|The most number of first impressions are formed by the brightness of your smile, therefore by the whiteness and straightness of your teeth. Such appearance of your teeth is essential, but what is inside your teeth is even more essential to both your overall health and the pleasant appearance of your smile.|
Our teeth are consists of a complex set of layers. From the outside, each tooth looks like a solid white object, but in reality teeth are complex living tissues made up of several layers as the following:
Enamel is the white, outmost layer of the tooth that overlays the crown (the part of your tooth that you see, above the gumline). Besides, enamel is the hardest matter in your body. It supplies strength for biting and chewing, and it protects the inner layers from plaque and bacteria that cause decay.
Dentin is the second, yellowish layer inside your tooth. This hard substance contains millions of tubules. Dentin is softer than enamel and presents support for it, acting like a shock absorber to take the impact of biting and chewing. When a cavity develops, it destroys the enamel and attacks the dentin.
As for the pulp – this is the innermost layer of the teeth. It includes the nerves and blood supply for a tooth. This soft tissue extends from the pulp chamber at the top of the tooth, down through the root canals in the tooth roots. If decay gets the pulp or root canals, a filling may not be enough to guard the strength and health of your tooth.
The roots of your teeth (the parts of your teeth that are below the gumline) also have blood vessels and nerves that join your teeth to the nerves and blood vessels of your jawbone. The roots are covered with cementum. This very thin layer of tissue "cements" your teeth to the bone.
Disease and decay that reach the roots are tremendously serious and painful. That's why it's significant for us to examine both the outsides and the insides of your teeth.
