Root canal treatment is necessary because the teeth do not heal on their own. Without treatment, the infection spreads, bones around the teeth begin to degenerate, and the teeth may fall off. Until one is forced to seek urgent dental attention, the pain usually worsens. The only option is to remove the teeth, which may cause the surrounding teeth to bend and cause bites. Although extraction is cheaper, the space left will require implants or bridges, which may be more expensive than root canal treatments. If you have a choice, it is best to always keep the original teeth.
