Each tooth consist of three main parts; the crown, the neck and root. The crown is the visible part of the tooth; it is the portion that lies above the gum tissue. The neck is the area of the tooth between the crown and the root. The root is the portion of the tooth that extends through the gum and into the bone of the jaw. Each tooth is covered in a hard, outer coating called enamel. Every day, a thin film of bacteria called dental plaque builds up on your teeth. The bacteria in plaque produce acids that can begin to harm enamel. Over time, the acids can cause a hole in the enamel. This hole is called a cavity. Brushing and flossing your teeth can protect you from decay, but once a cavity happens, a dentist has to fix it. Gum disease begins when plaque builds up along and under the gum line. This plaque causes infections that hurt the gum and bone that hold teeth in place. Sometimes gum disease makes gums tender and prone to bleeding. This problem, called gingivitis, can often be fixed by daily brushing and flossing.
There are number of ways you can prevent gum disease: 1. Brush your teeth twice a day with fluoride toothpaste. 2. Floss once a day. 3. Visit your dentist regularly for a checkup and cleaning. 4. Eat a well-balanced diet. 5. Quit smoking - smoking increases your risk for gum disease!
