Dental alveoli (singular ''alveolus'') are sockets in the
jaws in which the roots of
teeth are held in the
alveolar process
The alveolar process () or alveolar bone is the thickened ridge of bone that contains the tooth sockets on the jaw bones (in humans, the maxilla and the mandible). The structures are covered by gums as part of the oral cavity.

The periodontal ligament, commonly abbreviated as the PDL, is a group of specialized connective tissue fibers that essentially attach a tooth to the alveolar bone within which it sits. It inserts into root cementum one side and onto alveolar ...
. The lay term for dental alveoli is tooth sockets. A
joint that connects the roots of the teeth and the alveolus is called ''
gomphosis'' (plural ''gomphoses''). Alveolar bone is the bone that surrounds the roots of the teeth forming bone sockets.

Etymology
1706, "a hollow," especially "the socket of a tooth," from Latin alveolus "a tray, trough, basin; bed of a small river; small hollow or cavity," diminutive of alvus "belly, stomach, paunch, bowels; hold of a ship," from PIE root *aulo- "hole, cavity" (source also of Greek aulos "flute, tube, pipe;" Serbo-Croatian, Polish, Russian ulica "street," originally "narrow opening;" Old Church Slavonic uliji, Lithuanian aulys "beehive" (hollow trunk), Armenian yli "pregnant"). The word was extended in 19c. anatomy to other small pits, sockets, or cells.
Socket preservation
Socket preservation or alveolar ridge preservation (ARP)
is a procedure to reduce bone loss after
tooth extraction to preserve the dental alveolus (tooth socket) in the
alveolar bone. A
platelet-rich fibrin Platelet-rich fibrin (PRF) or leukocyte- and platelet-rich fibrin (L-PRF) is a second-generation PRP where autologous platelets and leukocytes are present in a complex fibrin matrix to accelerate the healing of soft and hard tissue and is used as a ...
(PRF)
membrane containing bone growth enhancing elements can be stitched over the wound or a graft material or scaffold is placed in the socket of an extracted tooth.
The socket is then directly closed with stitches or covered with a non-resorbable or resorbable membrane and
sutured.
Pathology
The swelling of the dental alveoli can result in
alveolitis, causing pain and discomfort to the mouth.
