In endodontics, files play a crucial role in the preparation of the root canal system. They are specifically designed tools used to enlarge and smooth the canal walls during root canal therapy. This process is essential because it helps to create enough space to effectively clean and shape the canal, allowing for the optimal removal of infected or necrotic tissue. By enlarging the canal, endodontic files facilitate the subsequent filling with materials that seal the canal and prevent reinfection.

The design of endodontic files, with their various taper and size options, aids in removing debris and ensuring that the entire canal system is adequately treated. This step is vital for successful endodontic treatment, as it prevents the possibility of complications and ensures that the tooth can be preserved.

While draining abscesses is an important aspect of managing root canal infections, it typically involves other techniques and instruments rather than files. Supporting an electric pulp tester is related to testing vitality but does not pertain to the function of files in canal shaping. Removing excess gutta percha may also be a necessary step in some procedures, but it involves different tools specifically designed for that purpose rather than the files used for canal shaping.
