Parts of a Tooth Do you remember losing your teeth when you were younger, only to have new permanent come in? Have you lost all of your yet? The periodontium is made up of the gums, ligaments and jawbones. This supports the teeth and hold them in place. A tooth is made up of 3 main parts: crown, neck and root. The crown is visible portion of the tooth; covered with enamel. Beneath the enamel is dentin, a layer of connective tissue that contributes to the shape and hardness of a tooth which acts as a barrier to protect the pulp. The pulp extends into the root canal and provides nourishment to the tooth. Do you remember losing your teeth when you were younger, only to have new permanent come in? Have you lost all of your yet?

Healthy Teeth and Mouth Regular oral hygiene is necessary for healthy, clean teeth. One of the mian threats to the health of your teeth is the bacteria that inhabit your mouth and live on the sugar found in foods you eat. Plaque can coat your teeth, and as it does this, it prevents your saliva, which has the substances to protect teeth from bacteria, from reaching the tooth surface. In areas where plaque builds, bacteria thrives and the acids from the bacteria breaks down enamel. If this continues, a hole, or cavity, is formed in the tooth. If continued without proper treatment, you may have to get it pulled! PRACTICE GOOD ORAL HYGIENE! Brushing teeth after eating removes plaque from surface of the teeth, before bacteria can produce any acid to harm it! FLOSS TOO! Regular oral hygiene is necessary for healthy, clean teeth.
