Gum disease arises as a result of bacterial infection of the gums, especially at the tooth margins. It is often assumed that excessive accumulation of plaque, arising from inappropriate dietary habits, is a factor in this condition, but there is little evidence for any material influence of diet. The milder forms of gum disease are extremely common in all populations. More severe disease is the most frequent cause of tooth loss in older people. The best form of protection from gum disease is regular tooth brushing.
