Who has heard of periodontal disease? Let’s ask the experts and see what they say. Periodontal disease is a chronic disease that affects the tooth- supporting structure (bone, periodontal ligament and gums). Periodontal disease has two parts Gingivitis (Inflammation or infection of the gums) and Periodontitis (where there is already destruction of the supporting bone around the teeth). Periodontitis or pyorrhea is an inflammatory disease which affects the tooth-supporting structures. Periodontitis involves the progression of the bacterial infection to the deeper tooth-supporting tissues resulting in the gradual destruction of the bone around the teeth. They are usually induced by dental plaque accumulation around the teeth. Dental plaque is a combination of bacteria food debris and calculus, which cover the teeth when there is lack or poor oral hygiene. At first it is not visible, but when brushing and flossing techniques are not carried out effectively, plaque accumulates, turning into a white-yellow deposit. The plaque accumulation results in an inflammation of your gums, known as gingivitis. The gums turn into a dark red colour and bleed easily. Gingivitis is reversible and we can completely cure it if the risk factors and etiologic factors are eliminated Periodontal disease is irreversible and cannot be cured. However, it is possible to treat it. If patients address the periodontal disease on time, the dentists may be able to save some or all the teeth. It goes to show oral hygiene is so important to the health of our teeth and gums. I don’t feel that there is enough information about this disease in general dentistry and some patients do not even know they have this disease until they have come to see us.
