The only other alternative is extraction of the tooth. The extracted tooth must then be replaced with an implant, bridge or removable partial denture to restore chewing function and to prevent adjacent teeth from shifting. Because these options require extensive surgery or dental procedures on adjacent healthy teeth, they can be far more costly and time consuming than retreatment and restoration of the natural tooth. No matter how effective tooth replacements are, nothing is as good as your own natural tooth. You’ve already made an investment in saving your tooth. The payoff for choosing retreatment could be a healthy, functioning natural tooth for many years to come.
