I used to work with dentists and dental lab technicians, and well, the whole department. I paid them a visit this morning. I described the "supposed" wrong done to me in cracking a tooth, the cost of root canals, etc. I learned some really smart things.
Number one, if the tooth does not hurt, it does not necessarily need a root canal. Number two, capping the tooth is a good idea to keep it from further damage.
Number three, I should get ahold of the original x-rays prior to any work being done as they will give the true nature of any caries or decay.
Number four, if the tooth was decaying, then the crack was inevitable.
It's who you know that can help with the what you know. Knowledge is power. And knowing things has always allowed me to feel better in control of those things that affect me. Especially when it has to do with my smile.
