I had new crowns put on my two front teeth. One had already had a root canal, many years ago. The other was a healthy tooth which the dentist recommended getting a crown for -- to get a "better match". The first crown put on this tooth had a crack on the face that could definitely be felt by the tongue. The dentist removed the crown and replaced it. For this second attempt, he filed the original tooth down even further. While wearing the second temp, I experienced extreme sensitivity to cold. Once the final crown was installed, I began to have persistent throbbing pain, sensitivity to cold, heat, and pressure. The dentist has advised me that the pain will subside, but it has now been over a week and the pain has only gotten worse. I went to get a second opinion, and the second dentist prescribed painkillers but basically told me to wait it out. What I don't understand is, if this is expected pain after crown work, why didn't I have this problem after the first crown attempt? Was the tooth filed too close to the nerve? I am frustrated with the diagnosis that I need to be a tough guy regarding the pain -- particularly when the pain is so intense that it wakes me up at night, has me doubling over in pain with a glass of cold milk, and is so sensitive that I don't dare eat anything sturdier than baby food. It was a perfectly healthy tooth before this work started, and now I have been in agony for weeks. Can I be helped or is it time to consider euthanasia?
