Plaque is a film of
bacteria that forms on your teeth and gums after eating foods that produce
acids. These foods may include carbohydrates
(starches and sugars), such as candy and cookies, and starchy foods such as
bread, crackers, and cereal.
Tooth decay, commonly known as cavities, occurs when plaque
remains on your teeth for an extended period of time, allowing the bacteria to
‘eat away’ at the surfaces of your teeth and gums. Ironically, the areas
surrounding restored portions of teeth (where fillings, or amalgams have been
placed) are particularly vulnerable to decay and are a breeding ground for
bacteria.
Plaque can lead to gum irritation, soreness, and redness.
Sometimes, your gums may begin to bleed as a result of plaque. This gradual
degeneration can often cause gums to pull away from teeth. This condition is
called receding gums.
Long-term plaque can lead to serious problems. Sometimes, the
bacteria can form pockets of disease around tooth structures, eventually
destroying the bone beneath the tooth.
