary to take antibiotics before a dental procedure, change meal times or the dose of medication. In that case, the management of the situation between both professionals is the ideal.

If blood sugar levels are not well controlled, only dental emergencies, such as acute infections, abscesses, or trauma, should be treated. Other treatments are postponed until blood glucose levels return to normal.

The dentist must be aware of the existence of diabetes. In addition, you must know the medications that are consumed for their control.
