What facial bone contains sockets of upper teeth?
The curved, inferior margin of the maxillary bone that forms the upper jaw and contains the upper teeth is the alveolar process of the maxilla (Figure 6.25). Each tooth is anchored into a deep socket called an alveolus. On the anterior maxilla, just below the orbit, is the infraorbital foramen.
What are teeth sockets?
The socket is the hole in the bone where the tooth has been removed. After a tooth is pulled, a blood clot forms in the socket to protect the bone and nerves underneath. Sometimes that clot can become dislodged or dissolve a couple of days after the extraction.
What structure holds the tooth in its socket?

How many bones make up the upper jaw?
The two maxilla or maxillary bones (maxillae, plural) form the upper jaw (L., mala, jaw). Each maxilla has four processes (frontal, zygomatic, alveolar, and palatine) and helps form the orbit, roof of the mouth, and the lateral walls of the nasal cavity.
Is a tooth socket made of bone?
3 Alveolar Bone. The alveolar bone is that part of the mandibular and maxillary bone which surrounds the teeth and forms the tooth sockets. The bone of the tooth socket is a dense cortical plate into which the principal fibers of the periodontal ligament are inserted, referred to as Sharpey’s fibers.
How common is dry socket in upper teeth?
Dry socket is uncommon after a routine extraction, occurring only about 2% of the time, and it rarely happens in upper teeth. In fact, almost all dry sockets develop after lower molars are removed.
What component of a tooth is present in the crown neck and root?
Dentin is a layer of mineralized tissue just below the enamel. It extends from the crown down through the neck and root.
How are teeth attached?
The teeth are connected with the walls of the tooth sockets and anchored in the jaws by the periodontal ligament and the cementum. The ligament is made up of connective tissue and contains collagen fibers. These fibers are especially strong so that the teeth can withstand the great pressure put on them while we chew.
