: How does a dead tooth not release harmful bacteria after a root canal?

Question

So. I hear a root canal is to save the structure of a tooth for function moreso than anything. But unless they clean out all the nerves/pulp and such, wouldn’t they decay and cause detrimental bacteria to infect the area eventually?

​

And do children need root canals for a number 30 molar? Do they not grow back?

Answer 1

They do clean out all the pulp, then thoroughly disinfect and seal it. And it’s rare but they can get infected.
