Which of the following is NOT a potential identifier of nonodontogenic toothache?

The rationale for identifying that option D is not a potential identifier of nonodontogenic toothache lies in the characteristics of the pain described. Quick, sharp, hypersensitive responses that subside quickly are often associated with dental origin tooth pain, such as hypersensitivity due to enamel erosion, gingival recession, or reversible pulpitis. These types of pain tend to have a clear trigger and are typically linked to a dental cause, suggesting that they do not align with nonodontogenic toothaches.

In contrast, the other identifiers involve pain characteristics that are more indicative of nonodontogenic sources. Spontaneous multiple tooth pain can point towards systemic issues or neuropathic pain patterns rather than localized dental problems. Stimulating, burning, non-pulsatile toothaches often reflect conditions like neuralgia or referred pain from other body systems rather than dental pathologies.

Additionally, pain referral from muscle trigger points suggests a myofascial origin, highlighting how referred discomfort can mimic dental pain without any direct involvement of the teeth or gums, which is another hallmark feature of nonodontogenic toothaches.
