What is a Root Canal and why do I need it?
The term âRoot Canalâ scares people because there is so much misinformation and mythology perpetuated over time. So, letâs set your mind at ease here with an honest description of the feared âRoot Canalâ.
The tooth is the hardest bone in the body. Decay enters through the grooves on the top of the tooth or from areas like in between the teeth where it is easier for bacteria to take shelter. The outer shell of the tooth, called Enamel, is very mineralized and hard but the inner 4 mm of âDentinâ is softer and then you have the âPulpâ or nerve. Once decay passes the hard exterior shell, it will rapidly advance inside the softer âDentinâ and eventually into the âPulpâ. This is a point of no return where the only solution is to remove the infected nerve. This is what is called a Root Canal. Sometimes an antibiotic is needed to help fight this infection while the tooth is being treated.
Letâs go through the steps of a âRoot Canalâ to help you realize that all the exaggerated accounts of this very helpful and safe procedure are completely false.
Imagine that every bone in the body has nerves and blood supply. That is exactly what a tooth is; a hollow, hard shell of bone with nerve and blood supply (remember our friend the âPulpâ?) on the inside.
We need to clean out the infected âPulpâ that lies inside the shell of bone and so we prepare a little hole just as if we were doing a filling except we go a bit further. Now we can actually physically remove all the infection inside the tooth and clean it out with disinfectants. Once it is sterile, we proceed with filling the now hollow interior, with a special plastic material and a paste.
You now have a tooth that is technically âdeadâ but what people forget, is that this dead tooth is surrounded with a very much âliveâ ligament. So the satisfaction of chewing and enjoying food is still there. Yes, the tooth has no nerve once a âRoot Canalâ is done, but it has a surrounding ligament that feeds information back to the brain about pressure while chewing. What a brilliant system, wouldnât you say?
