What is a Root Canal?

During root canals, or endodontic treatment, the inflamed or infected nerve is removed and the inside of the tooth is carefully cleaned and disinfected. That area is then filled and sealed with a rubber-like material. 
Please remember, root canal treatments take care of the infection in your tooth but do not restore its functions. At that appointment, a semi temporary filling is placed to cover the opening. Afterwards, the tooth is restored with a crown or filling for protection. 
 
Why do I have to have a Root Canal?[2] ​

Root canals, or endodontic treatment, is necessary when the nerve becomes inflamed or infected. The inflammation or infection can have a variety of causes: deep decay, trauma to the tooth, repeated dental procedures on the tooth, or a crack or chip in the tooth. 
 

How long does it take to get a Root Canal? 

A single root canal appointment will usually last somewhere between 30 to 60 minutes and, in some cases, possibly as long as 90 minutes. ​On rare occasions with severe infections, root canals can take multiple appointments. 

 
Should I chew on my tooth after a root canal? 

After a root canal is finished, it becomes fragile and dry due to the lack of nerve and nutritional supply. 
It is not recommended to chew on the tooth until the final restoration is placed. 
 

How do I restore my tooth after a Root Canal? 

Root canal teeth are susceptible to fracture; therefore, special restoration is required to keep the tooth strong. In most cases, a crown is required so that the tooth structure can be held together as a whole.  ​ 
After the restoration is placed, the root canal treated tooth can function as a natural tooth in the mouth, and is safe to be chewed on. 

 
How long does a Root Canal last? 

The lifespan of a root canal treated tooth depends on how well oral hygiene and check ups are maintained.  ​On rare occasions, there might be complications, such as secondary infection or a fracture in the root. On such occasions, additional treatment would be indicated.
