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.
Once stimulated, a nociceptor sends a signal along a chain of nerve fibers via the spinal cord to the brain. Nociception triggers a variety of autonomic responses and may also result in a subjective experience of pain in sentient beings.Nociceptive neurons generate trains of action potentials in response to intense stimuli, and the frequency of firing determines the intensity of the pain.he gate control theory of pain, proposed by Patrick David Wall and Ronald Melzack, postulates that nociception (pain) is gated by non-nociception stimuli such as vibration. Thus, rubbing a bumped knee seems to relieve pain by preventing its transmission to the brain.
