Periodontal disease is the inflammation of the tissues surrounding the tooth. The periodontitis bacteria causes an inflammatory response in the body. The jawbone is affected, causing tooth loss in advanced periodontitis. The dentist not only looks at the health of teeth and molars, but also at the gums. Many people suffer from bleeding gums when brushing. This may mean that the gums are inflamed. The cause of gingivitis is the deposits that settle above and below the gums. This deposit consists of food remains, certain saliva parts and especially bacteria. The acidic secretions of these bacteria cause caries and gingivitis. If this deposit is not removed in time, it will grow in depth towards the tooth root. Space is created between the tooth root and gums, the so-called ‘pocket’. This pocket is the ideal living space for the bacteria.
