Plaque
Plaque is a yellow sticky film that forms on the teeth and gums. The bacteria in plaque release acid that attacks tooth enamel. Tooth decay can occur after repeated attacks. Some food causes plaque bacteria that produce acids. Thorough daily brushing and flossing can prevent tartar from forming on the teeth.
Plaque can also cause irritation to the gums, making them red, tender, or bleeding easily. In some cases, the gums pull away from the teeth, leaving cavities inhabited by bacteria and pus. If this is not treated, bones around the teeth can be destroyed. Teeth may become loose or have to be removed as with periodontal (gum) disease in mostly adults. Eating a balanced diet and limiting snacks can prevent tooth decay and periodontal disease. Nutritious foods such as raw vegetables, plain yogurt, cheese, or a piece of fruit are considered good snack foods to grab.[6]
[edit] Flossing
The use of dental floss is an important element of oral hygiene, since it removes the plaque and the decaying food remaining stuck between the teeth. This food decay and plaque cause irritation to the gums, allowing the gum tissue to bleed more easily. Acid forming foods left on teeth also demineralise teeth eventually causing cavities. Flossing for a proper inter-dental cleaning is recommended at least once per day, preferably before bedtime, to help prevent receding gums, gum disease, and cavities between the teeth.
It is recommended to use enough floss to enable easy use, usually ten or more inches with three to four inches of taut floss to put between teeth. Floss is then wrapped around the middle finger and/or index finger, and supported with the thumb on each hand. It is then held tightly to make taut, and then gently moved up and down between each tooth. It is important to floss under visible areas by curving the floss around each tooth instead of moving up and down on gums, which are much more sensitive than teeth. However, bleeding gums are normal upon first usage of floss, and will harden with use.[7] One should use an unused section of the floss when moving around different teeth. Removing floss from between teeth requires using the same back-and-forth motion as flossing, but gently bringing the floss up and out of gaps between teeth
