Tooth decay is caused by a thin, white, sticky film called plaque. Plaque constantly accumulates on your teeth and contains harmful bacteria. When the plaque is combined with sugars from the foods you eat, it forms an acid. The decay process begins when this acid attacks the tooth enamel. If the decay is not treated early, the cavity will rapidly progress toward the pulp in the central part of the tooth. If the decay continues into the pulp, infection may set in.
X-rays are used to detect hidden areas of tooth decay and possible decay between your teeth. To repair the decayed tooth, your dentist will clean out the decayed area and replace it with a filling material. The proper and most inexpensive approach to tooth decay is its prevention, early detection and treatment. Good home care (proper brushing and flossing) and a healthy diet can help prevent tooth decay.
