Ex.17. Speak on the types of periodontal diseases.Ex.18. Make up a dialogue on types of periodontal diseases. Overview Periodontal (gum) diseases are infections of the gums and bone that surround and support the teeth. The direct cause of periodontal diseases is plaque - the soft, sticky, colorless film of bacteria that forms constantly on the teeth and gums. The following are warning signs of periodontal disease: bad breath, red or swollen gums, tender or bleeding gums, painful chewing, loose teeth, sensitive teeth. Periodontal diseases are often classified according to their severity. They range from mild gingivitis, to more severe periodontitis, and more uncommon but serious acute necrotizing ulcerative gingivitis, which can be life-threatening. The goals of gum disease treatment are to promote reattachment of healthy gums to teeth; reduce swelling, the depth of pockets, and the risk of infection; and to stop disease progression. Good oral hygiene prevents periodontal disease. Brush the teeth at least twice every day, get a new toothbrush every 3 months, use a toothpaste that contains fluoride. Eat a well-balanced diet.
