Tooth decay happens when plaque or bacteria come in contact with the tooth and is allowed to sit. The bacteria, once fed with sugars, will begin eroding the enamel.
Causes for tooth decay include:
- Poor oral hygiene (brushing / flossing)
- Poor diet
Adults tend to get cavities around old fillings, which may be cracked, rough around the edges or loose in the tooth. Another common form of tooth decay in adults is root cavities. These are likely to occur in adults who have receding gums due to age or periodontal disease. As the gum line recedes, the tooth root becomes exposed. Since root tissue is softer than enamel, it decays more easily.
Floss is cheap, so don't be stingy! Tear off about a forearm's length to start. Wrap one end around the middle finger of one hand to 'anchor' it and pick up the other end about 4-6 inches away with the middle finger of the other hand. This allows you to manipulate the floss with your thumb and fore finger. As you soil a section of floss, 'reel' in another 4-6 inches of clean floss with the anchor finger as you release the floss with the other finger. Never shoe-shine the teeth in a back-and-forth motion as you will either notch your teeth and/or cut your gums.
For most people, a complete radiographic survey should be done every 3 years, and a 'check up' or 'recall' set every 6 to 12 months. A complete set of x-rays is estimated to expose you to the same amount of radiation you get on a flight from San Francisco to Seattle. Doctors use x-rays as an aid in diagnosing problems. Without x-rays 'seeing' the problem will be difficult if not impossible.
