1 Sometimes, the larger molars cause more discomfort due to their larger surface area that can't slice through the gum tissue as an erupting incisor is capable of doing.  Most children have a complete set of 20 deciduous teeth (known as baby teeth or milk teeth) by 30 months of age.
Nociceptive, or somatic, pain is the common discomfort we have all experienced as a result of injury -- a paper cut, a broken bone, or appendicitis, among other things. Somatic pain makes sense to us; we can understand the patient's pain.
Nociceptive pain may also be divided into visceral, deep somatic and superficial somatic pain. Visceral structures are highly sensitive to stretch, ischemia and inflammation, but relatively insensitive to other stimuli that normally evoke pain in other structures, such as burning and cutting.he term 'psychogenic' assumes that medical diagnosis is so perfect that all organic causes of pain can be detected; regrettably, we are far from such infallibility... All too often, the diagnosis of neurosis as the cause of pain hides our ignorance of many aspects of pain medicine.
