Referred pain

Hello!

My crowned first molar is sensitive to anything hot but not to cold. My second molar, which has also a crown, is sensitive to cold but not to hot. This tooth is also aching. Both teeth are on the top left side of my mouth. The dentist thinks it’s a referred pain but she is not really sure what is the causing it. She said it may be caused by a crack or infection. She wants me to observe both teeth more if the sensitivity of each gets more intense. Any thoughts about this? I am taking Vicodin and antibiotics as a precaution for the infection. Thanks!

It's always difficult to make a diagnosis over the internet, but generally if a tooth hurts with heat, and the pain lingers (ie. lasts for more than 10 seconds), then it's almost certain that the tooth nerve is dying. This means that the tooth will need a root canal, or else extraction. Your dentist will be aware of this, but she may be concerned about exactly which tooth is the heat sensitive one. It may NOT be the one that you think. This is what she means by referred pain. It could be a completely different tooth. She wants to make sure she is going to treat the correct tooth.

In between every vertebrae in the spine is a cushion of jelly which acts as a shock absorber and cushions each and every step. When the disc bulges backwards it traps the nerve where it leaves the spinal canal. This causes pressure which results in pain but where the pain is felt depends on how much pressure the disc is exerting on the nerve. The body works like a telephone exchange. If there is a problem on the line you can only tell which phone line is out of order not where the fault actually lies. The body is very similar. If there is a problem between the brain and say the ankle the brain can not tell exactly where along the nerve the fault lies.
