Tooth decay is a preventable disease caused by acids, formed by large amounts of starches and sugars that eat away tooth enamel. Consuming foods that are rich in sugar and carbohydrates including candy, soft drinks, and fruit juices, leave deposits on your teeth. These deposits interact with bacteria and create a substance known as plaque. Over time the buildup of plaque forms the acids that damage the mineral structure of your teeth.
To prevent further damage has occurring, it may be necessary to fill the tooth with a variety of fillings, enabling the tooth to return to a healthy state. Circumstances may arise however, when damage is so severe that a crown must be placed to make the tooth much stronger and protect it from further damage.
