Re: Are root canals really that bad?
They will numb you before doing any work and if the numbing is done correctly, you won't feel pain. Root canals take longer than filling cavities and you may have to go back a second time for a final cleaning of the root canals. If you have pain, it will be afterwards as the nerves around the tooth will be sore from the work.
But the relief from the tooth pain and knowing you are almost done and getting a nice, new crown should keep you fine. They will give you some pain killers after the procedure in case you need them.
I've had three and don't feel they are too much more than cavities.
