Plaque

Plaque is a soft, sticky film that builds up on your teeth and contains millions of bacteria. The bacteria in plaque cause tooth decay and gum disease if they are not removed regularly through brushing and flossing.

Causes

Plaque develops when foods containing carbohydrates (sugars and starches), such as milk, soft drinks, raisins, cakes, or candy are frequently left on the teeth. Bacteria that live in the mouth thrive on these foods, producing acids as a result. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay. Plaque can also develop on the tooth roots under the gum and cause breakdown of the bone supporting the tooth.

Prevention

To prevent plaque buildup, brush your teeth at least twice a day with a soft, rounded-tip bristled toothbrush. Pay particular attention to the space where the gums and teeth meet. Use a fluoride-containing toothpaste. Floss between teeth at least once a day to remove food particles and bacteria. See your dentist or oral hygienist regularly for cleanings, usually every six months. Antimicrobial mouth rinses and toothpastes reduce the bacterial count and inhibit bacterial activity in dental plaque, which can cause gingivitis, an early, reversible form of periodontal (gum) disease.

Treatment

Dental cleanings and check-ups allow your dentist to identify any early signs of plaque. Regular cleanings and good oral health habits can prevent plaque from causing tooth decay or gum disease.
