Gum inflammation is pretty prevalent across the UK. However, 10% of the population seem to suffer from more severe forms of gum disease. Periodontal disease is a primary cause of tooth loss in adults, caused by the bacteria-filled plaque coating the surface of your teeth. Symptoms generally begin with inflamed gums before progressing to bad breath and tooth loss. Periodontal disease attacks the gums, bones and other supporting tissues of the teeth.
