  • Many times tooth becomes weak due to drilling and making of access cavity in the process of the root canal.
  • In cases where the dentist has difficulty in finding the root canals, she has to remove a more significant amount of tooth structure to locate the root canals; this makes the tooth weak.
  • The dentist also needs to remove more tooth structure in cases of severe tooth decay. Due to the removal of more tooth structure, the tooth becomes weak.
  • The strength of the dentin which is the calcified portion of the tooth reduces due to the chemicals used in the cleaning process of the root canal treatment.

Seal the tooth

After the infected tooth pulp is removed, the hollow of the tooth needs to be sealed to protect it from contamination by saliva and infections. For this purpose, the tooth needs to be sealed with dental filling materials and then protected with the crown.
