Mouth is the window to the body. Gum disease is a common problem, and is often why people lose their teeth. Gum disease also known parodontite-is a bacterial infection that affects 40% of adults worldwide and can lead to tooth loss. Gum disease is very common and affects 3 out of every 4 adults over the age of 35 in the UK. Gum disease, not cavities, is the main cause of tooth loss. Only 60% of women in the UK, aged between 45 can claim to have all their teeth. Gum disease in just something that happens later in life, more than half of children have some form of gum disease. Smoking causes 50% of all cases of gum disease in the United Kingdom. Periodontal disease may affect one or more teeth. It begins when the bacteria in plaque causes the gums to become inflamed. Gums separate from the teeth, forming pockets (spaces between teeth and gums) that become infected. As the disease progresses, the pockets deepen and more gum tissue and bone are destroyed. Often, this destructive process is very mild symptoms. More commonly, gum disease develops when plaque is allowed to build long and under the gum line.
