Doctor im 18 yrs old i have got pulpitis so the dentist told that i need to undergo root canal..will they place a crown ?

Crown: Crowns are done after root canals to provide them with enough strength for chewing and biting and prevent the from breaking. So most teeth need crowns after root canal.

Possibly: Depends on which tooth and how large the defect is. More often than not crowns are placed, but there are exceptions.

Usually: Root canaled teeth are weakened. So dentists often recommend a crown to strengthen tooth.

Often recommended: After the root canal, a permanent filling or crown is always needed. The reason they are recommended frequently is that a dental crown is often the best option to extend the life of a tooth for years to come.
