Answer: The gate-control theory of pain modulation
Explanation: when we touch a hot surface, receive insect bite or a traumatic experience some signals are sent to the brain that causes the individual to withdraw from the causative agent or respond in a way to reduce the pain. The gate-control theory of pain modulation proposed that activation of non nociceptive fibres ( nerves which do not transmit pain signals)can interfere with signals from pain fibers, thereby inhibiting pain.
Therefore by rubbing your skin after receiving a painful stimulus often result in a feeling as though the pain has been lessened is an example of gate-control theory of pain modulation.
Rubbing the skin after receiving a painful stimulus lessened the pain because it is hypothesized that inhibitory interneurons are activated by the collaterals of an activated neuron associated with a mechanoreceptor from the skin.
The gate-control theory of pain modulation may account for this phenomenon.
You don't handle it at work u wait untill you have clocked out of the office and then you pull them to the side and try to have a discussion and if they do not want to have a grown up discussion and then remove yourself from the situation .
I would explain to her that most likely the teeth will not repair themselves due to the fact that, unlike bone, enamel does not contain cells that are capable of remodeling and repair. However, some remineralization is possible.
