The prepared canals are then irrigated with a variety of cleaning solutions to thoroughly clean the inside of the root canal system. Generally the canals are irrigated using small syringes although a variety of techniques are currently available. The irrigation process removes residual infected pulp tissue, debris from the preparation of the canals and also bacteria that are present in the canals. Thorough cleaning is required to ensure the canal is clean and this can take a reasonable period of time to achieve a clean canal. The canals are then dried with paper points or suction tips.
