What are viewers and players (plug-ins)?
Some NIDCR web pages have links to files that may require software downloads--called "plug-ins"-- to help you properly view or play these files. Plug-ins are optional software additions that let you watch Internet movies and animation, hear sound and music, and read special Adobe documents, for example.
