By studying the anatomy of a tooth and learning about the functions of the many structures, we can better understand the basics of maintaining good oral health and why it is so important to avoid cavities. Let’s take a look at... The crown is the part of the tooth you see when you look in your mouth. The crowns of your back teeth have pointed cusps and depressions.

Usually, teeth have a layer of super-hard enamel covering the entire visible portion of the tooth (known as the crown). Sensitivity occurs when the inner layer (called dentin) is exposed. This dentin is much more porous and [...]
Learn Your Tooth Anatomy, Shape, and Function Teeth differ in shape depending on their function & position in the mouth. On the inside, however, they all share the same basic anatomy. Parts of a Tooth Crown: the visible, chewing portion of the tooth. Root: the portion of the tooth hidden by the gums, it anchors the tooth into the jawbone. (The root makes up about two-thirds of the total length of the tooth.) Enamel: the hard outer covering of the crown of the tooth, [...]
Being mammals, we sport two sets of teeth, the primaries and the permanent. Assuming Mom has already lent strength to her baby's teeth during pregnancy—beginning from week seven of prenatal life—teeth grow through two stages. In the first permutation, teeth take shape; in the second, the cells are actually transformed to perform different functions. All this is percolating as you enjoy pickles and ice cream. When your baby is born, you won't see teeth, but they're there. Enamel and dentin are still forming in [...]
