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 is caused by an injury that stimulates pain receptors which recognize and react to a stimulus (pressure, extreme temperatures, irritating substances released by other cells) and send pain signals through the nervous system for recognition and response to an injury or the possibility for injury.ociceptive pain is caused by an injury that stimulates pain receptors which recognize and react to a stimulus (pressure, extreme temperatures, irritating substances released by other cells) and send pain signals through the nervous system for recognition and response to an injury or the possibility for injury.
