When infection or decay affects the pulp, root canal therapy can play a vital role to save the tooth. Your dentist will remove the affected pulp along with nerves and bacteria before sealing the area with a special medicated dental sealant. Over time, your tooth will recover as the decay will stop.
A root canal therapy can save a tooth from being extracted. Although some people believe that extracting a tooth is the solution, it can lead to further problems. These include improper jaw shape and problem for the adjacent teeth. Moreover, extracting a tooth cost more compared to getting a root canal therapy at an early stage.
Root canal treatment has long-lasting results with excellent success rate. It usually lasts a life-time unless new infections make their way to the root again.
