The pain pathway is mostly transmitted via myelinated Aδ (sharp or stabbing pain) and unmyelinated C nerve fibers (slow, dull, aching, or burning pain) of the trigeminal nerve, which supplies sensation to the teeth and gums via many divisions and branches.

However, since the tooth is typically alive, there is no difficulty dental pain pathway accessing the source of infection and, therefore, antibiotics are more routinely used in conjunction with scaling and root planing.

Acute necrotizing ulcerative gingivitis[ edit ] Mild presentation of ANUG on the gums of the lower front teeth Common marginal gingivitis in response to subgingival plaque is usually a painless condition. It is associated with severe periodontal pain, dental pain pathway gums, "punched out" ulceration, loss of the interdental papillaeand possibly also halitosis bad breath and a bad taste.

Predisposing factors include poor oral hygienesmoking, malnutrition, psychological stress, and immunosuppression.

Antibiotics are not indicated in ANUG management unless there is underlying systemic disease. There is minimal inflammation and recurrent swelling. A radiograph of the above tooth showing chronic pericoronitis, operculum blue arrow and bone destruction red arrow from chronic inflammation.

Dental pain pathway is slightly disto-angular.

Toothache - Wikipedia

Pericoronitis is inflammation of the soft tissues surrounding the crown of a partially dental pain pathway tooth. This leaves the tooth partially erupted into the mouth, and there frequently is a flap of gum an operculumoverlying the tooth.

Bacteria and food debris accumulate beneath the operculum, which is an area that is difficult to keep clean because it is hidden and far back in the mouth. The opposing upper wisdom tooth also tends to have sharp cusps and over-erupt because it has no opposing tooth to bite dental pain pathway, and instead traumatizes the dental pain pathway further.

Periodontitis and dental caries may develop on either the third or second molars, and chronic inflammation develops in the soft tissues. Chronic pericoronitis may not cause any pain, but an acute pericoronitis episode is often associated with pericoronal abscess formation.

Typical signs and symptoms of a pericoronal abscess include severe, throbbing pain, which may radiate to adjacent areas in the head and neck, [20] [25]: Treatment for acute conditions includes cleaning the area under the operculum with an antiseptic solution, painkillers, and antibiotics if indicated.

After the acute episode has been controlled, the definitive treatment is usually by tooth extraction or, less commonly, the soft tissue is removed operculectomy.

If the tooth is kept, good oral hygiene is required to keep the area free of debris to prevent recurrence of the infection. Occlusal trauma may occur with bruxismthe parafunctional abnormal clenching and grinding of teeth during sleep or while awake.

Over time, there may be attrition tooth wearwhich may also cause dentin hypersensitivity, and possibly formation of a periodontal abscess, as the occlusal trauma causes adaptive changes in the alveolar bone.

Height differences measuring less than a millimeter can cause pain. Dentists, therefore, routinely check that any new restoration is in harmony with the bite and forces are distributed correctly over many teeth using articulating paper.

If the high spot is quickly eliminated, the pain disappears and dental pain pathway is no permanent harm. The pain is localized to the socket, and may radiate.

It normally starts two to four days after the extraction, and may last 10—40 days. Cracked tooth syndrome refers to a highly variable [29] set of pain-sensitivity symptoms that may accompany a tooth fracture, usually sporadic, sharp pain that occurs during biting or with release of biting pressure, [30] or dental pain pathway by releasing pressure on the tooth.


Accordingly, there is no single test or combination of symptoms that accurately diagnose a fracture or crack, although when pain can be stimulated by causing separation of the cusps of the tooth, it's highly suggestive of the disorder.

Because of the high variation in treatment and prognosis, dentists often use trauma guides to help determine prognosis and direct treatment decisions.

Those cracks that are irritating the pulp but do not extend through dental pain pathway pulp dental pain pathway can be amenable to stabilizing dental restorations such as a crown or composite resin.

The properties of the sense organs responding to a noxious oral-facial stimulus are first considered. This section is followed by a review of the sensory pathways and mechanisms by which the sensory information is relayed in nociceptive neurones in the brainstem and then transmitted to local reflex centers and to higher brain centers involved in the various aspects of the pain experience--namely, the sensory-discriminative, affective emotionalcognitive, and motivational dimensions of pain.

Reflex and behavioral responses to noxious oral-facial dental pain pathway are dental pain pathway considered. The next section provides an extensive review of how these responses and the activity of the nociceptive neurones are modulated by higher brain center influences and by stimulation of, or alterations e.

The neurochemical processes, involved in these modulatory mechanisms are also considered, with special emphasis on the role of neuropeptides and other neurochemicals recently shown to be involved in pain transmission and its dental pain pathway.
