The visible portion of the tooth is the crown. The outer surface of the crown is made of enamel. Just beneath the enamel is dentin, a substance harder than bone. The gum surrounds the base of the tooth.
The root of the tooth extends down into the jaw bone and provides circulation and sensation to the tooth. The root contains blood vessels and nerves, which supply circulation and sensation to the entire tooth. The area is known as the "pulp" of the tooth.
The jaw bone contains all the teeth and provides stability and mobility for the mouth and teeth for chewing. The lower jaw bone is called the mandible and the upper jaw bone is called the maxilla.

The hard part of the tooth is actually not a living structure. The living structures are the nerves and blood vessels that are inside the tooth.
What is the structure of a pig tooth?
A pig tooth consists of a crown, roots, dentin, enamel, pulp cavity, and cementum. The crown is the visible part of the tooth, while the roots anchor the tooth in the jaw. Dentin is the hard tissue under the enamel, and the pulp cavity contains nerves and blood vessels. Cementum covers the roots and helps attach the tooth to the jawbone.
Tooth structure includes?
Tooth structure includes enamel, dentin, pulp, and cementum. Enamel is the hard outer layer, dentin makes up most of the tooth, pulp is the innermost part containing nerves and blood vessels, and cementum covers the tooth roots.

What is the difference between developmental anatomy and embryology anatomy?
Developmental anatomy is more emphasis on the process of tooth eruption during the developmental period of the child, whereas embryology anatomy is more emphasis on the process of tooth development during the embryological stages of the fetus. Another way to view it is that developmental anatomy is everything from when the tooth begins to erupt into the oral cavity vs. embryology anatomy is everything from the beginning of tooth bud formation (dental lamina) to complete tooth formation. [Remember even though the crown has erupted into the oral cavity that does not mean the tooth has completed formation, the root is still developing and forming. Therefore developmental anatomy and embryology anatomy overlaps in time period.]

Does a tooth consist of more dentin enamel or cementum?
Mostly dentin, check the drawing in the "Dental Anatomy" link below.
Why is there a Small size pin hole in first molar?
The small pin hole in the first molar is the natural opening of the tooth's root canal, called the apex. This opening allows for nerves and blood vessels to enter the tooth to supply nutrients. It is a normal part of tooth anatomy and does not indicate any problem.
What is Anatomy of teeth?
Anatomy of teeth refers to the basic physical structure, shape, and size of teeth. All teeth have some common characteristics. Other characteristics are unique to specific types of teeth. Common characteristics include enamel covering the clinical crown of the tooth; cementum, covering the clinical root of the tooth; and dentin, which serves to insulate the nerve of the tooth; the pulp, which consists of the nerve and blood supply to the tooth. Periodontal ligament attaches all teeth to the adjacent bone. Unique characteristics of tooth anatomy includes the number and size of roots, the number and size of cusps on the crown; and the overall size and shape of the crown, which is determined by the unique function of each tooth. Some teeth are designed to cut (incisors) and are are therefore chisel-shaped. Other teeth are designed to grind (molars) and therefore have multiple cusps similar to cogs on a gear wheel that interlock with other teeth. Still other teeth are designed to rip, and they are a hybrid between incisors and molars (cupids, bicuspids).

What are the molar width?
Molar width refers to the width of a molar tooth in the mouth. It can vary based on individual anatomy, with the average adult human molar width being around 9-11 mm. Molar width is important for determining tooth alignment and occlusion in the mouth.
How do you carve a tooth out of a wax block?
yes , carving can be done of various materials includingwax.In dental anatomy , the subject of dentistry (undergraduate) ,students carve the tooth on wax to desired shape.Like maxillary central incisor , mandibular molar,can be carved on wax.With the help of measurement's like , length of crown of tooth, length of root of tooth, wax can be easily converted into life size tooth.
