The tongue, the gums and the teeth are covered by a thick carpet of bacteria composed of an individually varying mixture of different bacteria. Although many of the bacteria are largely harmless, disease-causing bacteria can also become established. The number of bacteria depends largely on a person's oral hygiene. Poor oral hygiene leads not only to an increase in the number of bacteria but also to greater multiplication of the aggressive and harmful species. In young years the consequences are dental caries, in adults very often permanent inflammation of the periodontium (the tissues supporting the teeth) - chronic periodontitis.
Periodontitis a widespread disease
Periodontitis - like high blood pressure - is very often a chronic process extending over many years. It is one of the most widespread diseases in the adult population.
In the early stages of the disease the bacteria are found at the border between teeth and gums (Fig. 1). However, in the course of time the scarcely perceptible inflammatory process leads to the development of pockets between the teeth and the gums. These are the result of destruction of the periodontal tissues. When the erosion of the bone exceeds a critical limit the teeth become loose in their sockets and fall out.
If the bacteria get into the blood
In the pockets the harmful bacteria in particular can multiply unhindered. The human body responds to this situation with inflammation of the gums - in advanced cases the gums also bleed on toothbrushing. The chronic inflammation leads to an increase in the blood vessels in the gums and to an increased flow of blood. Now the bacteria have the opportunity to enter the bloodstream and thus to travel to all parts of the body. While healthy individuals have no bacteria in their blood, patients with chronic periodontitis are constantly at risk. The quantities of bacteria are rarely large enough for the body to respond with fever; however recent scientific findings show that the constant migration of bacteria into the bloodstream over many years is particularly dangerous.
The bacteria lead to changes in the lining of the blood vessels and thus to the increased occurrence of vascular diseases such as heart attacks. The life expectancy of a periodontitis patient decreases with increasing severity of the disease. Patients with susceptible vascular linings, e.g. heart valve patients, should be particularly aware of these risks.
How can periodontitis be treated or prevented?
The sooner periodontitis is treated, the greater are the chances of success. Only the early forms can be completely cured; as the disease progresses it is often only possible to slow down but not completely stop the destructive process.
Because of this difficult treatment situation it is important to begin preventive measures as early as possible. Children with still healthy gums should learn how they can lastingly reduce the number of harmful bacteria by good oral hygiene.
This includes not only regular toothbrushing but also especially the correct technique and individually varying additional aids (dental floss, dental sticks, interdental brushes, chewing gum etc.). The technique must be learned and perfected in special prophylaxis (prevention) sessions. The belief that frequent toothbrushing is equal to good oral hygiene is unfortunately not correct.
