Root canal is when the pulp is in tooth and the endodontics has to go in and clean out the tooth completely and put meds in. the tooth is pretty much dead though after the treatment is done
yes its very expensive
when they do the root canal is it worse than getting a deep cavity done. how long does it take?
i had 4 cavities fixed last year and my teeth are in good condition now but he said i will need a couple root canals in the future
