Thus, pain is poorly localized, and the level of pain stemming from pulpitis varies based on severity, quality, duration, onset, trigger. As caries invades dentin, the number of permeable dentinal tubules correlates with the degree of pain. Intrapulp pressure have an effect on the sensory nerves of varying diameters: blocking larger diameter ...
Based on the most common causes of toothache (dentin hypersensitivity, periodontitis, and pulpitis), the key indicators become localization of the pain (whether the pain is perceived as originating in a specific tooth), thermal sensitivity, pain on biting, spontaneity of the pain, and factors that make the pain worse.
In response to this movement, mechanoreceptors on the pulp nerves trigger the acute, temporary pain of dentine hypersensitivity. [ 2 ] The fluid flow mechanism behind hydrodynamic theory was first introduced by Alfred Gysi in 1900, and subsequently developed by Martin Brännström in the 1960s through a series of experimental studies .

Your tooth's enamel, cementum, and dentin usually protect the pulp, but if any of those layers are damaged or irritated, the pulp can get inflamed. Cue the pain.
A degree of dentin sensitivity is normal, but pain is not usually experienced in everyday activities like drinking a cooled drink. Therefore, although the terms dentin sensitivity and sensitive dentin are used interchangeably to refer to dental hypersensitivity, [3] the latter term is the more accurate.
“If you have exposed dentin, very thin enamel, exposed cavities or root surfaces showing, the acid in whitening strips can erode more tooth structure than can be remineralized and so should be ...
Pulpit. Pulpitis is an inflammation of the pulp, or the core of the tooth, where the blood vessels and nerves are located. [12] [13] One of the main signs of its appearance is sharp pain that intensifies with high or low temperature. In most cases, pulpitis occurs as a result of neglected caries, and if untreated, it turns into periodontitis.
The pulp is the neurovascular bundle central to each tooth, permanent or primary.It is composed of a central pulp chamber, pulp horns, and radicular canals. The large mass of the pulp is contained within the pulp chamber, which is contained in and mimics the overall shape of the crown of the tooth. [2]
