Gum disease (periodontal disease or periodontitis) is a common problem in Australia. Figures from the Australian Institute of Health and Welfare show 15% of people aged 25 to 44 and 35% of the population aged 45 to 64 have moderate or severe periodontitis. This figure increases to more than half the population in those aged over 65. Periodontitis or periodontal disease is a bacterial infection often resulting from poor oral hygiene and which causes inflammation. Without prompt professional dental care,it can destroy gum tissue, ligaments and bone structure supporting the teeth. In severe cases, it can result in tooth loss and may even affect general health.
