Dentistry/Types of composites


Can you please explain the difference between a flowable and stackable composite filling and how each is used to fill a tooth that had a cavity?

Thank you!

Hi Susan,

Flowable composite has more resin (versus fillers) so it flows more and is ideal for a deeper part of a cavity.  Stackable or Packable composite has more fillers, used traditionally for the bulk of a filling.  Most dentists will use a combination of the two when doing a filling depending on how deep the cavity is.

Hope this helps,
