2 CAUSES AND RELIEF OF DENTAL PAIN.
pulp occurring in this condition Leads to swelling thai
causes a darting, shooting, or throbbing pain in the
tooth, owing to the resistance offered by the unyielding
wall of the pulp cavity to the expansion of the pulp
tissue.
Heat or a lowered position of the head intensifies the
throbbing, since either ivill still further increase the
congestion.
As the dental periosteum is not involved, pain is not
usually felt on the tooth being pressed or bitten into its
socket.
Inflammation of the dental periosteum.—This membrane,
on becoming inflamed, is thickened, and therefore raises
the tooth in its socket ; hence it appears lengthened and
is bitten upon before its neighbours when the jaws are
closed, pain being produced from the periosteum being
squeezed between the two unyielding surfaces of tooth
and socket.
The pain is of a dull, heavy, not throbbing character,
not worse at night, and often relieved by heat and gene-
rally in early stages by pressure.
The tooth is tender to the slightest touch, and the gum
surrounding it is swollen and feels velvety to the finger.
Irritation of the dental pulp.—If the irritation be long
continued and slight, an increased formation of dentine
may take place from stimulation of the odontoblasts.
Irritation of the dental pulp may arise from
(1) Caries with or without the presence of cavities.
(2) Heat and cold ; contact of sweet, sour, or acid
substances.
(3) Conduction of heat and cold through a metal filling.
(4) Exposure of dentine from any cause producing
loss of the enamel, such as friction from bands or dental
plates, wearing down of teeth from excessive use.
